Answer:
TEMPERATURE
Explanation:
When a wave is absorbed by a material medium, different phenomena occur, but the collisions with the other particles causes the energy to be transformed into internal energy in the atoms and molecules of the material, with TEMPERATURE measurements the increase in the internal energy of the material.
Answer:
Both are chemical change as the new product is formed with new characteristics and can't be brought back to previous form.
It can impact the waters by polluting it and impact fish life's and if we have a drought we can't use this power source
Answer:
The change in angular momentum is 
Explanation:
From the question we are told that
The initial angular velocity of the spinning top is 
The angular velocity after it slow down is 
The time for it to slow down is 
The rotational inertia due to friction is 
Generally the change in the angular momentum is mathematically represented as

substituting values


The motion of falling objects is the simplest and most common example of motion with changing velocity. The early pioneers of physics had a correct intuition that the way things drop was a message directly from Nature herself about how the universe worked. Other examples seem less likely to have deep significance. A walking person who speeds up is making a conscious choice. If one stretch of a river flows more rapidly than another, it may be only because the channel is narrower there, which is just an accident of the local geography. But there is something impressively consistent, universal, and inexorable about the way things fall.
