Find the velocity and momentum of electron whose kienetic energy equals its rest mass which is 9.1110 power -31?
I rather believe the question ask the kinetic energy equals to rest mass energy of electron. If it would state the figure of rest mass of 9.111 x 10-31 kg = kinetic energy of 9.111 x 10-31 J the unit should be given more clearly. It is given rest mass of 9.111 x 10-31 kg and rest mass energy is calculated by E = mC2 The kinetic energy is Ek = mC2/(1-v2/C2)0.5 - mC2 and for Ek = mC2 It is solving for mC2 = mC2/(1-v2/C2)0.5 - mC2 --> 2mC2 = mC2/(1-v2/C2)0.5 2 = 1/(1-v2/C2)0.5 Solve for v should not be too hard for you. Now, the momentum You must notice that when v is close to speed of light (C), you can't simply use momentum = mv but rather P = mv/(1-v2/c2)0.5 Use v obtained from above to solve for momentum.
E equals mc2 Why is the speed of light squard?
For many reasons. The simplest one is: [mass] times [speed] does not have the dimensions of [energy], but [mass] times [speed squared] has.
Does einsteins equation E equals mc2 apply to black holes?
Yes. It is a conservation law, showing that mass and energy are only different manifestations of the same thing.
What does the E in Enstien's equation?
E = energy e=mc2 (or Engergy (e) equals Mass (m) times the Velocity of Light (c) squared {the speed of light times itself}).
Different theories about stars?
E=mc2
How do you prove e equals mc2?
Einstein's famous equation, E=mc^2, can be proven through the principles of special relativity. The equation shows the equivalence of energy (E) and mass (m) through the speed of light (c) squared, indicating that a small amount of mass can be turned into a large amount of energy. This relationship has been confirmed through various experiments and observations, showing its validity in the understanding of the universe's fundamental laws.
What is mc2 in E equals mc2?
E (Energy) equals M (Mass) times C2 (speed of light square)
Is E equals MC2 a force?
No. E=mc2 is a formula. Energy equals mass times the speed of light squared.
Where did albert Einstein create the formula 3 equals mc2?
The formula is E=mc2.
How did scientists apply Albert Einsteins equation e equals mc2?
Scientists applied Albert Einstein's equation E=mc^2 by using it to understand the relationship between energy and mass. This equation shows that mass can be converted into energy and vice versa, which has led to advancements in nuclear physics, such as in the development of nuclear weapons and nuclear power.
How did Einstein contribute to the field of math?
He discovered "E=Mc2"
Was there any problems with e equals mc2?
no.
Who immortalized E equals MC2?
The formula E=mc^2 was immortalized by Albert Einstein in his theory of special relativity, published in 1905. It describes the equivalence of energy (E) and mass (m) and plays a crucial role in understanding the relationship between matter and energy in physics.
Is E equals mc2 real?
yes it is.
M in E equals mc2?
mass
Who discovered E equals mc2?
The concept of E=MC2 was discovered by Henri Poincare.
What is the sum to e equals mc2?
There is no sum of e=mc2, it is an equation concerning matter and energy. e=mc2 stands for: Energy equals mass times the velocity of light squared. E = M C 2
