Question

C) A sample of substance of volume 10 cm3 was brought back to Earth from the Moon.

The weight of the sample on the Moon was 0.13 N. The gravitational field strength
on the Moon is 1.6 N kg-1.
(1)
Calculate the density of the sample.

Answer 1

8125

Step-by-step explanation:

`P=0,13 N\\a=1,6 N/kg\\m=P/a=0,13/1,6=0,08125\\V=10(cm)^(3) =10^(-5) meters^(3) \\p=m/V=0,08125/10^(-5) =0,08125*100000=8125kg/meters^(3)`
