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%.
The answer to your question will be C. because they are very inexpensive and are readily available but they will eventually deplete because we use them faster than they can be produced we use what has been building up.
You're in luck ! Momentum is the product of (mass) times (velocity).
So if you're given mass and velocity, simply multiply them, and voila,
you have the momentum.
Answer:
constant horizontal force developed in the coupling C = 11.25KN
the friction force developed between the tires of the truck and the road during this time is 33.75KN
