Actually the image that he will see depends of the lens used during the experience. But normally with good light and properly focus it would be possible to see the finger prints like in the image.
Answer:
The Moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis.
Explanation:
The angular momentum is given by the moment of inertia, multiplied by the angular speed of the rotating body:
The angular speed is given by:
Now, we calculate the angular momentum:
The average torque is defined as:
is the angular acceleration, which is defined as:
We have to calculate :
Now, we calculate the angular acceleration:
Finally, we can know the average torque:
1. distance plus direction
displacement
2. 30 m/s northwest, for example
velocity
3. total distance divided by total time
average speed
4. what an object going around a curve at a constant speed is
undergoing
acceleration
5. 30 m/s, for example
speed
6. any non-directional quantity
scalar
