Hii: ) anyone able to with this question? ( it’s in the pic above)
you : ) !

4.0s

Explanation:

The period of the pendulum is the time taken for it to complete 1 full oscillation. This means that the pendulum moves this way for it to be 1 oscillation:

P ➟ Q ➟ R ➟ Q ➟ P

Since the pendulum only moved back to midpoint Q and not back to P, it has completed less than 1 oscillation.

Let each movement to the next section be 1 unit.

So 1 oscillation - 4units

In this case, the pendulum moved 3 units.

3 units ----- 3s

1 unit ----- 3÷3

1 unit ----- 1s

Thus 1 full oscillation would take 4(1)= 4s

Therefore, period of pendulum= 4s.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

happy to

pls mark as brainliest

explanation:

could i give you a exaplo that could you?
