The amount of charge on each plate is equal to 0.9 Coulombs.
<u>Given the following data:</u>
To calculate the amount of charge on each plate:
<h3>The formula for work done.</h3>
Mathematically, work done in moving a charge is given by this formula:
<u>Note:</u> The work done by an external force equals the change in potential energy for the charges that were moved.
But,
Now, the work done becomes:
Making q the subject of formula, we have:
Charge, q = 0.9 Coulombs.

the <u>average powe</u><u>r</u> output of the sun is <u>3.8 × </u><u> W</u> given that about 1350 w/m2 reaches the upper atmosphere of the earth.
As we know intensity falling over a surface is equal to Energy falling per unit area per unit volume.
I =
Since Power is equal to energy/time
I = power/area
or
Power = Intensity × area
Now, Distance from Sun to Earth , r = 149.6 × m
So, Surface area of the sphere of radius is:
A = 4 π
= 4 × 3.14 × (149.6 × )²
= 2.81 × m²
Thus Average Power output of the sun will be:
P = 1350 × 2.81 ×
= 3.7935 ×
P = 3.8 × W
So the average power output of the sun is 3.8 × W.

Answer:
The total resistance in a parallel circuit is always less than any of the branch resistances. Adding more parallel resistances to the paths causes the total resistance in the circuit to decrease. As you add more and more branches to the circuit the total current will increase because Ohm's Law states that the lower the resistance, the higher the current.

Answer:
The wavelength of the emitted photon is 413.6 nm
Explanation:
Given;
energy of the emitted photon, E = 3 eV = 3 x 1.602 x 10⁻¹⁹ J
speed of light, c = 3 x 10⁸ m/s
The energy of the emitted photon is given by;
E = hf
where;
h is Planck's constant = 6.626 x 10⁻³⁴ J/s
f is the frequency of the light = c / λ
λ is the wavelength
Therefore, the wavelength of the emitted photon is 413.6 nm
The answer is 125 Joules
The first thing to take note of is the work equation: W=F×D
Since we already have our force and our distance that will help make this problem easier.
So, W=25*5
W=125
Therefore, our answer is 125 Joules since work is measured in joules
