My device will use either radio waves or light waves.
Those are the only EM waves I'm equipped to generate.

If I want to get elegant about it, I may use radio waves with
frequencies around 14.1 MHz, because those can be received
many thousands of miles away.  I know how to build an effective
antenna to radiate at that frequency, and as a licensed ham-radio
operator, I can do it legally.

What role does voltage play in the formation or use of an electromagnet?
Dafna11 [192]
<span>Voltage overcomes the resistance of the electromagnet winding to force a current through that resistance. The field strength is proportional to the coil current. More voltage pushes more current. More voltage builds up the current faster, as well as forcing it to a higher final value. </span>

In a certain process, the energy of the system decreases by 250 kJkJ. The process involves 480 kJkJ of work done on the system.
BigorU [14]

Answer:

-730KJ

Explanation:

According to the first law of thermodynamics;

Let the total energy of the system be ∆E

Let heat be q and let work the w

Since the energy decreases ∆E is negative

Since work is done on the system w= positive

So;

- 250 = 480 + q

q = -250 - 480

q=-730KJ
