Frequency (f) in Hz = Wave speed (c) in m/s/Wavelength in m
Wave speed = 60 m/s, Wavelength = 1.2 m
Therefore,
f= 60/1.2 = 50 Hz
40 because it seems to go up by 10's and only by one of the number it goes up
Answer:
301 cm3
Step-by-step explanation:
Formula = V=πr2h
V = 3.14*4*2*12 = 301.44
Nearest whole number = 301 cm3
Answer:
Step-by-step explanation:
Since each trial is independent of the other
no of mistakes he does is binomial with p = 1/3
a) the probability that he makes no mistakes on his first 10 orders but the 11th order is a mistake
=
b) Prob that shanker quits = P(Shankar does I one mistake and Fran does not do the first one)+Prob (Shanker does mistake in the II one while Fran does both right)
=
