Explain the difference between mass and weight and how they are measured.

Mass:

1) Definition : Mass is the quantity of matter possessed by the body.

2) Quantity : Mass is a scalar quantity

3) Measurement: Mass is measured by ordinary balance

4) Unit : Unit of mass is kilograms in SI units.

5) Formula : m = W/g

Weight:

1) Definition: The gravitational force of attraction is called weight.

2) Quantity : Weight is a vector quantity.

3) Measurement : It is measured by spring balance

4) Unit : Unit of Weight is Newton in SI units.

5) Formula : W = mg  [Where m is mass and g is acceleration due to gravity]

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
