Answer: The valve move 120° per second.

Explanation:

Since we have given a figure.

There is period of 2π in 3 seconds.

That means, it covers 2π degrees in every 3 seconds.

As we need to find the number of degrees the valve move per seconds.

We will use "Unitary method":

In every 3 seconds , Number of degrees would be 360°.

So, in every 1 second, Number of degrees would be


(360^\circ)/(3)=120^\circ

Hence, The valve move 120° per second.
