Answer:
1000
Explanation:
If we model the pencil as a cylinder:
V = π r² h
Or, in terms of diameter:
V = π/4 d² h
If we multiply d and h by 10:
V = π/4 (10 d)² (10 h)
V = 1000 (π/4 d² h)
The volume increases by a factor of 1000.
Answer:
Explanation:
Let m be the mass of cylinder and r be the radius. It is moving with velocity v and angular velocity is ω. Let I be the moment of inertia of the cylinder.
I = 0.5 mr²
Total kinetic energy, T = 0.5 mv² + 0.5 Iω²
T = 0.5 (mv² + 0.5 mr²ω²)
v = rω
So, T = 0.5 (mv² + 0.5 mv²) = 0.75 mv²
Rotational kinetic energy is
R = 0.5 Iω² = 0.5 x 0.5 mr²ω²
R = 0.25 mv²
So, R / T = 0.25 / 0.75 = 1/3
