If the momentum of an object is tripled, its kinetic energy will change by what factor? How to find average force with momentum? How does mass and acceleration affect force? What are the units of linear momentum? What can the law of conservation of momentum predict?
To answer the question about how the average kinetic energy and average potential energy of molecules of a substance change during its phase change at a constant temperature while heating, we can break it down into two parts:3. Conclusi
If He(g) has an average kinetic energy of 4470 J/mol under certain conditions, what is the root mean square speed of N_2(g) molecules under the same conditions? Why do we use the root-mean-square speed instead of the average velocity to describe a gas that follows...
which gets calculated on the basis of average operations conditions. According to the EPA (Environmental Protection Agency), each gallon of gasoline is equivalent to 33.7 kWh of electricity. There is also growing concern about the high amounts of energy that is needed to manufacture EV or Electri...
Heat tends to "move" from warmer to cooler areas, that is, into regions into which there is presently less heat. While heat cannot be held or seen, changes in its magnitude can be measured via changes in temperature. Temperature is a measure of the average kinetic energy of a set of mo...
That's why (confusingly) you'll sometimes read in books that uranium-235 fission produces "two or three" spare neutrons (and an average of 2.47) per reaction.What's the difference between a nuclear power plant and a nuclear bomb?
Train manufacturer CSX estimates that their fleet moves 1 ton (0.9 metric tons) of cargo an average of 492 miles (791 kilometers) per 1 gallon (4 liters) of fuel, making locomotives four times as efficient as moving goods on roadways. Diesel-electric systems are also five times more ...
kinetic energy, which can be captured, just like the energy in moving water can be captured by the turbine in ahydroelectric dam. In the case of awind-electric turbine, the turbine blades are designed to capture the kinetic energy in wind. The rest is nearly identical to a hydroelectric ...
and the power of the engine is increased. Supercharging adds anaverage of 46 percentmore horsepower and31 percentmoretorque. In high-altitude situations, where engine performance deteriorates because the air has low density and pressure, a supercharger delivers higher-pressure air to the engine so...
One of the most noticeable effects of variations in Earth's gravitational field is on sea levels. Water is drawn to the spots where gravity is strongest, creating sea levels higher than average, while areas with lower gravity have lower sea levels. Gravity at the Indian Ocean geoid low is ...
