Answer 1

Hey there, here's your answer.

The length of the slinky is 5 m. However, since the wave travelled to and fro, it started from one end, travelled to the other end, and then returned back to the original end. This makes the total distance travelled by the wave as 5×2 = 10 m.

So, D = 10 m

T = 5 s

v = D/T

= 10/5

= 2 m/s

which is option C.

Therefore the correct answer is C.

Answer 2

Answer:

As the wave moves to and fro so the total distance will be d=2x5=10 m

we have

time (t) = 5 s

hence velocity will be =2 m/s
