A boat at anchor is rocked by waves whose crests are `100 m` apart and whose speed is `25 m//s`. These waves reach the boat once every :

A

`5.0`sec

B

`4.0`sec

C

`2.0`sec

D

`0.25`sec

Text Solution

Verified by Experts

The correct Answer is:
A
`v=nalmabdaimpliesn=(25)/(100)=(1)/(4)`, `T=(1)/(n)=(1)/(0.25)=4s`
