1. What is the kinetic energy of
(a) an electron having a momentum of 40 GeV/c ?
(b) a proton having a mo- mentum of 40 GeV/c ?
2. A muon has a mass of 106 MeV/c 2. Calculate the speed, momentum, and total energy of a 200-MeV muon.
3. The reaction 2H + 2H S n + 3He (where n is a neu- tron) is one of the reactions useful for producing energy through nuclear fusion.
(a) Assume the deuterium nuclei (2H) are at rest and use the atomic mass units of the masses in Appendix 8 to calculate the mass-energy imbalance in this reaction. (Note: You can use atomic masses for this calculation, because the electron masses cancel out.) This amount of en- ergy is given up when this nuclear reaction occurs.
(b) What percentage of the initial rest energy is given up?
A charge of uniform density (0.80 nC/m) is distributed along the x axis from the origin to the point x = 10 centimeter. Find what is the electric potential
Block B in the figure weighs 740 N. The coefficient of static friction between block and table is 0.24; angle ? is 31°; Find the maximum weight of block A
The flash unit in a camera uses a 9 V battery to charge a capacitor.The capacitor is then discharged through a flash lamp. obtain the capacitance of the capacitor
A .1 kg meterstick is supported at its .4m mark by a stringattached to the ceiling. A .7 kg mass hangs vertically from the.05m mark. A mass is attached somewhere on the meterstick to keepit in both horizontal and rotational and translational equil..
A satellite is in a circular orbit around an unknown planet. The satellite has a speed of 1.60 104 m/s, and the radius of the orbit is 5.00 106 m. A second satellite also has a circular orbit around this same planet. The orbit of this second satellit..
Two charges, qA and qB, are divided by a distance, d, and exert a force, F, on each other. Analyze Coulomb's law and answer the following questions.

At a steam power plant, steam engines work in pairs, the heatoutput of the first one being the approximate heat input of thesecond. at what rate must coal be burned
A beam of red light, whose frequency is 4.30*10^14, passes through a piece of dense flint glass (n=2.13) in 25 ps (picoseconds). Find the thickness of the glass
Two mirrors form a vertex with an angle of 128°. If a ray of light strikes mirror 1 with an angle of incidence of 48°, find the angle of reflection of the ray when it leaves mirror 2
A loop of diameter d = 10 cm, carrying a current I = 0.2 A is placed inside a magnetic field = 0.3 T. Calculate the magnitude of the torque on the loop
One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26 , starting fro..
