The electrical efficiency is defined as the ratio between the useful power output and the total power input:

In our problem,

(power generated by the solar panel) and

(power hitting the surface of the solar panel), therefore the efficiency of the panel is

which corresponds to 30%.
Answer:
Our eyes are most sensitive to the wavelengths corresponding to the yellow and green colors of the spectrum. Flashy signs and some fire engines are painted in a yellowish-green color to attract our attention.
Answer:
38.77 kg
Explanation:
The weight of an object is given by:
Weight = mg, g = acceleration due to gravity ( 9.8 m/s square)
and m is the mass.
So, in this case:
Weight of dog is 382 N, so, by putting the values of weight and g into the equation we will get the mass of dog.
382 = mass multiply with 9.8
so, the mass of the dog will be 38.77 kg
Velocity = The speed and direction that an object is moving at
The formula to solve this is (.80)^3 X 6 and the answer would be 3.1 feet. That is how high the ball will rebound after its third bounce. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
