Answer:
Explanation:
Given that:
- Area of the plate of capacitor 1= Area of the plate of capacitor 2=A
- separation distance of capacitor 2,
- separation distance of capacitor 1,
- quantity of charge on capacitor 2,
- quantity of charge on capacitor 1,
We know that the Capacitance of a parallel plate capacitor is directly proportional to the area and inversely proportional to the distance of separation.
Mathematically given as:
.....................................(1)
where:
k = relative permittivity of the dielectric material between the plates= 1 for air
From eq. (1)
For capacitor 2:
For capacitor 1:
We know, potential differences across a capacitor is given by:
..........................................(2)
where, Q = charge on the capacitor plates.
for capacitor 2:
& for capacitor 1:
Answer:
The value is
Explanation:
From the question we are told that
The power output from the sun is
The average wavelength of each photon is
Generally the energy of each photon emitted is mathematically represented as
Here h is the Plank's constant with value
c is the speed of light with value
So
=>
Generally the number of photons emitted by the Sun in a second is mathematically represented as
=>
=>
