Which change will cause the gravitational force between a baseball and a soccer ball to increase ? check all that apply moving the balls closer together moving the balls further apart wrapping the soccer ball in layers of duct tape using a baseball with a thinner leather removing the outer layer of the baseball putting the baseball in a plastic case

Explanation :

We know that the gravitational force between two objects is given by :

where,

G is universal gravitational constant.

and are the masses of two objects.

r is the distance between them

i.e.

and

So, the correct options are :

(1) Moving the balls closer together. The distance decreases and force increases.

(3) Wrapping the soccer ball in layers of duct tape will also increase force because the mass will increase.

(5) Similarly, putting the baseball in a plastic case will increase mass and hence force increases.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
