Calculate the weight of the following:
a. a car with a mass of 2500kg

24525 N

Explanation:

The mass of an object is a fundamental property of the object.

The weight of an object is the force of gravity on the object.

This is defined as follows

Weight (W)= mass(m) × weight of a unit mass(g)

( gravitational field intensity = g)

Assuming g= 9.81 ms⁻²,

   W = mg

       = 2500×9.81 = 24525 N

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
