C look at how many oxygen, nitrogen’s, and hydrogens there are
Answer:
A. Moving the mass from Point C to B, although it involves a greater distance, requires less force to do the same amount of work.
Explanation:
The amount of work will be the same either way. By going from C to B, the mover will exert less force over a greater distance, which is easier than exerting a greater force over a shorter distance.
Answer: Conversion of 9.83 m/s with a radius of 0.85 m into rotations per minute (rpm) is
.
Explanation:
Given: Speed = 9.83 m/s
Convert m/s into m/minute as follows.

Radius = 0.85 m
Now, rotations take place in circular motion. So, the circumference of a circle is
.
Therefore, circumference is calculated as follows.

Formula used to calculate rotations per minute (rpm) are as follows.

Thus, we can conclude that conversion of 9.83 m/s with a radius of 0.85 m into rotations per minute (rpm) is
.
Answer:increases
Explanation:
If we are going upward in an elevator from the ground floor to the top floor then it indicates that your distance from the center of the earth is increasing while the time period remains the same.
If the radial distance is increased then the tangential velocity of the object must be increased because the time period is the same.
This can be best explained by taking an example of a car moving in a circle of radius r. If radial is increased for the same period then the car has to travel at a higher velocity to make in time.
