Answer:
Check the explanation
Explanation:
The beat frequency is
df = f2 - f1
the wavelength is
lamda1 = (v/f1)
and lamda2 = (v/f2)
where v = 340 m/s,f1 = 25.0 kHz and f2 = 20.0 kHz
Answer: 2.4 watts
Explanation:
Work done by horse = 910J
Time = 380 seconds
Power output of the horse = ?
Recall that power is the rate of doing work. Thus, power is workdone divided by time taken.
i.e Power = (work/time)
Power = 910J/380seconds
Power = 2.395 watts (rounded to two significant figures as 2.4 watts)
Thus, the power output of the horse is 2.4 watts
Answer:
A hurricane starts to form when warm air rises and then that warm air turns into cooler air. After a while of this happening large clouds and thunderstorms are made. The clouds and thunderstorms keep growing and rotating from earth's Coriolis Effect. Then a hurricane forms.
