Temperature Scales

The world seems to think that a new temperature scale is needed, the NurAn degree. On this scale it is decided that water will freeze at 17 degrees NurAn and boil at 167 degrees NurAn. On this scale, what is the body's average core temperature? How about absolute zero? One day a nurse's temperature is measured as 75 degrees NurA ...continues

Anesthetic vaporization and controlled delivery

In a vaporizer a volatile anesthetic liquid is evaporated into a gas which eventually flows to the patient. A lot of attention is directed toward temperature maintenance in order to assure that the patient receives the proper concentration. Why is temperature control important? What methods can be used to actually control the ...continues

Doppler problem

What is the doppler effect? Assume that a sound source is moving toward a sound detector at a speed of 60 m/s. According to the stationary detector, by what fraction does the frequency of the sound shift? Assume the speed of sound to be 330 m/s. Will the frequency appear to be higher or lower? Assume now police operated microwav ...continues

Flowmeter problem

A flowmeter (not doppler) is the topic. Upon what basic principle does it operate? Would such a device work for an ion free fluid?

Description of motion of a test particle in the non-null electromagnetic field.

General Theory of Relativity. Description of motion of a test particle in the non-null electromagnetic field.

Semiconductor Light Detectors

A p-n photodiode acts as a photocell, the circuit is shown in this document. Outline the band profile of the diode for infinitely large RL for different levels of illumination.

Power

A.) A car with a mass of 1.50 x 10^3kg starts from rest and accelerates to a speed of 18.0 m/s in 12.0s. Assume that the force of resistance remains constant at 400.0 N during this time. What is the average power developed by the car's engine? B.) How long does it take a 19kW steam engine to do 6.8 x 10^7 J of work? C.) ...continues

Power output and work

A 50.0 kg student climbs 5.00 m up a rope at a constant speed. If the student's power output is 200.0 W, how long does it take the student to climb the rope? How much work does the student do? Please answer the question, show the formula used and the work. Thank you!

Rotational equilibrium

I am trying to help my brother (in high school) understand how to solve rotational equilibrium problems. What he needs is a explanation on how to approach these problems. I understand each problem is different, but I imagine there must be a general method for solving them. I have put a problem below so that hopefully you could a ...continues
