Answer:
80m/s
Explanation:
to find it you have to work it out by using the formula distance divided by speed to find time.
Answer:
Sound waves are pushed closer together, decreasing wavelength
and increasing frequency.
Answer:
there are go fella hope u understood
The input work = Force x distance
So I/P = 45 x 1.5 = 67.5 N.m
The output work = Force x distance
So, O/P = 87.6 x 0.4 = 35.04 N.m
Efficiency = (output work / Inputwork) x 100
= ( 35.04/67.5) x100
Efficiency = 51.91 %
A funnel shaped cloud is called a funnel cloud.
If it touches the ground it is called a tornado.
