The average annual solar flux in New York is 250 W/m2. Suppose 10 m2 of solar electric panels operating at 10% efficiency were installed on a home there. A) How many kWh of electricity could be collected by these panels in one year?

B) What fraction of the annual electrical requirement of 10,000 kWh for the average home does this represent?

C) How many square meters of solar panels would be required to supply 10,000 kWh per year?

step-by-step explanation:

10 - 2.8 = 7.2

2 2/5 = 2.4

7.2 / 2.4 = 3

where are the vectors ?

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
