A pendulum with a period of ones on earth where the acceleration
Answer: τ = 0
Explanation:
At constant angular velocity there is no angular acceleration therefore no torque.
τ = Iα
The third one looks correct to me
I don’t see any picture sorry I wish I can help tho
Answer:

Explanation:
Acceleration is the change in velocity over time.

The object accelerates <em>from</em> 45 meters per second <em>to </em>10 meters per second in 5 seconds. Therefore,

Substitute the values into the formula.

Solve the numerator.

Divide.


The acceleration of the object is -7 meters per square second. The acceleration is negative because the object's velocity decreases and the object slows down.
