Question

1.0. A body has a moss 5 kg, what does it mean? How

Answer 1

Let's see.

A body has a mass of 5kg that means it's weight on earth is about 49N since,

$F_g=m\cdot g=5kg\cdot 9.8\frac{m}{s^2}=49N$

The mass of a body is measured using balance device.

One second is a time interval in which 1 second passes. It is also the base unit of time.

Hope this helps.
