Question

Q3. Amna is an astronaut. She measured her body mass using a bathroom scale. See the reading on the scale and note it down using the correct units. Body mass: _____________ Unit: _____________ What is Amna’s weight on Earth? (Hint: Earth’s gravity pulls on each kg with a force of 10N) __________________________________________________________________________ A second astronaut has a weight of 600N on Earth. What would be his body mass on Earth?

Answer 1

Body mass of Amma = 700 N

Weight of second astronaut = 60 kg

Explanation:

Mass of second astronaut on Earth = 600 N

Earth's gravity pulls on each kg with a force of 10N.

So weight of the second astronaut = 600 / 10 = 60 kg.

Amma's reading on the bathroom scale is not given in the question. Assuming it shows 70 kg, then the body mass of Amma will be 70*10 = 700 N.

If given a different reading, you can following the same steps to find the body mass of Amma. Unit is Newtons.
