To solve this problem we will use the concept related to electrons in a box which determines the energy of an electron in that state.
Mathematically this expression is given by,
Where,
m = mass of an electron
h = Planck's constant
n = is the integer number of the eigenstate
L = Quantum well width
The change in energy must be given in state 1 and 2, therefore
Replacing we have:
Therefore the correct answer is C.
if one of the charge is doubled, the electric potential energy would be doubled too
Albedo is how much sunlight reflects off the surface of the Earth. More albedo could mean a number of things. Higher temps, more photochemical smog, it all depends on where the albedo is occurring.
A chemotroph gains its energy by eating something else
As per Einstein's theory of relativity, the closer the clock is to the source of gravitation, the slower the time passes. Clocks close to massive bodies slow down. The time difference between two events will be very large. Time difference between two clock ticks will take extremely large amount of period.
it is confirmed by tests of general relativity.
Black holes are strongly densed matter. the gravitational attraction influences the clock ticks. Atomic clocks run a little faster on aeroplanes , away from surface of earth. Very close to back hole, where attraction and gravity is extremely high, clock ticks so slow that time can be thought of as stopped...
