The emission wavelength lies between 275 nm and 450 nm and the light yield per neutron is reported to be 20000 photons/MeV neutron energy

(a) What largest work function of a material used for a photo cathode would be acceptable that still allows detection of an emission originating from the scintillator?

(b) What is the maximum kinetic energy of electrons emitted from the photo cathode, given the emission wavelength range of the scintillator?

(c) How much charge is being generated per single neutron, assuming a 3 MeV neutron and a photon-to-electron conversion efficiency (quantum efficiency) of 15%? Would this charge be detectable if you use an Electrometer2 that has a resolution limit of 10 fC?

Ernest Rutherford (the first New Zealander to be awarded the Nobel Prize in Chemistry) demonstrated that nuclei were very small and dense by scattering helium-4 nuclei (⁴He) from gold-197 nuclei (¹⁹⁷Au). The energy of the incoming helium nucleus was 7.97 ✕ 10⁻¹³ J, and the masses of the helium and gold nuclei were 6.68 ✕ 10⁻²⁷ kg and 3.29 ✕ 10⁻²⁵ kg, respectively (note that their mass ratio is 4 to 197). (Assume that the helium nucleus travels in the +x direction before the collision.)

A)If a helium nucleus scatters to an angle of 116° during an elastic collision with a gold nucleus, calculate the helium nucleus' final speed (in m/s) and the final velocity (magnitude in m/s and direction counterclockwise from the +x-axis) of the gold nucleus. b) What is the final kinetic energy (in J) of the helium nucleus?

A heat engine made with an ideal gas with f = 5 degrees of freedom has 3 steps. Starting with a volume of 8 liters and a pressure of 1.3 × 10^5 Pa, the gas is compressed adiabatically to a volume of 1 liter and a pressure P2. Next the gas expands at constant pressure back to 8 liters, then the pressure drops at constant volume back to 1.3×10^5 Pa. Draw the cycle in a P −V diagram. Calculate the pressure P2. Calculate the efficiency of the engine. Calculate the ratio Tmin/Tmax of minimum and maximum temperatures during the cycle and compare the efficiency of this engine to eCarnot of a Carnot engine operating with the same value of Tmin/Tmax.

if a rocket was orbiting a planet and then the mass of the planet suddenly decreased what would happen to the movement of the rocket?

A computer disk drive is turned on starting from rest and has constant angular acceleration.

Part A

If it took 0.420 s for the drive to make its second complete revolution, how long did it take to make the first complete revolution?

Part B

Explain the differences between primary electrons, secondary electrons, Auger electrons, and backscattered electrons and how they are used in SEM imaging and analysis

1) projectile blitz:
a) given an initial velocity (Vx0,Vy0) off a cliff of height H, what
is the final velocity? What is the horizontal distance
traveled? How much time is the projectile in the air for?

b) given a launch angle theta for the same case of launching off a
cliff of height H, and given a horizontal distance d to a target that
the projectile is supposed to hit, what speed should the projectile be
launched at?

2) Liz May is travelling South with speed Vm.  Jagmeet Singh is travelling
west with speed Vs. At time 0, May is a distance Ym North of a
political intersection, and Singh is Xs to the east of the
intersection. Find the distance of closest approach.

3) A person of mass m is on a massless weight scale in an elevator of
mass M being pulled up by a cable with tension T. The tension is large
enough to cause positive vertical acceleration. What weight does the
scale read?

4) What banking angle for a circular race track of radius R would
be optimal for race cars going speed V?

1) A cylinder of Mass M and radius R, and initial speed V, starts
rolling up an incline of angle theta relative to horizontal. Assuming
no slipping, how high up does the cylinder get?

2) teeter/totter
a) Peewee has mass m and his big buddy Delilah has mass 2m. If Peewee
sits at one end of a uniform teeter totter of length L and mass M, how
far from the central pivot should Delilah sit (ie on the other end) to
be balanced?

b) Delilah instead chooses to sit at the far end from Peewee. What
vertical acceleration does Peewee experience when they start from a
level teeter/totter from 0 angular velocity at horizontal? Provide an
answer that is a function of the angular displacement (theta) from the
horizontal. What normal force does Peewee experience as a function of
theta?

3) A baseball-crazy astronaut in space catches a fastball. What happens?
Let's treat the astronaut as a rod of length L and mass M and assume
the ball of mass m attaches a distance L/5 from one
end. Compute/describe the resultant motion. Note the moment of inertia
for a solid rod is ML^2/12 for rotation around its center of mass. Hint,
you will have to use the parallel axis theorem for moment of inertia.

An open container holds ice of mass 0.570 kg at a temperature of -13.7 ∘C. The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 730 J/minute. The specific heat of ice to is 2100 J/kg⋅K and the heat of fusion for ice is 334×10^3 J/kg.
