Answer:
0.011 N-m
Explanation:
Given that
The mass of a solid cylinder, m = 30 kg
The radius of the cylinder, r = 0.18 m
The acceleration of the cylinder,
It rotates about an axis through its center. We need to find the torque acting on the cylinder. The formula for the torque is given by :
Where
I is the moment of inertia of the cylinder,
For cylinder,
So,
So, the required torque on the cylinder is 0.011 N-m.
Answer:
A. the words "work" and "energy" are interchangeable.
Explanation:
Work and kinetic energy are interchangeable, so they are the same, ie. they have the same units. Your work can give kinetic energy to a body and a body with kinetic energy can produce work

It will take 20 seconds for the car to attain a speed of 34 m/s
Explanation:
- Acceleration of an object is given by a = velocity/time.
- Here, acceleration of the car = 1.7 m/s² and velocity = 34 m/s. Using these, find time.
- Time = velocity/acceleration
= 34/1.7 = 20 s
So it takes 20 seconds to attain a speed of 34 m/s
