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).
All frequencies of light in hertz are in between

and

Light with a lower frequency than 4 * 10^14 Hz, are called infrared and can't be seen by human eye. Light with a higher frequency than 8 * 10^14 Hz, are called ultraviolet and can't bee seen by human eye.
Therefore, the maximum frequency of visible light in Hz, is
8 * 10^14 Hz
Answer:
Speed = 2.25 m/s
Explanation:
(Assume a running step is 1.5 m long)
Given the following data;
Energy = 0.6J
Power = 61 Watts
Mass = 68 kg
To find how fast the person running;
First of all, we would determine the total mechanical energy being dissipated by the person.
Total energy = 0.6 * 68
Total energy = 40.8 Joules
Next, we find the time;
Energy = power * time
40.8 = 61 * time
Time = 61/40.8
Time = 1.5 seconds
Finally, to find the speed;
Speed = distance/time
Speed = number of steps * time
Speed = 1.5 * 1.5
Speed = 2.25 m/s
Advantage equals 0.1, mate
1) advantage of plane: 5 divided by 25 = 0.2
2) advantage of fixed pulleys = 0
3) advantage of movable pulley = 0.5
4) and you multiply 0.2 and 0.5 = 0.1
to lift 1kg you don't need force 10N, you will just need 1N
I think the correct answer would be processing time. The time of fifteen minutes describes how long the whole operation was done or how long is the whole processing of drilling. Hope this answers the question. Have a nice day.
