Answer:
1300.80988 Nm
730.79206 kgm²
Explanation:
m = Mass of ladder = 23.8 kg
g = Acceleration due to gravity = 9.81 m/s²
L = Length of ladder = 9.08 m
F = Applied force = 260 N
= Angular acceleration = 1.78 rad/s²
I = Moment of inertia
Weight is given by
The center of gravity of the ladder lies at the center of the ladder
Torque will be
The net torque acting on the ladder is 1300.80988 Nm
Torque is also given by
The moment of inertia of the ladder is 730.79206 kgm²
Population growth is based on four fundamental factors - Birth rate, death rate, immigration and emigration.
Answer:
(D) the sphere
Explanation:
The bodies given are Disk and Solid sphere (uniform sphere)
Moment of inertia of the bodies are
I(disk) =
I(sphere) =
Since the moment of inertia of sphere is less than that of disk, therefore sphere will reach the bottom first.
