Answer:
Average speed=1.5 m/s
Frequency of pendulum=93.75Hz
Explanation:
We are given
Frequency,
Average wavelength =
Speed of pendulum,
Wavelength,
We have to find the average speed and frequency of pendulum.
We know that
Speed,
Using the formula
Average speed,
Hence, the average speed =1.5m/s
Frequency,
Using the formula
Hence, the frequency of a pendulum=93.75Hz
The displacement ........................
Answer:
Wheel A.
Explanation:
The lesser the moment of inertia, the greater the angular acceleration. Then, the moments of inertia of each wheel are described below:
Wheel A
Wheel B
The wheel A accelerates faster in response to the torque.
