Kinetic energies - Study guides, Class notes & Summaries

The Design: 10 m The design has 2 peaks P1 and P2 and 2 valleys V1 and V2. The launching point is A. At A, P1, and P2, the potential energy is extremely high, and the kinetic energy is extremely low. At the valleys, V1 and V2 the kinetic energies are extremely high, and the potential energies are low. Let the mass of the cart be 500 kg (represented as m). Energies and Momenta at the peaks and valleys: The po...

Absolute Temperature A temperature value relative to absolute zero. Absolute Zero The lowest possible temperature of a system, where no heat remains and the particles in the system have no kinetic energy. Avogadro Constant The number of particles that make up one mole of any gas. Boltzmann Constant A constant relating the average kinetic energy of the particles in a gas, to the gas’ temperature. Boyle’s Law The pressure of an ideal gas is inversely proportional to its volume when ...

Consider the question: Is there an attractive force between a pencil and the earth? Is this a scientific question? [Yes or No] Because III. It can be tested and answered through observations and experiments IV. The answer is already known and we find it online V. There is no way to design an experiment to answer this question. - Answer-Yes because it can be tested and answered though observations and experiments Which of the following properties ascribed to atoms by the Greeks do we still...

work a force acting upon an object to cause a displacement (movement) OR the transfer of energy that causes an object to move Work/energy is measured in _____________. joules (J) power the rate at which work is done (how long it takes to do a certain amount of work) Power is measured in _____________. watts (W) power= Work/time work= force x distance energy the capacity (ability) to do work potential energy the energy that an object has be...

X-rays: Typical diagnostic wavelength and photon energy range. - Answer-100ev-200 keV min. wavelength 6pm-12nm Structure and function of the x-ray tube. - Answer-A vacuum tube with an anode and a cathode. The cathode is heated and electrons are emitted, they are accelerated by a voltage difference in the tube. When the "brake" against the material of the anode, they release their high kinetic energy in the form of an x-ray. *x-ray tubes are of very low efficiency, most of the radiation i...

This type of surface is a good absorber and emitter of thermal radiation - correct answer Dark, rough (matt) surface This type of surface is a bad absorber and emitter of thermal radiation - correct answer Light, shiny surface In this process particles vibrate colliding with each other passing energy along. Solids are best at it, then liquids, then gases. - correct answer ...

Physics 1603 Exam Chapter 5-7 exam Review questions and answers 2024 You and your friend, who weighs the same as you, want to go to the top of the Eiffel Tower. Your friend takes the elevator straight up. You decide to walk up the spiral stairway, taking longer to do so. Compare the gravitational potential energy of you and your friend, after you both reach the top. - ANSWER Both of you have the same amount of gravitational potential energy at the top.
