an ultrasound pulse used in medical imaging has a frequency of 5 mhz and a pulse width of 0.5 us. ap- proximately how many oscillations of the sound wave occur in the pulse? the number of oscillations is sometimes called the quality, q, of the pulse. a pulse with little damping has q 1, whereas a heavily damped pulse has e 1. is the ultrasound pulse heavily damped?

At the frequency of 5 MHz, the period of the oscillations is 1/5meg. That's a period of 1/5 microsecond.

There are 5 full cycles in one full microsecond, and there are 2.5 full cycles in a 0.5 us pulse.

You'll have to decide for yourself how damped a pulse of 2.5 cycles is, because the parameters of the definition are corrupted in the question.

which three statements are true about all alloys?

i would say
