Why do most aircraft use 400 Hz AC instead of 60hz AC? 2 Answers. Induction motors turn at a speed proportional to frequency, so a high frequency power supply allows more power to be obtained for the same motor volume and mass. Transformers and motors for 400 Hz are much smaller and lighter than at […]
Can a bad battery cause electric power steering problems?
Can a bad battery cause electric power steering problems? The power steering is an electrical system, so a problem with the battery could affect the power assistance. You should still be able to steer the car even without power assistance. What happens when the EPS light comes on? It can sometimes be caused by a […]
What is it called when water sits above the glass?
Who disproved the uncertainty principle?
Who disproved the uncertainty principle? Heisenberg What happens to uncertainty when you divide by 2? You would also divide the uncertainty (or error) by 2. If you make the measurement smaller, you also make the associated uncertainty with that measurement smaller, in this case x2 smaller. Squaring the r value will result in the uncertainty […]

Which is the largest zone? Pelagic zone What are the 3 zones of ocean? There are three main ocean zones based on distance from shore. They are the intertidal […]
Why do longer chain alkanes have higher boiling points?
Why do longer chain alkanes have higher boiling points? The reason that longer chain molecules have higher boiling points is that longer chain molecules become wrapped around and enmeshed in each other much like the strands of spaghetti. More energy is needed to separate them than short chain molecules which have only weak forces of […]
What are four ways to increase the rate of a chemical reaction?
What are four ways to increase the rate of a chemical reaction? There are 4 methods by which you can increase the rate of a reaction: Increase the concentration of a reactant. Increase the temperature of the reactants. Increase the surface area of a reactant. Add a catalyst to the reaction. How can we speed […]

What does the liver do with unneeded glucose?
What does the liver do with unneeded glucose? The liver both stores and manufactures glucose depending upon the body’s need. The need to store or release glucose is primarily signaled by the hormones insulin and glucagon. During a meal, your liver will store sugar, or glucose, as glycogen for a later time when your body […]
