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?
prove:E=mc2
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.
