What is the value, in meters per second squared, of the acceleration of
gravity?

The value, in meters per second squared, of the acceleration of gravity is 9.81.

Explanation:

Gravitational acceleration, the acceleration caused by the gravitational attraction of massive bodies in general.

Gravity is 9.81 meters per second squared as the size of earth and distance we are from its center.

The value 9.81 meters per second squared means objects on earth will accelerate 9.81 meters every second,due to pull of gravity.

Throughout space gravity is constant only acceleration due to gravity changes and 9.81 is the value that we are talking about.

Formula to calculate is g = GM/r 2,

where r and m indicates mass and radius of earth.

the answer is a and have a great day

b.

the accuracy of the data.
