### What is the speed of an electromagnetic wave that has a frequency of 9.5 109 Hz?

The speed of propagation of an electromagnetic wave (like light,
which is an electromagnetic wave) is nearly the speed of light. It
will actually be the speed of light in a vacuum. But it does travel
a little more slowly depending on the medium through which it is
traveling. (Like air.) The frequency of the electromagnetic wave is
not a determining factor in finding its speed, but will certainly
be a factor in determining its absorption by the medium. A radio
wave of 9.5109 Hz is a really low frequency wave, and generating
and transmitting it would be a pretty piece of engineering.

### What factor determines whether a storm is considered a tropical depression tropical storm or hurricane?

The determining factor is the sustained wind speed. If the
tropical system has sustained winds of less than 39 miles per hour,
then it is a tropical depression. If sustained winds are in the
range of 39 to 73 mph, then it is a tropical storm. If sustained
winds are 74 mph or faster, then it is a hurricane.

###### Asked in Physics

### What will happened to the ke if its velocity is reduced by 12 times?

Kinetic energy is proportional to the square of the speed. If
you reduce the speed by a factor of 12, the kinetic energy will
reduce by a factor of 12 x 12 = 144.
Kinetic energy is proportional to the square of the speed. If you
reduce the speed by a factor of 12, the kinetic energy will reduce
by a factor of 12 x 12 = 144.
