The force attraction between two objects, does what, as the distance between them increases?

gregori [183]

Decreases

Explanation:

The force of attraction between two objects will decrease as the distance between them increases.

This is in compliance with newtons law of universal gravitation.

The force of attraction between the two bodies is a gravitational force.

According to newton's law of universal gravitation "the force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".

We see that from the last statement, the force of attraction between is inversely proportional to the square of the distances between them.

F ∞ $\frac{1}{r^{2} }$

r is the distance between them.

Which is an example of a conceptual model? a a clay car in a wind tunnel b a model of water temperatures in the oceans c a model

andreyandreev [35.5K]

Answer:

b a model of water temperatures in the oceans

Explanation:

A conceptual model is a means of representing abstract theories, with the aim of helping the audience form mental pictures about the subject being discussed. Most of these models utilize diagrams to help form a better understanding of the subject.

In geothermal explorations, water temperatures can be represented using plane or cross sectional views to demonstrate the varying temperatures of water. This is a useful guidde in the exploration proceess and helps any who read the illustrations to form a better understanding of the process and conditions.
