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...
