yes that's right, thank you very much.
A cardiologist uses an ultrasound scanner with an operating frequency of 3.5 MHz that can detect Doppler frequency shifts as small as 0.1 kHz. What is the smallest flow velocity detectable with this device? Two frequencies are given so I know I have to convert the units but i...
okay, one plane is flying north, straight up and the wind blows the plane east [right]. This is almost similar to pythagorean theorem. My guess is to use x^2 + y^2 = z^2. But im pretty sure there's a formula for this in the first or two chapters of the physics book. Look ...
There is a relationship between momentum and energy KE = 1/2mv^2 p = mv m = p/v KE = 1/2 (p/v)v^2 KE = 1/2 pv From wiki answers The relation between kinetic energy is proportional to the square of velocity. Momentum is directly proportional to velocity. If the momentum of an ...
Find the potential energy when x = 0 or x = -1 Then using this energy then find speed using KE = 1/2mv^2 m = 1 kg
1/4 w=13 What does w equal? Please show all work.
Thank you. I have one more question. 1/4 w=-13
15=y+24 What does y equal? Please show all work.
Those are all good ideas. Thank you!!
