Do two objects (two large hunks of lead suspended from two strong strings) exert a gravitational force on each other?

yes
no
not enough information to determine

Yes

Explanation:

Gravitational force is an attractive force exertedn between every object that has mass.

The magnitude of the gravitational force between two objects is given by:

where

G is the gravitational constant

m1, m2 are the masses of the two objects

r the distance between the objects

In this problem, the two objects are two large hunks of lead. Since these objects have mass, they exert an attractive, gravitational force on each other.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
