How Do The Reactants In A Fission Reaction Differ From Those In A Fusion Reaction? (2024)

Physics High School

Answers

Answer 1

In a fission reaction, the reactants are typically two or more atoms of a heavy element, such as uranium.

What is fusion reaction?

Fusion reaction is the process of combining two atomic nuclei to form a single, larger nucleus. This process releases a large amount of energy, which can be harnessed to generate electricity or to power spacecraft. Fusion reactions occur naturally in stars, and scientists have been trying to replicate the process on Earth for decades. In a fusion reaction, two atomic nuclei are fused together at extremely high temperatures, forming a single, larger nucleus, and releasing a large amount of energy in the process.

When these atoms collide, they break apart, releasing large amounts of energy in the form of gamma radiation. In contrast, the reactants in a fusion reaction are typically two or more small atoms such as hydrogen. When these atoms come together, they fuse, releasing even larger amounts of energy in the form of gamma radiation. The energy released in a fusion reaction is much greater than that of a fission reaction.

Answers

The kinetic energy of the spring is obtained as 12 J. Option C

What is the kinetic energy of the spring?

We know that the kinetic energy is the energy that is required to stretch the spring. We can use the graph that has been shown to show the force constant of the spring.

We can find the force constant as the slope of the graph as follows;

K = [tex]y_{2} - y_{1} /x_{2} - x_{1}[/tex]

K = 60 - 0/0.3 - 0.2

K = 60/0.1

K = 600 N/m

We then have;

W = KE = 1/2 Kx^2

Thus;

KE = 0.5 * 600 * (20 * 10^-2)^2

KE = 12 J

It would have a kinetic energy of 12 J.

what frequency would a 1.6-ft-long nylon string that has a thickness of 3/32 in produce (a) if put under an equal tension? (b) if put under one-third of the original tension?

Answers

a) The frequency would a 1.6-ft-long nylon string that has a thickness of 3/32 in produce if put under an equal tension is 3.74 x [tex]10^{-5}[/tex] kg/m.

b) The frequency would a 1.6-ft-long nylon string that has a thickness of 3/32 in produce if put under one-third of the original tension is 0.577.

The frequency of a string under tension is given by the equation f = (1 / 2L) × √(T / mu)

where f is the frequency, L is the length of the string, T is the tension in the string, and mu is the linear mass density of the string.

To calculate the frequency of a 1.6-ft-long nylon string with a thickness of 3/32 in, we need to first determine the linear mass density of the string. The linear mass density of a string is given by the formula:

mu = (m / L) = (p × A) / L

where mu is the linear mass density, m is the mass of the string, p is the density of the material of the string, A is the cross-sectional area of the string, and L is the length of the string.

The density of nylon is approximately 1.15 g/cm^3, and the cross-sectional area of the string can be calculated from its thickness:

A = (3/32 in)² × pi = 0.0293 in²

Converting the length of the string to inches, we get:

L = 1.6 ft × 12 in/ft = 19.2 in

Substituting these values into the equation for linear mass density, we get mu = (1.15 g/cm³ × 0.0293 in²) / 19.2 in = 0.00146 g/in

Converting this to the units used in the frequency equation, we get mu = 0.00146 g/in × 1 kg/1000 g × 1 m/39.37 in = 3.74 x [tex]10^{-5}[/tex] kg/m

Now that we have calculated the linear mass density of the string, we can use the frequency equation to determine the frequency of the string under different tensions.

(a) If the string is put under equal tension, the frequency is given by f = (1 / 2L)

b) The original tension in the string is T and the string is put under a tension of T/3, the frequency will be reduced by a factor of √(1/3) = 0.577, or about 58% of the original frequency.

electrons accelerated from rest through a 63.6 kv potential difference strike a tungsten target, causing it to emit x-rays. what is the shortest wavelength (in nm) of radiation emitted by the target?

Answers

The shortest wavelength of radiation emitted by the tungsten target is 187 nm.

The shortest wavelength of radiation emitted by the tungsten target is determined by the energy of the electrons that strike the target. The energy of the electrons can be calculated using the equation:

E = qV

where E is the energy of the electrons, q is the charge of the electrons (1.60 x [tex]10^{-19}[/tex] C), and V is the potential difference through which the electrons are accelerated.

In this case, V = 63.6 kV = 63.6 x [tex]10^3[/tex] V, so the energy of the electrons is:

E = 1.60 x [tex]10^{-19}[/tex] C * 63.6 x [tex]10^3[/tex] V = 1.02 x [tex]10^{-15}[/tex] J

The shortest wavelength of radiation emitted by the tungsten target is then determined by the energy of the electrons using the equation:

lambda = hc / E

where lambda is the wavelength of the radiation, h is the Planck constant (6.63 x [tex]10^{-34}[/tex] J s), c is the speed of light (2.998 x [tex]10^8[/tex] m/s), and E is the energy of the electrons.

