Using Kepler's third law which is defined as the square of the average distance is directly proportional to the cube of the period. It is expressed as P^2 = a^3, Given that the a = average distance is given, the period would be much easier to compute. P = sqrt(27^3) = 140
Answer:
Converted to heat energy
Explanation:
Some of the elastic potential energy is transformed into heat energy. When we stretch a rubber band, it is often observed that the rubber becomes warmer after the stretch and even during the stretch.
Some energy in the band initially at rest will be converted into elastic potential energy and heat energy as it is stretched .
- The heat energy is not usually accounted for since the major concern most times is the elastic energy.
- In this process, heat energy becomes a waste energy.
- By deducing the efficiency, we would find that this transformation is not efficient as predicted by one of the laws of thermodynamics.
Answer:
D. all sounds are caused by vibrations
Explanation:
Answer:
<span>5010J</span>
Explanation:
Work is force times distance, or
<span>W=F⋅d</span>.
Substitute in values from the question to get
<span>W=8.35⋅<span>102</span>N⋅6m=50.1⋅<span>102</span>Nm=5010<span>J</span></span>
