Answer:
As with any wave the speed of sound depends on the medium in which it is propagating.
Explanation:
First of all, that equation is not correct, which may be the reason
that you're having trouble assigning units to the quantities.
Power is defined as [energy / time], so [Energy] = [ power x time ],
and
[Time] = [ energy / power ].
Unit-wise, these equations are correct just as they appear here,
with no proportionality constants or conversion factors, when ...
[ Power ] = watts
[ Energy ] = joules
[ Time ] = seconds .
Relation between Electric and magnetic fields. I've read that both the electric and magnetic field vectors are perpendicular to each other in an electromagnetic wave. Passing steady current through a straight conductor shows some magnetic flux (because most of the energy is wasted into outer space as magnetic lines).
Hopefully this will help you.
Because plastic and rubber are insulators.
