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).

See the anwers below

Explanation:

To solve this problem we must understand that the weight of anybody is defined as the product of mass by gravitational acceleration. Gravitational acceleration depends on the place in space where a certain body is located.

where:

W = weight [N]

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

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

Now for the Earth

For the Moon

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
