Adc current of 60 ma can cause paralysis of the body's respiratory muscles and hence interfere with breathing, but only 15 ma (rms) of ac current will do the same thing. suppose a person is working with electrical power lines on a warm humid day and therefore has a low body resistance of 1100 ohms. what dc and ac (amplitude and rms) potentials would it take to cause respiratory paralysis?

Alice added sodium chloride to water and stirred the water for several minutes. alice is most likely trying to demonstrate that ionic compounds a. are hard. b. can dissolve. c. are clear. d. can melt.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
