Question

if amplitude and time period of oscillator is 5cm and 16 sec respectively.then time taken by a oscillator to cover 15cm diameter starting from mean position at
$t = 0$
​

Answer 1

Answer:

I am not confirmed but i can give my opinion

Explanation:

Answer:

As we know the time period T is a time taken to complete its one cycle.

And we can draw a one complete cycle in circle form,5cm given in a question is an amplitude which is equal to radius of that considering circle ,to complete its one cycle it took 16sec , by covering half cycle it covers 10 cm diameter(means 180 degree is equal to diameter of that circle, and 90 degree will equal to half diameter(radius) which is 5cm

By covering 180+90 degree it will cover a 10cm+5cm equal to 15cm

20cm(full cycle ) is covered in 16sec then 15cm will cover in 12 sec(find by proportion).

Hence,oscillator will cover 15cm diameter in 12sec.

Am i right???

if right then give me thanks,
