Question

The tip of a tuning fork goes through 400 complete vibrations in a time of 0.570 s .?

Answer 1

See the relationship using ratio.

Explanation:

Using ratio in fraction format.

Let the measure of time be `t`

Let `x` be some constant value

`("count of vibrations")/("count of time") =400/0.570`

So for time `t` we have

`color(green)(("count of vibrations")/("count of time")color(white)("d") ->color(white)("d")400/0.570color(red)(xx1)= ("count of vibrations")/t)`

`color(white)()`

Set `color(red)(1=x/x)`

`color(white)()`

`color(green)(color(white)("ddddddddddddddddd")->color(white)("d")400/0.570color(red)(xx x/x) = ("count of vibrations")/t)`
