Answer:
400000
Explanation:
So first solve one part:
(3.25 * 10^5)
(3.25 * 100,000)
= 325000
Then solve the next part:
(7.5 * 10^4)
(7.5 * 10000)
= 75000
Now lastly, add the two answers:
325000 + 75000 = 400000
Therefore,
(3.25 x 10^5) + (7.5 x 10^4) = 400000

The force of gravity between two objects is:
F = G*m1*m2/r^2
So, it is dependent of the two masses and the distance between their centers of mass.
Answer:
2.83 x 10^4m/s
Explanation:
First, let us calculate the time taken by the object to hit the surface of the earth.
H = 4.1 x 10^7m
g = 9.8m/s2
t = √(2H/g)
t = √((2x 4.1 x 10^7) /9.8)
t = 2892.64secs
Now, we can find the velocity with which the object strikes the earth as follows:
V = gt
V = 9.8 x 2892.64
V = 2.83 x 10^4m/s
