The spring constant of the given spring is equal to  3.2 × 10⁶ N/m.

An equation that represents the spring force is as follows:

F = -kx,

where x is the spring's potential deformation and k is a spring constant. The spring will revert to its previous form or position if the sign is negative.

When a spring is crushed, it stores the following amount of energy:

E = (1/2)kx²

Given that E = 1000J, the energy that the spring stores when it is squeezed.

x = 2.5 cm = 0.025 m is the length by which a spring is compressed.

1000 = (1/2)×k (0.025)(0.025)

k = 3.2 × 10⁶N/m

F = -kx. Spring constant is the name given to the proportional constant k. It represents a stiffness measurement for the spring. A spring produces a force F = -kx in the direction of its equilibrium position when it is stretched or compressed by a distance x from its equilibrium length.

If a flight is made from an area of lower pressure into an area of high pressure without the altimeter setting being adjusted, the altimeter will indicate option c - lower than the actual altitude above sea level.

When flying from a lower pressure area to a high-pressure area, the aircraft's altitude gradually rises while the altimeter remains constant; thus, the ALTIMETER indicates a lower altitude than the aircraft is actually flying. The quantity of gas particles with in air reduces as height increases atmosphere becomes less dense than air nearer to ocean level.

The minimum coefficient of static friction between the man and the train accelerating at 0.20g is .020.

The acceleration of the train is 0.20g. g is the acceleration due to gravity.

The man standing in the train will also have the same acceleration as that of the train. So, the acceleration of the man standing in the train is 0.20g.

Let us assume that the mass of the man is M.

So,

in order to keep standing an go with the trains,

Friction force = The force on the man exerted by the train's acceleration.

Friction force = uN

u is the coefficient of static friction,

N is the normal reaction.

The Normal reaction will be equal to the weight of the man.

Weight of the man wil be mg. So,

Friction force = uMg

3. Cause of various properties. Different light sources have distinct spectra due to their unique features, such as composition and temperature. Because fluorescent light is composed of a unique blend of hues, it differs slightly in appearance from sunlight.

4. Rainbow - A rainbow is a natural illustration of a spectrum. Optics-studying scientists initially employed the term spectrum. They used the term to describe the spectrum of colors produced by a prism on visible light. The spectrum observed when light passes through a prism is an illustration of light dispersion.

5. Dispersion - The distinct hues correspond to different wavelengths of light and are refracted to varying degrees. This separation of hues is referred to as dispersion. Once sunlight's hues are separated through refraction, we are able to recognize them in the rainbow's grandeur.

The approximate kinetic energy of the brick just before it touches the ground is 75J. Option A.

Solution:

Mass of brick = m = 2.5 kg

Height of roof = 3 m

Let v be the final velocity of the brick just before hitting the ground.

The kinetic energy of an object is given by KE = [tex]\frac{1}{2} *M *V^{2}[/tex]

v must be calculated before calculating KE.

You can calculate the required variables using the formula where u is the initial velocity, v is the final velocity, a is the acceleration, and s is the distance traveled.

Where s = roof height, u = 0 because the brick falls instead of being thrown, so a = gravitational acceleration = g = 9.8.[tex]\frac{M}{S^{2} }[/tex]

So[tex]V^{2}[/tex] = 0+2x9.8x3 = 58.8

So v = [tex]\sqrt{58.8}[/tex] = 7.66m/s

Now we can calculate the kinetic energy = [tex]\frac{1}{2} *m*v^{2} = \frac{1}{2} *2.5*58.8 = 73.5 kg*\frac{m^{2} }{s^{2} }[/tex]

We also need to convert KE to Joules.

[tex]1kg*\frac{m^{2} }{s^{2} }[/tex] = 1 joule

Therefore kinetic energy = 73.5 joules.

When an object falls from rest its gravitational potential energy is converted into kinetic energy. Energy conservation as a tool allows us to calculate the velocity just before hitting the surface. When an object hits solid ground, all of its kinetic energy is converted into heat and sound energy. When an object falls to the ground in free fall its potential energy decreases, and its kinetic energy increases.
