Answer:
q = C V charge on 1 capacitor
q = 1 * 10E-6 * 110 = 1.1 * 10E-4 C per capacitor
N = Q / q = 1 / 1.1 * 10E-4 = 9091 capacitors
V = I · R
Voltage = (current) · (Resistance)
Voltage = (250 A) · (2.09 x 10⁴)
Voltage = 5,225,000 volts .
I may be out of line here, but I'm pretty sure
that the resistance is 2.09 x 10⁻⁴ .
Then
Voltage = 0.05225 volt (not 5 million and something)
Answer:
metre for length and the kilogram for Mass
Answer:
x = (mg-f)/k
Explanation:
there are three forces acting on cylinder in a tube, (1) force due to spring = -kx (2) force due to friction = f (3) force due to gravity.
we want to calculate an instant when all three forces acting on mass cancel and there is 0 net force and cylinder momentiraly comes to stop.
let's write it in mathematics.
kx+f-mg=0 (kx is positive because it is upwards and that is how we have setup our coordinate axis in this problem).
solving for x gives.
x = (mg-f)/k.
Answer:
Magnetic Field Strength
Explanation:
The effect of the splitting of the spectral lines of an atom into several of its components when a static magnetic field is present is referred to as Zeeman Effect.
The spectral lines here corresponds to the various discrete energy levels in the sun at which the emission and absorption of the different energy levels of the sun occurs.
The splitting of the spectral lines occurs due to the presence of the strong magnetic field on the surface of the sun.
Thus the Zeeman Effect is used to measure the magnetic field strength on the sun's surface.
