When a bullet leaves a rifle it has a lot of kinetic energy, most of which gets lost as heat. Imagine that a 9.8kg lead bullet is fired into a ort upon which the actual target was sitting . The bullets initial speed is 760 m/s, and as it comes to rest half of its kinetic energy goes into heating the bullet. How much does the bullets temperature increase
Two uniform rods of identical mass and identical length are rotating with identical rotational kinetic energy. The first rod is rotating about and axis that passes through its left end and points perpendicular to the rod. The second rod is rotating about an axis that passes through its center and points perpendicular to the rod. Which rod has a larger magnitude of angular velocity? a. They both have the same magnitude of angular velocity. b. The second rod. c. The...
Which of the following statements are true? [Select all that apply.] The average kinetic energy of a gas increases as temperature increases. The average kinetic energy of a gas depends on the masses of the gas molecules. The average kinetic energy of a gas depends on the temperature of the gas. The average kinetic energy of a gas depends on the identity of the gas. A sample of carbon dioxide and a sample of hellum would have the same average...
If a bullet has 44% more kinetic energy than an identical first bullet, then how much faster is the second bullet's speed?
This question has multiple parts. Work all the parts to get the most points. The energy of a photon needed to cause ejection of an electron from a photoemissive metal is expressed as the sum of the binding energy of the electron plus the kinetic energy of the emitted electron. When photons of 4.40x107m light strike a calcium metal surface, electrons are ejected with a kinetic energy of 1.75x10-20 J. a Calculate the binding energy of the calcium electrons. b...
Suppose you had 10 identical molecules enclosed by a box. At a given instant, one molecule has an energy of 100 Joules, and the others are all stationary.(A) What is the average kinetic energy of the 10 molecules?(B) Is this a situation of high or low entropy?(C) What happens to the energy and entropy of the molecules in the box as time passes? Does your answer depend on the insulation of the box?
