What is this wave transferring to the tree?
Alexxandr [17]

Option 4 . Energy is transferred to the tree in this wave.

Explanation:

The figure shows that the rope is tied to tree at one end and at the other end a boy is holding it.

Here the boy swings the rope to give it a sudden movement and due to this movement the transverse waves of sinusoidal form are obtained and gets traveled till the tree.

Here the energy used by the boy to give a quick movement to the rope gets transferred till the other end of the rope that means the energy is getting transferred to the tree.

Along with the energy the particles of the way also gets transferred to the tree unless there is an obstacle.

Therefore in this wave energy is transferred to the tree.

What fraction of 2 years is 10 months <br>​
zzz [600]

Answer:

10/24

Simplified: 5/12

Explanation:

Well first, let's convert years into months

1 year = 12 months which means 2 years = 24 months

In fraction form we would write this as 10/24

If the question asks for it to be simplified, then simply

Both 10 and 24 evenly fit 2

Therefore, divide both the numerator and the denominator by 2

10 ÷ 2 / 24 ÷ 2

5/12

This can no longer be simplified
