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 […]

Who can run faster Boy or girl? Males develop bones faster. Some girls run faster than boys and some boys run faster than girls. Girls may not develop bones as fast as males do because girls are mature and their growth changes at a young age. What should I eat to run faster? Power foods: […]

What is the L quantum number? The angular quantum number (l) describes the shape of the orbital. Orbitals have shapes that are best described as spherical (l = 0), polar (l = 1), or cloverleaf (l = 2). They can even take on more complex shapes as the value of the angular quantum number becomes […]

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 […]

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 […]

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 […]

Is a piece of information that is used to support a main idea? Evidence. Evidence is any piece of information used to support an idea or argument. Although evidence is not necessarily based in quantifiable fact, it is used to reinforce the idea of an argument, topic sentence, or main idea. When you look for […]

How do you know if a gas is produced in a chemical reaction? Signs of a Reaction – Gas Formation The formation of a gas is the third sign that a reaction may have occurred. The formation of bubbles when two liquids are mixed usually indicates that a gas has formed. A gas can also […]

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 […]
