Answer:
Option D 3.9
Explanation:
First, you need to use the correct equation which is the following:
COP = Q/W
Where:
Q = heat absorbed
W = work done by the pump
COP = coefficient of perfomance
We have all the data, so, all you need to do is replace in the above expression and you shoould get the correct result:
COP = 30 / 7.7
COP = 3.896
This result you can round it to 3.9. option D.

Answer and Explanation:
1. Evidence can be observed that light is energy-consuming because the liquid crystal sheet sets the temperature and gets warmer. With this, we can affirm that the light energy, moved the liquid crystal sheet molecules, making them when they move generate heat.
2. The evidence that light loads energy can be seen through the movement of the toy. This is because the light states that there was energy received, which will make all the gear of the toy work and move it.
