Agamma-ray photon changes into a proton-antiproton pair. ignoring momentum conservation, what must have been thewavelength of the photon (a) if the pair is stationary after creation, and (b) if each moves off at 0.6c. perpendicular to themotion of the photon? (c) assume that these interactions occur as the photon encounters a lead plate and that a leadnucleus participates in momentum conservation. in each case, what fraction of the photon’s energy must be absorbed bya lead nucleus?

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
