An object near the earth's surface is in a state of free fall. the object is experiencing a downward force of 170 n. what is the mass of the object?

Weight of the object is 17

Explanation:

The force acting in the downward direction is newton.

Since the object is travelling in the downward direction, the acceleration due to gravity is applicable

Hence "g" is acting downward

We know that force is equal to the product of mass and acceleration. Here is this case "acceleration due to gravity"

So,

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
