Sunlight strikes a solar panel. which is then used to power the lights in the house. What are the energy transformation taking place in this system A)light energy to electric energy to mechanic energy
B)thermal energy to electric energy to light energy
C)light energy to electric energy to light energy
D)thermal energy to chemical energy to kinetic energy

Thermal energy to electric energy to light energy

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
