Answer:
4 times the mass of Earth
Explanation:
= Mass of Earth
= Mass of the other planet
r = Radius of Earth
2r = Radius of the other planet
m = Mass of object
The force of gravity on an object on Earth is

The force of gravity on an object on the other planet is

As the forces are equal

So, the other planet would have 4 times the mass of Earth
Answer:
Scientific theories and laws develop from the acquisition of scientific knowledge.
Explanation:
t
Answer:
-6 m/s²
Explanation:
Given:
v₀ = 50 m/s
v = 20 m/s
t = 5 s
Find: a
v = at + v₀
20 m/s = a (5 s) + 50 m/s
a = -6 m/s²
Answer: 6.67 x 10^-11 m^3•kg^-1•s^-2
