In some applications of ultrasound, such as its use on cranial tissues, large reflections from the surrounding bones can produce standing waves. this is of concern because the large pressure amplitude in an antinode can damage tissues. for a frequency of 1.0 mhz, what is the distance between antinodes in tissue?
a. 0.38 mm
b. 0.75 mm
c. 1.5 mm
d. 3.0 mm

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Avalue that describes how heavy an object is and is related to the force of gravity is

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
