How many watts does a microwave run on

What is the magnitude of the maximum stress that exists at the tip of an internal crack having a radius of curvature of 3.5 * 10-4 mm (1.378 * 10-5 in.) and a crack length of 5.5 * 10-2 mm (2.165 * 10-3 in.

Describe the steps involved in accomplishing a life-cycle cost analysis (LCCA). I have listed the steps. just describe. a) - Operational Performance. b) - Salvage externalities c) - Value vs.

One cycle of the power dissipated by a resistor (R=800 Ω) is given by P (t) = 0.03125 W, 0≤t<12.0 sP (t) = 0.03125 W, 0≤t<12.0 s P (t) = 0 W, 12.0≤t<30 sP (t) = 0 W, 12.0≤t<30 s This periodic signal repeats in both directions of time.

A composite wall is to be used to insulate a freezer chamber at - 350C. Two insulating materials are to be used with conductivities of 0.04 W/mK and 0.1 W/mK. If the outside surface temperature of the inner layer (0.

Under EPA's regulations, which of the following methods can be used to pressurize an R11 or R123 system for the purpose of opening the system for a non-major repair? A. Adding nitrogen B. Warming the refrigerant C. Adding compressed air D.

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.

hypothetical A-B alloy of composition 40 wt% B-60 wt% A at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively.

10. Which of these requires a wheel alignment after replacement? A. Struts B. Shocks C. Both

What is the definition of diameter pitch?
