Answer:
The moment of inertia is 0.7500 kg-m².
Explanation:
Given that,
Mass = 2.2 kg
Distance = 0.49 m
If the length is 1.1 m
We need to calculate the moment of inertia
Using formula of moment of inertia
Where, m = mass of rod
l = length of rod
x = distance from its center
Put the value into the formula
Hence, The moment of inertia is 0.7500 kg-m².
Answer:
t = 224 s
Explanation:
given,
length of container = 15 cm = 0.15 m
diameter of spherical particle = 2.5 μm
mass of particle = 1.9 x 10⁻¹⁴ kg
viscosity of air = μ = 1.18 x 10⁻⁵ kg/m.s
time taken by the particle to stop = ?
radius of particle = 2.5/2 = 1.25 μm
volume of particle =
=
Density =
Density =
ρ = 2322 kg/m³
terminal velocity
v_t = 6693 x 10⁻⁷ m/s
t = 224 s
