Question: Using the data in Table and the fact that Ulrey's spectrometer used a calcite crystal:
a. Calculate the wavelengths corresponding to angles of reflection, and then plot the intensity of the x-radiation vs. λ
b. What is the energy of the photon that corresponds to the wavelength at which the intensity is a maximum?
c. By extrapolation of your graph determine the short-wavelength cutoff.
d. What is the voltage difference through which these electrons passed before they struck the tungsten anode of the x-ray tube?
Determine the sign, magnitude and position of a third charged object that causes all three objects to remain in equilibrium (to remain at rest). Show your work and explain your reasoning.
A car drives straight off the edge of a cliff that is 64-m high. The police at the scene of the accident note that the point of impact is 110-m from the base of the cliff. How fast was the car travelling while it went over the cliff.
Oil with index of refracton n=1.25 floats on water with index n=1.33. For normal incidence, what maximum film thickness will reflect red light of wavelength 650nm most strongly
Suppose the first stage of a two-stage rocket has total mass 1.30×10^4 kg, of which 1.10×10^4 kg is fuel. The total mass of the second stage is 1000 kg, of which 700 kg is fuel. What is the final speed of the second stage
Even though energy is conserved for the system, why is it a good idea to make the components of the drive mechanism as light as possible (with the exception of the flywheel)?
Force on a Particle A force F = (4.0 N)i + (c N)j acts on a particle as the particle goes through displacement d = (4.0 m)i - (2.0 m)j. (Other forces also act on the particle.) What is the value of c if the work done on the particle by force F is eac..
A mass rests on top of the piston. The initial temperature of the system is 305 K and the pressure of the gas is held constant at 137 kPa. The temperature is now increased until the height of the piston rises from 23.4 cm to 27.0 cm. What is the f..
In a local bar, a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.22m. The mugslides off the counter and strikes the floor 1.40m from the base ofthe counter.
A 14 liter tank of helium is at a pressure of 164 kPa at a temperature of 0 C, What is the speed of the helium atoms in the tank at this new volume, How many moles of helium are there in the tank
Four point charges are located at the corners of a square with each side of length (l) = 5.0 cm, as shown in the figure from the last problem. Charge q1 = q2 = +2.0 uC and charge q3 = q4 = +1.0 uC. Assume that a charge q5 = -2.0 uC is placed at po..
