If this is about simple machines the answer is: Inclined plane
First:
5 cm = 0,05 m
Now, the formula:
F = k * (qq') / r²
Replacing:
F = 9x10⁹ * (55x10⁸ * 1x10⁷) / 0,05²
F = 9x10⁹ * (5,5x10¹⁶ / 2,5x10⁻³)
F = 9x10⁹ * 2,2x10¹⁹
F = 1,98x10²⁹
The force between the charges is 1,98x10²⁹ Newtons.
The electromagnetic waves with the greatest frequency
on the spectrum are the ones we call "gamma rays".
The electromagnetic waves with the lowest frequency
on the spectrum are the ones we call "radio waves".
Answer:8 *10 ^-15 N= 8 fN
Explanation: In order to solve this we have take into account the following expression:
V=E*d the potential is equal to electric field multiply the separation between the plates.
The we have
E=V/d= 500 V/0.01 m=50000 N/C
then the force is given by
F=e*E = 1.6 * 10 ^-19 C*50000 N/C=8*10^-15 N
Answer:
Fn = 246.2 N
Explanation:
I assume you meant meters per second squared for acceleration of the elevator. All you have to after your picture/free-body diagram is made is add the forces together. You could do this by finding them separately like I did or use Fn = m(Fg + Fe). I just calculated magnitude and didn't worry about signs.