Substituting the values into this equation, we get:

lambda = 6.63 x [tex]10^{-34}[/tex] J s × 2.998 x [tex]10^8[/tex] m/s / 1.02 x [tex]10^{-15}[/tex] J = 1.87 x [tex]10^{-7}[/tex] m

Converting this to nanometers (nm), we get:

lambda (nm) = 1.87 x [tex]10^{-7}[/tex] m * [tex]10^{9}[/tex] nm/m = 187 nm.

on the line between the speakers there are points where maximum sound intensity occurs. what is the distance of the nearest point from speaker a?

Answers

The distance of the nearest point from speaker A is half of the distance between the speakers.

This is due to constructive interference, which is the phenomenon that occurs when two sound waves of equal frequency combine to produce a wave of greater amplitude. When two sound waves of equal frequency and amplitude meet in phase, the sound pressure of the combined wave is the sum of the two individual waves. When this occurs, the pressure at the point of constructive interference is twice that of the individual waves and the intensity is four times the intensity of each of the individual waves. The equation for the distance between the points of maximum sound intensity is 2d = λ/2, where λ is the wavelength of the sound wave. The wavelength of a sound wave is related to its frequency by λ = v/f, where v is the speed of sound and f is the frequency of the sound. The speed of sound is approximately 340 m/s in air, so if the frequency is known, the equation can be used to calculate the distance between the speakers.

Traverse Surveying is a popular surveying method.

Traversing is a type of survey in which several connected survey lines form a skeleton, and the directions and lengths of the survey lines are measured using a protractor and a tape or chain.

Surveying is basically of two types:

Closed traverse: When the lines form a circuit that ends at the starting point, it is called a closed traverse.Open Traverse: When the lines forming a circuit end somewhere other than the starting point, it is said to be an open traverse.

The errors in the surveying can be found out by angles induced in transverse.

The sum of the measured internal angles should be equal to (2N-4), where N=number of sides of the traverse.

Number of stations = N = 8

Sum of the interior angles = (2N - 4)

in projectile motion why does an object have a nonzero instantaneous acceleration stop rising and falling

Answers

An object have a nonzero instantaneous acceleration during projectile motion is because the gravitational force acting on the body is in the downward direction.

For a projectile motion, the gravitational force following up on the body is in the descending bearing. Hence, the body in a shot movement has speed increase because of gravity 9.8 m/s2. It should be noticed that no power is following up on the body in the shot movement in the flat heading.

At the point when a molecule is tossed diagonally close to the world's surface, it moves along a bended way under consistent speed increase coordinated towards the focal point of the earth (we expect that the molecule stays near the world's surface). The way of such a molecule is known as a shot, and the movement is called shot movement.

In a projectile motion, there are two synchronous free rectilinear movements:

Along the x-pivot: uniform speed, answerable for the flat (forward) movement of the molecule.

Along the y-pivot: uniform speed increase, answerable for the vertical (downwards) movement of the molecule.

if jed and kadia use the one-dimensional conservation of momentum equation to find the final velocity of the two joined objects after the collision, what do they obtain? (indicate the direction with the sign of your answer.)

Answers

The final velocity of the two joined objects after the collision would be 0 m/s (0)

This can be obtained by using the one-dimensional conservation of momentum equation, p = m1v1 + m2v2, where m1 and m2 are the masses of the two objects, and v1 and v2 are their initial velocities. Since the two objects are joined after the collision, the final velocities of both objects are the same. Therefore, if we set v2 to equal the negative of v1 and solve for v1, we get 0 m/s. This shows that the final velocity of the two joined objects is 0 m/s since the momentum of the system is conserved.

According to the Nebular Theory of Solar System Function, the solid planetesimals are able to grow larger in the outer solar system than in the inner solar system because only metal and rock could condense in the inner solar system, while ice also condensed in the outer solar system.

Terrestrial planets formed where only dense materials could condense, which doesn't apply for Jovian planets. That's why they're rocky and small while the ones that couldn't condense dense materials are large and gaseous and found further away from the star.

The types of objects found within the solar system provide significant clues and evidence to support the Nebular Theory.

Taking into account the Newton's second law, the acceleration of the 100 g mass is 50 m/s².

Newton's second law

Newton's second law states that this force will change the speed of an object because the acceleration and/or direction will change.

So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object:

F= m×a

What kind of power is employed to open doors?

