Police brutality is an ugly term we don't want to hear. Unfortunately, it's part of the necessary and sometimes nasty business called policing. Fortunately, it rarely occurs. But when it does -- it's big news. I'm a sophomore in high school and we are in the process of writing a research paper.
Best Answer: Change of internal energy equals heat transferred to plus work done on the gas, i.e.: âU = Q + W = 300kJ - 350kJ = -50kJ. Source(s):est Answer: Change of internal energy equals heat transferred to plus work done on the gas, i.e.: âU = Q + W = 300kJ - 350kJ = -50kJ. Source(s):
Unit 26 Types of Energy Energy can neither be created nor destroyed. Energy changes from one kind to another. The total energy of an object never changes. Anything that has mass and movement has kinetic energy.The kinetic energy of an object in this case is given by the relation: KE = (1/2)mv2 m=mass of the object V=velocity of the object The greater the mass or velocity of a moving object, the more kinetic energy it has.ind power uses mechanical energy to help create electricity. Potential energy + Kinetic energy = Mechanical energy Mechanical Energy Summary Gravitational PE Elastic PE The energy of motion mgh Energy that is stretched or compressed.
