The magnitude of acceleration, is the same. You are probably thinking about centripetal force F=mv^2/r. But the question asks about the centripetal acceleration ac=v^2/r of the ride. The rides velocity and radius remains constant so the magnitude of acceleration of the ride is the same for both adult and child

A source produces 20 crests and 20 troughs in 4 seconds. The second crest is 3 cm away from the first crest.Calculate :

sineoko [7]

Answer:

Solution given:

No of waves[N] =20crests & 20 troughs

=20waves

Time[T]=4seconds

distance[d]=3cm=0.03m

Now

<u>Wave</u><u> </u><u>length</u><u>=</u>3cm=3 × ${10}^{ - 2}m$

<u>Frequency</u>= $\frac{No of waves}{time}$

= $\frac{20}{4}$ =5Hertz

and

Wave speed:wave length×frequency=3 × ${10}^{ - 2}m$ ×5=1.5 × ${10}^{ - 1} \tt{ {ms}^{ - 1}}$ .
