the gravitational force between two objects is ____ proportional to the product of the masses of the objects
1 answer:
Explanation:
There exist a force of gravity between two masses. It is given by :
...........(1)
Where
G is the universal gravitational constant
m₁ and m₂ are masses
r is the distance between them
From equation (1) it is clear that the force of gravity between two masses is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
So, the gravitational force between two objects is <em><u>directly proportional</u></em> to the product of the masses of the objects

Answer:
1.43 s
Explanation:
The time it takes for the container to reach the ground is determined only by the vertical motion of the container, which is a free-fall motion, so a uniformly accelerated motion with a constant acceleration of g=9.8 m/s^2 towards the ground.
The vertical distance covered by an object in free fall is given by
where
u = 0 is the initial vertical speed
t is the time
a= g = 9.8 m/s^2 is the acceleration
since u=0, it can be rewritten as
And substituting S=10.0 m, we can solve for t, to find the duration of the fall:
