That would be a maximum of 4 atoms
Answer:
Solution given:
No of waves[N] =20crests & 20 troughs
=20waves
Time[T]=4seconds
distance[d]=3cm=0.03m
Now
<u>Wave</u><u> </u><u>length</u><u>=</u>3cm=3 × 
<u>Frequency</u>=
=
=5Hertz
and
Wave speed:wave length×frequency=3 ×
×5=1.5 ×
.
It's not that the laws of motion are any different on Earth than in space. But Earth's gravitational field has such an overwhelming force it masks their precise effects. And gravity is integral to all sorts of phenomena that we take for granted.
Faraday discovered that a current could be induced in a solenoid (a coil of wire) when "<span>a magnetized rod is being moved through the coil"

First convert the speed of sound from meters/second to miles/second:

Then the time it takes for the sound to travel 20 miles is
