Protons in cosmic rays have been observed with kinetic energies as large as 1.0×1020eV. How fast are these protons moving? Give your answer as a fraction of the speed of light. - the answer is not 4.6*10^5c I've already tried that. Show that the kinetic energy of a single one of these protons is much greater than the kinetic energy of a 15 mg ant walking with a speed of 8.8 mm/s.
1.) N2 and Kr are sealed in two separate identical jars at STP. Compare the average kinetic energies and average molecular velocities of these gases. 2.) When a metal rod, mass 21.9 g, heated to 85 C is placed into a coffee-cup calorimeter containing 200.0 ml of water at 20.0 C, the equilibrium temperature achieved by the system is 21.5 C. What is the heat capacity of metal?

just looking for the answers Question 5. If two particles have equal Kinetic energies, are their momenta equals? (K = my? 12. p = my ). a) Yes, always b) No, never c) Yes, as long as their masses are equal d) Yes, if both their masses and directions of motion are the same e) Yes, as long as they move along parallel lines Question 6. Which force is responsible for holding a car in an unbanked curve level road)?...
Compare the kinetic energies of two objects, A and B, identical in every respect except one. Assume that the single difference is: Object A has twice the velocity of B. Object A moves north, B south. Object A moves in a circle, B in a straight line. Object A is a projectile falling vertically downward; B is a projectile moving vertically upward at the same speed. Object A consists of two separate pieces attached by a light string, each equal in...
a) How do the pressures at points A and B compare? b) How do the velocities of the fluid at points A and B compare? c)How do the flow rates at points A and B compare? I've been having trouble with this homework assignment and am unsure how to explain. In the figure below, air is flowing incompressibly through the horizontal pipe.
5) An electron gun sends out a beam of electrons whose kinetic energies are all about 53 μμeV. (1 μeV=1.6×10−25 J1 μeV=1.6×10−25 J.) You need to set up a magnetic field perpendicular to the beam that causes it to turn through a 90∘∘ circular arc of length 3 mm. How strong must the magnetic field be? [Note: electrons have a mass of about 9.11×10-31 kg.] 5) An electron gun sends out a beam of electrons whose kinetic energies are all...
