The gravitational acceleration on the surface of planet A is:
where G is the gravitational constant,
is the mass of planet A and
its radius.
Similarly, the gravitational acceleration on the surface of planet B is:
The ratio between the gravitational acceleration on planet A and B becomes:
The problem says that the two masses are equal:
while planet A has 3 times the radius of planet B:
. Substituting into the ratio, we get:
so, gravity on planet B is 9 times stronger than planet A.
Answer:
Explanation:
strike-slip, normal and thrust
mark her as brainiest, :) I don't need it :P
Answer:
We define voltage as the amount of potential energy between two points on a circuit. One point has more charge than another. This difference in charge between the two points is called voltage.
