In the absence of an external force, the total linear momentum of the system maintains conservation, indicating that the speed of the system's center of mass is constant.

This is because the spring force between the masses acts as an internal force between the two masses.

The product of an object's mass, m, and velocity, v, is known as linear momentum, and it is a vector quantity. In order to express it and refer to momentum informally, the letter "p" is utilized. You should be aware that a body's momentum always points in the same direction as its velocity vector. Because it is a conserved quantity, the overall momentum of a system is always constant. Linear momentum is measured in kg/s.

The total linear momentum prior to an object's interaction and the total linear momentum following that interaction is identical. Any system of objects that is subject to no net external force has a constant total linear momentum.

When the gymnast starts to jump his potential energy starts to convert to kinetic energy. But when he reaches the maximum height and stop there for seconds, potential energy regains. Thus, option C is correct.

Potential energy of an object is the energy stored in it by virtue of its position. Potential energy increases with increases in mass and height which is clear from the equation for potential energy

p = mgh

Kinetic energy is generated by motion of the object. Thus, only a moving body attains a kinetic energy. Kinetic energy depends on the mass and velocity of the object.

The distance that the bullet penetrates is 0.03m.

Given data:

The mass of the bullet is

m = 25 g = 0.025 kg

The bullet's initial velocity is

u = 350 m/s

The final velocity of the bullet is

v = 0

The average force opposing the motion is

F = 50000N

From Newton's second law, the acceleration derived as,

F = m. a.

a = F. m..........(1)

Substituting values in equation (1), we get:

a = 50000 N / 0.025 kg = 2×106 m/s 2

The equation of motion is,

v 2=u 2−2 a S

2 a S=u 2−v 2

S = u 2−v 2/2 a.......(2)

Answer:

amplitude:1m

period:10s

Explanation:

The degeneracies of the first, fourth and fifth energy levels for the three dimensionsal cubical box are 1, 3 and 1.

Calculation :

Given Data

A three-dimensional cubic box with

lx=ly=lz=Li.

For a 3D cubic box, the energy of the particle in a box is having a formula given below,

E3D=h²8m(n²x/l²x+n²y/l²y+n²z/l²z)

Given,

lx=ly=lz=Li, put in the above equation, we get,

E3D=h²/8m(n²x/L²+n²y/L²+n²z/L²)

E3D=h²/8mL²(n²x+n²y+n²z)

Now, for the First energy level, the energy will be,

E3D=h²/8mL²(1²+1²+1²)

E3D=3h²/8mL²

The degeneracy is equal to 1 because nx=ny=nz=1.

Now, for the Fourth energy level, the energy will be,

E3D=h²/8mL²(1²+1²+3²)

E3D=h²/8mL²(1+1+9)

E3D=11h²8mL²

The degeneracy is equal to 3 because, nx=1,ny=1,nz=3,nx=1,ny=3,nz=1 and nx=3,ny=1,nz=1.

Now, for the Fifth energy level, the energy will be,

E3D=h²/8mL²(2²+2²+2²)

E3D=h²/8mL²(4+4+4)

E3D=12h²/8mL²

The degeneracy is equal to 1 because nx=2,ny=2,nz=2.

Therefore, the degeneracies of the first, fourth and fifth energy levels are 1, 3 and 1.

Energy levels are degenerate if they correspond to two or more different measurable states of a quantum system. Conversely, two or more distinct states of a quantum mechanical system are said to be degenerate if they have the same energy value when measured. The number of different states corresponding to a particular energy level is called the degeneracy of the level.

The length L₂ for destructive interference is  L₂ = 22 m

A sound wave is a mechanical wave which carries sound energy from one point to another.

Since two point sources S₁ and S₂, Which are in phase and emit identical sound waves of wavelength 2.0 m: The length L₁ = 21 m. A listener stands at point P: Assume the amplitude of individual sound reaching at point P does not change, to find L₂, we need to know the path difference for destructive interference.

The path difference for destructive interference is given by ΔL = (n + 1)λ/2

where

Since we require the least intensity, we have the minimum interference. So, n = 0.

So, ΔL = (n + 1)λ/2

ΔL = (0 + 1)λ/2

L₂ - L₁ = λ/2

So, making L₂ subject of the formula, we have

L₂ = L₁ + λ/2

Given that

Substituting the values of the variables into the equation, we have that

L₂ = L₁ + λ/2

L₂ = 21 m + 2.0 m/2

L₂ = 21 m + 1 m

In this case, we are given that the rod is subjected to the force system shown in the figure. There is a vertical force F acting on the rod at point A, as well as a horizontal force P. The rod is also subjected to a moment M about the z-axis.

To determine the stress components that act at point A, we need to consider the forces that are acting on a small volume element located at this point.

The stress on a volume element is defined as the force acting on the element per unit area. The stress components at a point can be represented by a stress tensor, which is a 3x3 matrix with nine elements. The diagonal elements of the stress tensor represent the normal stress components, while the off-diagonal elements represent the shear stress components.

To determine the stress components at point A, we need to consider how these forces are distributed over the surface of the volume element. The normal stress components can be found by considering the forces acting perpendicular to the surface of the element. The shear stress components can be found by considering the forces acting tangent to the surface of the element.

For example, the normal stress component in the x-direction at point A can be found by considering the force F acting perpendicular to the surface of the element in the y-direction. The normal stress component in the y-direction at point A can be found by considering the force P acting perpendicular to the surface of the element in the x-direction. The shear stress component in the XY-plane at point A can be found by considering the moment M acting tangent to the surface of the element.

To determine the specific values of the stress components, we would need to know the dimensions of the volume element, as well as the magnitudes of the forces and moments acting on the rod. With this information, we can use the equations of statics to solve for the stress components at point A.

If two metal blocks of different masses slide freely down the same frictionless incline, option a is correct.

Objects accelerate due to imbalanced forces. However, not every item accelerates at the same rate in the presence of the same imbalanced force. As a result, the speed and net force in the direction perpendicular to the plane must both be zero. Since the plane is assumed to be "frictionless," no force is applied to the block that is perpendicular to the surface by the plane. The acceleration is determined by multiplying the acceleration of gravity by the sine of the angle for a frictionless incline of angle degrees. The force of gravity is not parallel to the surface when there is an inclination. The normal force diminishes as the angle of the incline increases, which reduces the frictional force. You can increase the inclination until the thing barely starts to slip.
