Oh I see, do you think I need to memorize all of the prefixes?

Thanks!

@haruspex I'm sorry for the late reply, I believe that the equation which relates the torque to I and the angular acceleration is T = Ia. And since the linear acceleration is that of a tangent to the drum, linear acceleration = a/r. I combine those to get the equation T = (Ia)/r. Is this correct?

Homework Statement:: Hello, I have a simple question which goes like this: Medical ultrasound waves travel at about 1392.8 m/s in soft tissue. Higher frequencies provide clearer images but don't penetrate to deeper organs. Find the wavelengths (mm) of 1.7-MHz ultrasound used in fetal imaging...

@haruspex I can show you the the diagram of what happen as well if you want

Oh I see, now I understand it a little bit more, thanks for the help! @haruspex
