MV stands for Mega-volt.
It is a unit of electric potential.
1 MV = 1000000 volts.


1 MeV stands for million electron volts.
It is a unit of energy.
1 MeV = 1.60217653 x 10-13 Joules.

In any measurement, a capital 'M' prior to that unit of measure means "mega" or "one million." A file of size one megabytes or M-byte, for example, is a file of size one million bytes.

A small 'm' means "milli" or "one thousandth of a." A "mm" is a milli-meter is one-thousandth of a meter, one mg is one milligram is a one-thousandth of a gram, etc.

Thus, a MeV is a million electron volts of energy, and a meV is one-thousandth of an electron volt of energy.

What is the difference between GeV and MeV electron bolts?

What is the difference between toeque and momentum?

Torque is vector energy e.g FxD and momentum is the product of mass and speed p= mv or velocity P=mV. Torque is a vector energy and Momentum is energy per unit speed, a vector or a scalar, W/c = Momentum.

How many hydrogens do you have to fuse together to make one helium?

None. Hydrogen and Helium are base elements.Helium is helium.Chemically yes, but with Nuclear Physics in stars:H + H --> D + e+ + v + 0.42 MeV, H + H --> D + e+ + v + 0.42 MeV, D + D --> He3 + n + 3.27 MeV (50%)H + H --> D + e+ + v + 0.42 MeV, H + H --> D + e+ + v + 0.42 MeV, D + D --> He3 + H + 4.03 MeV (50%)H + H --> D + e+ + v + 0.42 MeV, H + D --> He3 + gamma photon + 5.49 MeV, H + H --> D + e+ + v + 0.42 MeV, H + D --> He3 + gamma photon + 5.49 MeV, He3 + He3 --> He + H + H + 12.86 MeV (100%)H + D --> He3 + gamma photon + 5.49 MeV (100%)D + D --> He3 + n + 3.27 MeV (50%)D + D --> He3 + H + 4.03 MeV (50%)D + T --> He + n + 17.59 MeV (100%)T + T --> He + n + n + 11.33 MeV (100%)Four or two, depending on the kind of hydrogen isotope you are burning. As you can see in the equations above burning four ordinary atoms of hydrogen to ordinary helium is a complicated and slow process compared to burning two atoms of various isotopes of hydrogen, however a star has such tiny quantities of deuterium and tritium that depending on them for fusion helps little.


How could you tell the difference between cobalt 60 a sample of radon 222 and a sample of bismuth 83?

Cobalt-60 has two gamma photopeaks at 1.17 MeV and 1.33 MeV. Radon-222 is an alpha emitter. Bismuth-83 is not a valid isotope. 83 is the atomic number of bismuth, but you need to know the atomic mass number. The nuclide with the longest half-life is bismuth-208, and it decays by beta+ decay.
