Which factors affect the gravitational force between objects? Check all that apply. difference in speed of objects direction of
2 answers:
distance between objects
masses of the objects
Explanation:
The magnitude of the gravitational force between two objects is given by
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the distance between the two objects
By looking at the formula, we see that the gravitational force is affected only by two quantities:
- the masses of the objects, m1 and m2
- the distance between the objects, r

Solution:
As per the question:
Coefficient of linear expansion of Copper,
Initial Temperature, T = = 273 K
Final Temperature, T' = = 273 + 100 = 373 K
Now,
Initial Volume of the block, V =
where
V' = Final volume
