When a stretched string is clamped at both ends, its fundamental frequency is 140 hz, (a) what's the next higherfrequency? if the same string, with the same tension, is now clamped at one end and free at the other, what are (b) thefundamental and (c) the next higher frequency?

What should the power status of a circuit be when measuring resistance with an ohmmeter?

You are about to open a container of soy milk but notice that there are instructions to “shake well before serving.” the soy milk is most likely a

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?
