Question

7 Calculate the weight of an apple of mass 100 grams

a on the Earth (g = 10 N/kg)
b on the Moon (g = 1.6 N/kg).​

Answer 1

See the anwers below

Step-by-step explanation:

To solve this problem we must understand that the weight of any
`W = 0.1*10\\W = 1 [N]`body is defined as the product of mass by gravitational acceleration. Gravitational acceleration depends on the place in space where a certain body is located.

`W = m*g\\`

where:

W = weight [N]

m = mass = 100 [g] = 0.1 [kg]

g = gravity acceleration [m/s²] or [N/kg]

Now for the Earth

`W =m*g\\W =0.1*10\\W = 1[N]`

For the Moon

`W = m*g\\W =0.1*1.6\\W = 0.16 [N]`
