Ik this is late
Answer:
Explanation:
initial angular velocity, ωo = 0 rad/s
angular acceleration, α = 30.5 rad/s²
time, t = 9 s
radius, r = 0.120 m
let the velocity is v after time 9 s.
Use first equation of motion for rotational motion
ω = ωo + αt
ω = 0 + 30.5 x 9
ω = 274.5 rad/s
v = rω
v = 0.120 x 274.5
v = 32.94 m/s
Static friction is the friction between an object at rest and the surface on which it is resting on.
Kinetic friction is the friction between a moving object and the surface on which it moves.
Hopefully you understood and this helps :)
Answer:
In an inductive circuit, when frequency increases, the circuit current decreases and vice versa.
Explanation:
Answer:
Initial angular position of the disc is 3 radian
Explanation:
As we know that the angular acceleration of the disc is given as

initial angular speed is given as

now we know that angular displacement of the disc is given as



now we have
