Question
When two simple harmonic motions of same periods, same amplitude, having phase difference of 3
/2, and at right angles to each other are super imposed, the resultant wave form is a
- circle
- decreases by 0.61 ms-1
- increases by 61 ms-1
- decreases by 61 ms-1
The correct answer is: circle
The increase of pressure does not change the velocity of sound. When the temperature increases by 10C, the velocity of sound increases roguly by 0.6 ms-1. (Vt = V0 + 0.6 t).
\ x2 + y2 = a2.
