Answer:
2.05 kgm²/s
Explanation:
I = moment of inertia of cylinder = 0.016 kgm²
r = radius of the cylinder = 6 cm = 0.06 m
v = linear speed of the cylinder = 7.7 m/s
w = angular speed of cylinder
Using the equation
v = r w
7.7 = (0.06) w
w = 128.33 rad/s
Magnitude of angular momentum of the cylinder is given as
L = I w
L = (0.016) (128.33)
L = 2.05 kgm²/s
Answer:
α=9.42 rad/s T= 0.014 rad/s
Explanation:
Low speed= Wi=3 rps = 3*2*π rad/s= 6π rad/sec
Medium speed= Wf= 9 rps= 9*2*π rad/sec= 18 rad/sec
time= t= 4 sec
Angular acceleration=α=
⇒α=(18 π - 6 π)/4
⇒α=9.42 rad/s
b).
Rotational inertia= I = 1.5*10^-3 kg-m^2
Net torque= T = I*α = (1.5*10^-3) * (9.42) rad/s^2
⇒T= 0.014 rad/s^2
Answer:
They are temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness. Together, these components describe the weather at any given time.
Your speed is one of the only factors that has an effect on both your thinking distance and braking distance. Put simply, the faster you are going, the greater the distance travelled before you apply the brakes (thinking distance) and the vehicle comes to a complete stop (braking distance).
Radio waves are the waves with the lowest energy in the electromagnetic spectrum. X-rays and gamma rays are the highest. Sound is not part of the electromagnetic spectrum.
