2. A point source of 60Co gamma rays emits equal numbers of monoenergetic photons of 1.17 MeV and 1.33 MeV, giving a flux density of 5.7 x 109 photons cm-2 sec-1 at a specified location. What is the energy flux density there, expressed in erg cm-2 sec-1 and in J m-2 min

Distinguish between linear momentum and angular momentum

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
