A flying hummingbird picks up charge as it moves through the air. This creates a potential near the bird. What is the "voltage of a hummingbird"? Assume that the bird acquires a charge of+200pC, a typical value, and model the bird as a sphere of radius 3 cm.

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

b would be the answer

this would be about 43%

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
