Ultrasound with a frequency of 4.077 mhz can be used to produce images of the human body. if the speed of sound in the body is the same (2.31 km/s) as in salt water, what is the wavelength in the body? answer in units of m. 01

The frequency of the ultrasound is (converting in Hz)

while the speed of sound in the body is


We can calculate the wavelength of the ultrasound in the body by using the relationship betwen frequency, wavelength and speed of the wave:

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
