What is the potential problem with solar energy?

The problem states it's a parallel-plate air capcitor made using two plates .07m square, spaced 3.4mm apart. What must the potential difference between the plates be to produce an energy density of .089 J/m^3 ?

The average solar radiation incident on the surface of the earth is about 1 KW/m2 for the entire year. A solar house is built with solar panels installed in the roof to provide the heating and electrical energy of the house. If the roof has a surface...

A rocket of mass 6.0 kg takes off from the ground and goes straight up. During the first 100 meters of its ascent, the engine exerts a 80 newton upward force on the rocket. A. How much work does the engine do on the rocket during those first 100 meters...

A body which is under the direct influence of gravity has potential energy. if the body starts moving vertically upwards (crossing even the escape velocity), it loses potential energy which is converted into kinetic energy. IF EARTH IS SAID TO MOVE VERTICALLY...

When I was in college, my campus was visited by an 18 wheeler that ran completely on solar energy. It was created for the Greenpeace Organization and was making a tour of the continental US promoting the use of solar energy. That was about 10 years ago...

Problem: a body fire vertically reaches a max height of 120m. What is the location at which the kinetic energy is 75% of the potential energy. Now I figured the way to set this up would be KE=.75PE>>> so (1/2)(m)(V^2)=(.75)(m)(g)(h)... the m...

Juggles and Bangles are clowns. Juggles stands on one end of a teeter totter at rest on the ground. Bangles jumps off a platform 2.5m above the ground and lands on the other end of the teeter totter, launching Juggles in the air. Juggle rises to a height...
