If an object has a mass of 20 kg, what is the force of gravity acting on it on earth? a. 32.67 n b. 2.04 kg c. 1.96 kg d. 196 n

D. 196 N

Explanation:

The force of gravity acting on an object located at the Earth's surface is given by:

where

m is the mass of the object

g is the acceleration due to gravity

In this problem:

- m=20 kg is the mass of the object

- g = 9.81 m/s^2 is the acceleration due to gravity at Earth's surface

Substituting these data into the formula, we get

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
