Answer:
no motion means no velocity, so the y values willl always be 0 as ur time (x) value increses
Explanation:
Answer:
I think then answer for this question is number c. the South pole
Answer:
Remains the same
Explanation:
The speed of waves of higher and lower frequency both will be same.
the speed of sound in a medium is constant and independent of it's frequency. Moreover, when the frequency changes wavelength changes accordingly, such that their product remains constant.
we know that
υ×λ = constant = velocity
υ= frequency
λ= wavelength.
I think you should hold a stretch for 10-30 seconds
