The option “The sum emitting light energy” does not describe the conversion of potential energy to kinetic energy.
Answer: Option A
<u>Explanation:
</u>
The potential energy, the object's energy at rest while the kinetic energy is the energy the object in motion. So among the options given, a rocket leaving the Earth's atmosphere consists of conversion of potential energy as the thrusting force to kinetic energy of the movement of the rocket to space.
Similarly the stretching of rubber band is a form of elastic potential energy and when it is released, the band will vibrate which will be the converted kinetic energy.
Also, the avalanche is the falling of ice berg which were once in rest, so the potential energy of the ice berg will get converted to kinetic energy during avalanche.
The option that is the sun emitting light does not convert potential to kinetic energy, instead it converts potential to light energy.
It depends on the size of the cube, but you could use a ruler for almost any size, or if it is small enough, you could use a caliper to get a very precise measurement.
Answer
given,
k = 250 N/m
q = 900 N/m³
(FSp)s=−kΔs−q(Δs)^3
work done = Force x displacement
limits are x = 0 to x = 0.15 m
work done
![W = [\dfrac{kx^2}{2}+\dfrac{qx^4}{4}+ C]_0^0.15](https://tex.z-dn.net/?f=W%20%3D%20%5B%5Cdfrac%7Bkx%5E2%7D%7B2%7D%2B%5Cdfrac%7Bqx%5E4%7D%7B4%7D%2B%20C%5D_0%5E0.15)
W = 3.375 + 0.1139
W = 3.3488 J

Answer:
Kinetic energy of an object can't be greater than potential energy.
Explanation:
This is due to the reason that some of the energy is lost in the form of friction, heat energy, light energy etc. For example, a ball bounces to a height h in its first bounce.
