Two spherical objects have a combined mass of 190 kg . the gravitational attraction between them is 8.27×10−6 n when their centers are 19.0 cm apart.1.) what is the mass of the heavier object? (kg)
2.) what is the mass of the lighter object? (kg)

Explanation:

It is given that,

Let are the masses of two objects such that,

............(1)

Force between them,

Distance between masses, d = 19 cm = 0.19 m

The gravitational force between two masses is given by :

.............(2)

On solving equation (1) and (2),

Mass of heavier object,

Mass of lighter object,

Hence, this is the required solution.

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

it has to be b, about 97 percent.
