(c9p4) A wheel starts from rest and rotates about its axis with constant angular acceleration. After 8.9 s have elapsed, it has rotated through an angle of 10 radians. What is the angular acceleration of the wheel? What is the angular velocity when the time $t = 8.9$ s? What is the centripetal acceleration of a point on the wheel a distance $r = 0.40$ m from the axis at $t = 8.9$ s?

2. A \"quantum dot\" particle is going to be used in an experimental cancer medication. The particle has to be designed to absorb photons at a wavelength of 850 nm (1.46 eV) and convert them into heat through non-radiative processes (the exact mechanism is not relevant here). You can treat the quantum dot as a one-dimensional infinite quantum well and assume that the electrons have their free electron mass. The photons should excite electrons which are in the ground state (first energy level) to the second energy level. What size does the quantum dot need to be at to ensure optimal photon absorption?

Calculate the size of a solar photovoltaic farm with a daily 1 MW power, operating for an average of 10 hours daily. Use a solar panel measuring 1m x 2m with 20% overall efficiency. The solar irradiance in the farm is about 300 Wh/m2. Assume the output of this farm is used to produce hydrogen from the electrolysis of water. Calculate the volume of hydrogen (in cubic meters) that can be produced at 500 atmospheres. Assume 90% efficiency for the electrolysis cells.
