Does energy have momentum? Light indeed carries energy via its momentum despite having no mass. Public Domain Image, source: Christopher S. Baird. In the above equation, E is the total energy of the particle, p is the momentum of the particle (which is related to its motion), c is the speed of light, and m […]
How many PSI is a brake line?
How many PSI is a brake line? Metal brake lines must withstand 5000 psi tests, and most burst around 15,000 psi. Typical full-lock operating pressures on conventional OEM-style automotive hydraulic-brake systems are 900–1,000 psi (69 bar) with manual brakes and 1,400-plus psi (96 bar)with power-assisted brakes. Is it illegal to use compression fittings on brake […]
Are combustion engines more efficient?
Are combustion engines more efficient? How efficient are engines? Combustion engines are stupefyingly inefficient. Most diesel engines do not even have a thermal efficiency of 50%. Of every gallon of diesel burned by a combustion engine, less than half of the energy generated becomes mechanical energy. How long will internal combustion engines be around? The […]
What are the main factors that affect density altitude?
What are the main factors that affect density altitude? There are three important factors that contribute to high density altitude: Altitude. The higher the altitude, the less dense the air. Temperature. The warmer the air, the less dense it is. Humidity. 80 oF. 90 oF. 100 oF. 110 oF. 120 oF. How does the temperature […]
What is the L quantum number?
Why do they say feels like temperature?
Why do they say feels like temperature? The “feels like” temperature is a measurement of how hot or cold it really feels like outside. For example, skin that is exposed to wind and cold temperatures will make a person feel that it is colder outside than it really is because heat is drawn away from […]
Which best explains why water is able to stick to the side of glass?
Which best explains why water is able to stick to the side of glass? Which best explains why water is able to “stick” to the side of glass? Strong adhesive forces exist between glass and the water molecules. Which statement best describes a true solution? A solution is said to be a true solution if […]
How do you know if a gas is produced in a chemical reaction?
What is range of normal distribution?
What is range of normal distribution? The area under each curve is one but the scaling of the X axis is different. Note, however, that the areas to the left of the dashed line are the same. The BMI distribution ranges from 11 to 47, while the standardized normal distribution, Z, ranges from -3 to […]
