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: 7.04 grams
Step-by-step explanation: 2.27x2=4.54 + 2.5 = 7.04 g.
Answer:
middle
Step-by-step explanation:
Irs a little hard to see. But Dilation means the size of the object changed ( increase or decrease) but the shape stays exactly same
Length of JP is 6
Step-by-step explanation:
- Step 1: Find length of JP.
Given that ∠H and ∠J are equal, then sides opposite these equal angles will also be equal.
⇒ PH = JP
⇒ 3x - 6 = x + 2
⇒ 2x = 8
∴ x = 8/2 = 4
⇒ JP = x + 2 = 4 + 2 = 6
