Aliter is the same as a cubic meter.
a. true
b. false

The correct answer is B. False

Explanation:

Liter and cubic meter are two different units mainly used for measuring volume (space occupied by a substance). However, a liter and a cubic meter are equivalent to different amounts of substances. Indeed, one cubic meter is equivalent to 1000 liters, this implies a cubic meter represents a larger volume of a substance than a liter as there are 1000 liters in just one cubic meter. This implies a liter is not the same as a cubic meter as these units measure different volumes.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
