What is an effect of gravity on objects on the surface of earth? check all that apply.

a. objects “fall” toward the center of earth.

b. objects are pulled by earth but do not pull on earth.

c. objects accelerate at a rate of 9.8 m/s each second.

d. objects travel at a rate of 9.8 m/s toward the center of earth.

e. objects are pulled by earth more strongly than they pull on earth.

Answer

A. Objects “fall” toward the center of Earth.

C. Objects accelerate at a rate of 9.8 m/s each second.

Explanation

The so called gravity or gravitational force is the force of attraction between two bodies of given mass. This force is directed towards the center of the two bodies. Each object is attracted to the other with equal force.

Experiments have proved that the objects accelerate towards the center of the earth at a rate of 9.8 m/s per second.

The correct statements about gravity from the choices of this question are:

A. Objects “fall” toward the center of Earth.

C. Objects accelerate at a rate of 9.8 m/s each second.

This is the answer for the written response: Gravity pulls objects toward Earth at a rate of 9.8 m/s2. Weight is the result of gravity's pull on a mass on Earth's surface.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
