An unstable particle at rest breaks into two fragments of unequal mass. The mass of the lighter fragment is 1.75 MeV/c2 and that of the heavier particle is 3.50 MeV/c2: The lighter fragment has a speed of 0.956 c after the breakup. (i) What is the speed of the heavier fragment? Express your answer as a fraction of c, the waythe speed of the lighter fragment is expressed above.(ii) What is the kinetic energy of the lighter fragment, in electron volts (eV)?(iii) What is the speed of the lighter fragment as seen by the heavier fragment? Express your answer as a fraction of c.

How much work (in eV) does it take to move 12 protons though a 4V potential difference?

What are the energy equivalents (in MeV) of the mass of (a) an electron, (b) a proton, (c) a hydrogen atom, and (d) a helium atom?

If the potential energy of the electron equal -4.3 ev , what is its mass ?

A proton of energy 10 MeV is moving in Pb. How much energy does it lose in a collision with an electron? How many collisions are required to completely stop it? Solution: Energy lost in a single collision with an electron = E = 0.02179 MeV = 21.79 keV Total number of collisions required to completely stop proton = = 459 collisions

Recently scientists have discovered how to contain an anti-hydrogen atom, an element made of an anti-proton and an anti-electron, both of which have the same mass as their real matter counterparts. When anti-matter and matter collide, they annihilate each other and form pure energy. How much energy is given off when anti-hydrogen and hydrogen atom collide?   Question 13 options:   1260 MeV   1880 MeV   720 MeV   940 MeV

What is the speed of a beam of electrons (in SI units) that go undeflected when passing through crossed electric and magnetic fields of magnitude (5.07x10^0)x104 V/m and (4.270x10^0)x10-3 T, respectively? Give your answer to 3 sf.

The mass of an electron is 9.109 381 88 * 10-31 kg.To eight significant figures, find the following for the given electron kinetic energy: (a) gama and (b) b for K =1.000 000 0 keV, (c) g and (d) b for K = 1.000 000 0 MeV, and then (e) g and (f) b forK = 1.000 000 0 GeV.

If a proton and electron are released when they are 2.0  m apart, find the initial acceleration of electron (in m/s2). The answer (in fundamental SI unit) is ___________ (type the numeric value only)
