Answer: The energy incident on the solar panel during that day is .
Explanation:
Given: Mass = 250 kg
Initial temperature =
Final temperature =
Specific heat capacity = 4200
Formula used to calculate the energy is as follows.
where,
q = heat energy
m = mass of substance
C = specific heat capacity
= initial temperature
= final temperature
Substitute the values into above formula as follows.
As it is given that water absorbs 25% of the energy incident on the solar panel. Hence, energy incident on the solar panel can be calculated as follows.
Thus, we can conclude that the energy incident on the solar panel during that day is .
It is the 'crest' part that the green arrow is identifying.
