W = F x d
F: 450 N
d = 10 m
plug your variables into the equation to get W = 450N x 10m

Answer:
A and B are both requirements for a solar panel to generate usable current at home.
Explanation:
Solar panel operates through a group of cells, where each one of them captures/convert electrons making them move from one polarised region to another. The excited electrons can move from a region in excess of electrons (p region) to a region with a lack of electrons (n region).
This physical effect of electron moving from one side to another creates what we know as current flow.
This current flow from a solar panel does not vary with time in a determined frequency, so it's constant. This is the definition of a DC current. Since the household devices work with AC (variable sinusoidal current Alternate Current) a converter DC to AC is required.
Due to the fact that the solar panels only operate in the day when they recibe direct sunlight, there is the need to have batteries to store the energy for the night and the times where the sunlight is not enough to provide enough electron flow.
