A hollow sphere of negligible mass and radius R is completely filled with a liquid so that its density is rho. You now enlarge t
he sphere so its radius is 2R and completely fill it with the same liquid. What is the density of the enlarged sphere?
1 answer:
The density is still rho. It doesn't change. The density of a substance is the density of the substance. It doesn't depend on how much of it you have.

Answer:
The answer is for your question is :
Explanation:
True
Explanation:
Given:
v₀ = 0 m/s
a = 3 m/s²
t = 4 s
Find: Δx and v
Δx = v₀ t + ½ at²
Δx = (0 m/s) (4 s) + ½ (3 m/s²) (4 s)²
Δx = 24 m
v = at + v₀
v = (3 m/s²) (4 s) + 0 m/s
v = 12 m/s
