An object rotates with period of 10s.how many revolutions will it make in25s

Answers

Answer 1

Answer:

2¹/2

Explanation:

if the revolution is in 10 seconds the R,=Total time÷time of the revolution

Answer 2

Answer:

The object will make [tex]2\frac{1}{2}[/tex]  (2.5) revolutions in 25s.

This indicates that it will revolve through two full revolutions before rotating a third time in the opposite direction.

Explanation:

A rotational period of 10 seconds indicates that an object completes one full rotation every 10 seconds. The object's frequency is therefore 1/10 Hz, or 0.1 Hz. We must apply the calculation to determine how many revolutions it will complete in 25 seconds:

Number of revolutions = frequency x time passed

We are informed that 25 seconds have passed. Using the following formula, we can determine the frequency:

Frequency = 1 / period.

The frequency is because the period is 10 seconds:

Frequency equals 1/10, or 0.1 Hz.

Now we can calculate the number of revolutions using the formula above:

Number of revolutions = (25 s) x (0.1 Hz) = 2.5 revolutions

It takes 10 seconds for the first complete revolution, another 10 seconds for the second full revolution, and 5 seconds for the final half revolution.

In other words, the object starts at its starting location, rotates a whole anticlockwise revolution, another full anticlockwise revolution, and then eventually rotates a further half anticlockwise revolution before returning to its initial position. As a result, the item in this instance rotates in the opposite direction of clockwise.

As a result, in 25 seconds, the object will complete 2.5 revolutions.
