What kind of work does gravity acting on a raindrop weighing 20 mg do when it is blown from a height of 2 km?
| November 23, 2020 | education
The work force of gravity is equal to: A = Fs, – where F is the modulus of the force of gravity; s-moving raindrop
F = mg, where g = 10 (m / s ^ 2)
Convert milligrams to kilograms: 20mg = 0.00002kg
And kilometers to meters: 2km = 2000m
substitute in the formula:
A = 0.00002kg * 10m / s ^ 2 * 2000m = 0.4 J
Answer: 0.4J
