Problem Q18.4

The coolant in an automobile radiator is kept at a pressure higher than atmospheric pressure. Why is this desirable? The radiator cap will release coolant when the gauge pressure of the coolant reaches a certain value, typically 15 lb>in.2 or so. Why not just seal the system completely?

Problem 29.47 An asteroid with a mass of 8.4×1011 is observed to have a relativistic momentum of magnitude 7.76×1020 . Part A What is the speed of the asteroid relative to the observer ANSWER: = 2.85×108 Correct Relativistic Energy and Momentum Conceptual Question A muon is traveling at relative to a laboratory frame of reference. The speed of the muon is doubled to . Part A What happens to the momentum of the muon in the laboratory frame of reference Hint 1. Relativistic momentum The momentum of a particle can be related to its rest massand its speed by . The term in the denominator is so common in relativity that this equation is often written , where is called the relativistic factor and is defined as
