The moment of inertia of a spherical shell is I = mr²
If two spheres have the same moment of inertia, then
I₁ = I₂
m₁(r₁)² = m₂(r₂)²
Solve for the second mass:
m₂ = m₁ (r₁/r₂)²
Given m₁ = 1 kg, r₁ = 2 m, r₂ = 1m,
m₂ = (1 kg) (2 m / 1 m)² = 4 kg
Answer: mutiply x by itself to get y
Step-by-step explanation:
Answer:
100% equals to 1 because 75% = 0.75 so then just add 25% = 0.25 so 0.25+0.75=1