You have chemical potential energy (energy stored within you), and the motion of pushing the door with your hands had kinetic energy as well (energy in the motion of your hands). Your kinetic and potential energy were converted into mechanical energy when you pushed the door, which resulted in work being done (door opened).

Springs are constructed from substances like spring steel, which, when compressed, stretched, or twisted, reverts to its original shape. Elastic potential energy, which the spring stores when it is bent from its free state and then releases when the spring is unwound, is stored in the deformed state.

a satellite of mass m has an orbital period t when it is in a circular orbit of radius r around the earth. if the satellite instead had mass 4m, its orbital period would be

Answers

The orbital period is independent of the satellite mass, which means that every satellite orbiting the earth at a radius R has an orbital period A regardless of its mass so option option -A is correct.

What is orbital period?

The duration of one orbit around another astronomical object is known as the orbital period (also known as the revolution period). It typically refers to bodies like planets or asteroids that orbit the Sun, moons that orbit other planets, exoplanets that orbit other stars, or binary stars.

According to Kepler's third law, a satellite's orbital period (T) depends on the mass and radius of the object it orbits:

T = 2π[tex]R^{3/2}[/tex]/[tex]\sqrt{GM}[/tex]

As a result, the orbital period is independent of the satellite's mass, which means that regardless of mass, every satellite orbiting the earth at a radius R has an orbital period A.

what is the moment of inertia about the cm? what is the moment of inertia about an axis through the pivot?

Answers

The moment of inertia,I of this assembly about the axis through which it is pivoted is [tex]I=x^2(m_1+m_2+\frac{m_r}{3})[/tex]

From figure,

we can observe that the data,

[tex]m_1[/tex] = sphere 1's mass

[tex]m_2[/tex] = sphere 2's mass

[tex]m_r[/tex] = the weight of the rod

x= the distance between sphere 1 and pivot

x= the distance between sphere 2 and pivot

2x = total length of the rod

We must determine the expression of the sphere's moment of inertia and the expression of the rod's moment of inertia.

The formula for moment of inertia of sphere is expressed as,

[tex]I=mr^2...i[/tex]

Where, m=mass of sphere

r=distance between sphere and pivot

The formula for moment of inertia of rod can be expressed as ,

[tex]I=\frac{ml^2}{12}....ii[/tex]

Where,

m=mass of rod

l=length of the rod

Substituting the values of sphere 1 and sphere 2 in the eq. i,

[tex]I_1=m_1x^2\\\\I_2=m_2x^2[/tex]

substitute the values of rod in the moment of inertia in eq.ii

[tex]I_r=\frac{m_r(2x)^2}{12}\\\\I_r=\frac{4m_rx^2}{12}\\\\I_r=\frac{m_rx^2}{3}[/tex]

Now, the total moment of inertia is the sum of all the inertias of spheres and the rod,

[tex]I=I_1+I_2+I_r\\\\I=m_1x^2+m_2x^2+\frac{m_rx^2}{3}\\\\I=x^2(m_1+m_2+\frac{m_r}{3})[/tex]

Hence, the moment of inertia of the whole assembly is [tex]I=x^2(m_1+m_2+\frac{m_r}{3})[/tex]

Making sure that there are no gaps that will allow the heat to escape a

answers:
radiation
convection
conduction

Answers

Conduction is a way for heated temperatures to lose heat. The body can rapidly lose heat when swimming or sitting in cool or cold water, which increases the risk of hypothermia. Thus, option C is correct.

What conduction, no gaps that allow the heat to escape?

Because they are poor conductors, insulating materials limit heat loss through conduction. Additionally, the material stops air from moving about inside the chamber, hence minimizing convectional heat loss. Installing loft insulation will help to prevent heat loss via the roof.

Therefore, Insulators should be placed between the patient and good conductors to reduce conduction heat loss. Conduction, no gaps that will allow the heat to escape.

A student is completing an experiment to see how using different metals in a battery will affect the flow of electrons and the
voltage of the battery. The table below shows the electron affinity of four metals.
if paired with silver, which metal would result in no flor of electric charges?

Answers

In order to strengthen the battery, we can alter it to include new metals with even greater differences in electronegativity. Electrons will then flow from Zinc to Lithium.

Three electron-related facts

Electrons in orbit that are negatively charged encircle the outside of the nucleus. Because they rotate so swiftly, it can be difficult for scientists to keep an eye on them. They are the smallest particles in an atom and therefore are drawn to the positive charges of protons; one proton can carry 2000 of them.

Give an example of the an electron.

An electron, that has a negative charge, is the smallest and least substantial part of an atom. Both the protons and electrons are equal in number in a neutral atom. For instance, a hydrogen atom only has one proton or one electron. While the atomic nucleus has 92 protons, which means 92 electrons.
