A photovoltaic array of (solar cells) is 10.0% efficient in gathering solar energy and converting it to electricity. If the average intensity of sunlight on one day is 700 W/m2, what area (in m2) should your array have to gather energy at the rate of 170 W?

Explanation:

Given:

Power = 170 W

Power intensity = 700 W/m^2

Formula:

Power intensity = power/area

Area = 170/700

= 0.243 m^2.

The speed at the first quarter checkpoint is 0.74 m/s. The speed at the second quarter checkpoint is 1.40 m/s. The speed at the third quarter checkpoint is 1.61 m/s. The speed at the finish line is 1.89 m/s.

Explanation: I did the assignment and got it correct :)
