Seismic waves do not travel along the Earth’s surface. The statement is false.

The seismic waves can be defined as the waves full of energy that travel through the Earth's layer, these waves are the result of earthquake.

They can further be divided into two types body wave and surface waves. The body waves travel in the interior of the Earth and the surface waves travel at the surface of the Earth.

The seismic waves can have an amplitude of few centimeters in large earthquake. They travel slower as compared to the body waves.

Hence Seismic waves do not travel along the Earth’s surface. The statement is false.

In nuclear reactors, control rods are used because reactions that occur in a nuclear reactor are highly exothermic in nature.

A nuclear reactor is an apparatus or structure in which  radioactive material can be made to undergo a commanded, self-sufficient nuclear reaction with the resultant release of energy.

Therefore, when these control rods are infused in a nuclear reactor, than it absorbs the neutrons and helps to control the chain reaction. As a result, the rate of chain reaction gets in control.

Thus, we can conclude that the statement control rods are used to slow down the reaction in the reactor core when the core becomes too hot is a true statement.

Thus In nuclear reactors, control rods are used because reactions that occur in a nuclear reactor are highly exothermic in nature.

The position of the object can be used to find the kinetic energy in terms of k and a.

The term kinetic energy refers to the energy of an object that is in motion. The question is incomplete hence the syetem is not shown and the value of the kinetic energy can not be found in terms of  k and a.

Hence, when the system is shown, we can look at the position of the system and use it to obtain the value of the kinetic energy in terms of k and a.

Answer:

K = 3/8k(A)^2

Explanation: Potential Energy --> Conservation of Energy

Because block B is at A/2, U = 1/2k(A/2)^2 which equals U = 1/8k(A)^2.

Now that you have the equation for potential energy, you can find kinetic energy in terms of the spring constant (k) and amplitude (A).

K = 3/8 k A^2

The answer will be A The forces are balanced. Force is an external agent applied on any object to displace it from its position. Force is a vector quantity, so with magnitude it also requires direction.

Force is an external agent applied on any object to displace it from its position. Force is a vector quantity, so with magnitude it also requires direction. Direction is necessary to examine the effect of the force and to find the equilibrium of the force.

The length of each arrow represents the magnitude of each force, while the direction of each arrow represents the direction of each force.

From the diagram, we see that the four arrows have all same length: this means that the four forces have same magnitude, therefore they are balanced in pair. In fact:

On the vertical direction, the normal reaction ([tex]F_N[/tex]) balances the weight of the box ([tex]F_g[/tex])

On the horizontal direction, the push ([tex]F_P[/tex]) balances the force of friction ([tex]F_f[/tex])

Answer:

B, A, A, B

Explanation:

Just trust me on this one.

Explanation:

|F|= B/2

B/2 = √(A²+B²+2ABcosθ) ------(1)

Since the resultant of A and B is perpendicular to Vector A

tan90°= BSinθ/(A+BCosθ)

(A+BCosθ)=0

Cosθ=-A/B ----(2)

Using equation (1)

B/2 = √(A²+B²+2ABcosθ)

B/2 = √(A²+B²+2AB×-A/B)

B/2=√(A²+B²-2A²)

B/2=√(B²-A²)

B²/4=B²-A²

A²=B²-B²/4

A²=3B²/4

A=√3B/2

Using equation (2)

Cosθ=-A/B

Cosθ=-[√3B/2]/B

Cosθ=-√3/2

θ= cos^-1 (-√3/2)

θ= 150°

The net torque on this system is (ml2g-ml1g)k

This refers to the type of force that causes rotation in objects which has mass and is a twisting force

Based on the complete question, we can see the given parameters:

The net torque on this system in which two blocks each of mass m are attached to the ends of a massless rod, above pivot, is (ml₂g-ml_₁g)\hat k.

The torque of a body is the rate of change of angular momentum of the body. Torque is the product of moment of inertia and the angular acceleration.[tex]\tau =I\times \alpha[/tex][tex]\tau=mlg[/tex]

Here, (I) is the moment of inertia and (α) is the angular acceleration.

Two blocks each of the mass m are attached to the ends of a massless rod which pivots as shown in fig.

Initially, the rod is held in the horizontal position and then released. When, the mass was kept at farther to pivot, then the value of torque is,

[tex]\tau=ml_2g\hat k[/tex]

When, the mass was kept at nearer to pivot, then the value of torque is,

[tex]\tau=-ml_1g\hat k[/tex]

Thus, the net torque on this system above pivot is,

[tex]\tau=ml_2g\hat k+(-ml_2g\hat k)\\\tau=(ml_2g-ml_1g)\hat k[/tex]

Thus, the net torque on this system in which two blocks each of mass m are attached to the ends of a massless rod, above pivot is (ml₂g-ml_₁g)\hat k.

Then the algebraic sum of the moment of all the forces about any point is equal to the moment of the resultant force about the same point

If a number of coplanar forces acting on a particle are in equilibrium. then the moment of their resultant is equal to the sum of their individual moment.

If a number of co-planar forces operating on a particle are in equilibrium, the algebraic sum of their moments about any point equals the moment of their resultant force about the same point, according to the law of moments.

Earth has one moon, Mars has two, Neptune has thirteen, Uranus has twenty-seven, Jupiter has sixty-six, and Saturn has sixty-two. Pluto, now classified as a dwarf planet, has five moons.
