The frequency is exactly the rate at which the bug beats its wings.
If that "600" that you mentioned is 600 beats per second, then
THAT's the frequency . . . 600 per second. (600 Hz)
Creating new elements in order to study their properties is definitely pure research.
It has no earthly [known] application, since the elements don't even exist, whereas
for each of the other choices, you've stated the desired application as the reason
for the search.
The correct answer for the question that is being presented above is this one: "D.
Property Electric Field Magnetic Field
<span>Can be produced by moving electric charge X </span>
Have two sides with opposite characteristics X X
Can make metals, such as nickel, iron, and cobalt, into magnets X X
<span>Can be turned on or off with a switch X"</span>
The answer is A. Force is equal to mass x acceleration. The acceleration due to gravity is a constant so multiplying the mass by 2 would double the force.
Answer: R=24.2Ω
Explanation: <u>Power</u> is rate of work being done in an electric circuit. It relates to voltage, current and resistance through the following formulas:
P=V.i
P=R.i²

The resistance of the system is:



R = 24.2Ω
<u>For the device, resistance is 24.2Ω.</u>
