Answer:
As the mass of a white dwarf increases, the pressure must increase to resist gravity. To do this, the electrons must move faster.
Explanation:
A white dwarf also known as degenerate dwarf is a star or an electron degenerate matter and is as massive as the Sun but only about as large in size as planet Earth.
The maximum mass of a white dwarf is about 1.4 times the mass of the Sun.
Also, as the mass of a white dwarf increases, the pressure must increase to resist gravity and to do this, the electrons must move faster.

Answer:
An observation is made. To understand why the phenomenon is occurring, a hypothesis is built up which can be tested by a scientific method. The result of the experiment can be true or false.
If the result false, it implies that the dependent and independent variables are not related and a new experiment must be designed or a modification is required in the experiment.
Thus, even if the result is false, the hypothesis would be useful because conclusions can be drawn from it and next course of action can be defined.

λ =
Explanation:
Using the De Broglie equation, the characteristic wavelength is given by:
λ =
where
h = Planck's constant = Js.
p = momentum
Momentum, p, can be calculated using:
p =
where
m = mass of the electron = kg
E = Energy of the electron = 13.4 keV = J =
J
=> p =
p =
p = kgm/s
Therefore, characteristic wavelength, λ, is:
λ =
λ =
In physics, the characteristic wavelength is the wavelength associated with an object's kinetic energy. It can be determined using the equations for energy, frequency, and wavelength.
In physics, the characteristic wavelength refers to the wavelength associated with a moving object's kinetic energy. The kinetic energy of an object is given by 1/2mv², where m is the mass of the object and v is its speed.
When an object's kinetic energy is known, we can use the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the wave associated with the object, to find the characteristic wavelength.
The equation is rearranged to solve for f, and then the frequency is used to calculate the wavelength using the formula λ = c/f, where λ is the wavelength and c is the speed of light.
By plugging in the given values of the object's mass and speed, you can determine its characteristic wavelength using these equations.
