A.gold is the answer. As it's density is 19.32 grams per cubic centimeter which is lot more than the other substances.
<span>Density can be calculated and found by dividing the sample's mass by its volume. D=m/v</span>
C Weight is the gravitational pull on an object
A :-) for this question , we should apply
F = ma
Given - F = 12 N
a = 0.20 m/s^2
Solution -
F = ma
12 = m x 0.20
m = 12 by 0.20
m = 60 kg
.:. The mass is 60 kg.
