Calculate the gravitational force between a baseball and earth. a baseball has a radius of 0.075 m and a mass of 0.145 kg. earth has a mass of 5.9742•10^24 kg and a radius of 6.3710•10^6 m. assume the baseball is resting on earths surface.

1.424 N

Explanation:

According to Newton's Universal Law of Gravitation:

(1)

Where:

is the gravitational force between the ball and Earth

the Universal Gravitational Constant

is the mass of the ball

is the mass of the Earth

is the distance between the ball and the Earth, being the radius of the ball and the radius of the Earth

So, rewritting (1):

(2)

(3)

Finally:

(4)

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
