Thickness of the filmThe UC Davis physicist measures the thickness of a layer of a benzene with nb= 1.50 by shiningmonochromatic light onto the film and varying the wavelength of the light (the film is in the air with n= 1). She finds that the light of wavelength 635 nm is reflected most strongly from the film.

(a) What is the minimum thickness of the film?
(b) What would be the wavelength of the most reflected visible light if the same layer was placed onthe surface of water withnw= 1.3 while the laser still shines from the air.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
