The question is defective. If her acceleration is 2.5 m/s/s, then her speed is 2.5 m FASTER each second, and she will never stop.
Equation: v= (wavelength)(frequency)
V= 3.00 x 10^8 {I think you’ve meant to square it}
Wavelengths = ?
Frequency= 9.23 x 10^7 {I think you’ve meant to square it}
Plug what you have in the formula above:
3.00 x 10^8 = (wavelength)(9.23 x 10^7)
Now DIVIDE 9.23 x 10^7 by both sides.
You will get (3.00 x 10^8) / (9.23 x 10^7)
The wavelength = 3.25 meters
Hope this helps!
Hey !
The anwer is : A.
Because an object is moving at constant speed ( whic is distance/time) when the distance and the time grow directly proportional . (it means when the distance is getting bigger,then the time is getting bigger equally).
The answer is <span> A. Yes, the wave will transfer the energy of Amy's motion to the other end of the rope.</span>
