That would be like dropping your cell phone on to the ground by accident. The object (cell phone)'s gravitational potential energy would be converted to kinetic energy or energy in motion more precisely. This is just a hypothetical example though.
A) The temperature will increase.
Kinetic energy is the intrinsic energy carried by an object in motion.
Explanation:
Increasing the kinetic energy of the molecules means that molecules rapidly. This causes an increased rate of collision between the molecules and between the molecules and the walls of the container. Most of these collisions are inelastic meaning that some of the energy in the collisions is lost as heat energy to the environment. This means the system becomes hotter.

Solution :
Let
kg
m/s
Let
and
are the speeds of the disk
and
after the collision.
So applying conservation of momentum in the y-direction,





Therefore, the disk 2 have greater velocity and hence more kinetic energy after the collision.
Now applying conservation of momentum in the x-direction,




m/s
So, 
= 4.33 m/s
Therefore, speed of the disk 2 after collision is 4.33 m/s
Answer:
a

b
Explanation:
From the question we are told that
The radius of the flywheel is 
The mass of the flywheel is 
The rotational speed of the flywheel is 
The power supplied by the motor is 
Generally the moment of inertia of the flywheel is mathematically represented as

substituting values


The kinetic energy that is been stored is

substituting values

Generally power is mathematically represented as

=> 
substituting the value

Temperature increase, smaller container, or influx of more gas
