In an ac machine, the relative angular position of the rotor’s MMF against the stators’ MMF increases from 30° to 60°. Assume that the magnitude of the MMF’s have no change. How should the electromagnetic torque change? Explain

a. Torque will be doubled.

b. T2= ?3 T1 where 2 notates after position change and 1 notates the original torque.

c. No change since there is no magnitude change in MMF.

Week 2 HW: Elasticity Step 1 - E L A S T I C or INELASTIC? Price Elasticity of Demand is a measure of how responsive demand is to a change in price. If a price change leads to a considerably bigger change in quantity demanded, we would consider the good to be responsive to a price change—hence elastic. If, however, a similar price change leads to a much smaller change in demand, we would consider it inelastic. To get...

Please answer all not understanding: 1. Volumetric expansion coefficients of simple materials are often well catalogued. However, the thermal expansion coefficient β of a human body is less well known. This could affect the human body\'s specific gravity and, therefore, measurements of its body/fat ratio. Suppose that a human body of weight w0 (on dry land) is placed on a scale while completely immersed in formaldehyde of temperature T1. Once the temperature increases by ΔT, the scale reading drops by...

original question was Consumers and public interest groups are scrutinizing—and sometimes criticizing—the privacy policies of firms and raising concerns about potential theft of online credit card information or other potentially sensitive or confidential financial information. Others maintain online privacy fears are unfounded and that security issues are as much a concern offline. They argue that the opportunity to steal information exists virtually everywhere, and it’s up to consumers to protect their interests. What do you think? * devil's advocate: One...
