There is not enough information given to answer with. The force of gravity at the planet's surface depends on the planet's radius as well as its mass. The planet could have exactly the same mass as Earth has. But if it's radius is only 71% of Earth's radius, then gravity on its surface will be twice as strong as gravity on Earth.
Answer:
Acceleration = 10.06 m/s²
Explanation:
1 mile = 1.6093km
1609.3m = 1 mile
1 m =
mile
50.0 miles/hour =
m/s
= 22.35m/s
from equation
S = Ut + 1/2 at²
v = U + at
22.35 = 0 + a * 2.22
a = 22.35 ÷ 2.22
= 10.06 m/s²
Answer:
a) 
b) 
Explanation:
Given:
- mass of raindrops,

- charge on the raindrops,

- horizontal distance between the raindrops,

A)
<u>From the Coulomb's Law the force between the charges is given as:</u>

we have:

<em>Now force:</em>


B)
<u>Now the acceleration on the raindrops due to the electrostatic force:</u>
