A powerful motorcycle can accelerate from 0 to 30.0 m/s (about 108 km/h) in 4.20 s. What is the angular acceleration of its 0.320-m-radius wheels

A window washer drops a brush from a scaffold
on a tall office building.
What is the speed of the falling brush after
3.08 s? (Neglect drag forces.) The acceleration
due to gravity is 9.8 m/s^2.
Answer in units of m/s.

Calculate the Hall coefficient for potassium which has a bcc structure with a lattice
constant of 0.538 nm.

Show that the probability that an energy level which is at an energy ∆E above the
Fermi level is occupied is equal to the probability that an energy level ∆E below the
Fermi level is not occupied.

At what angle will a diffracted beam emerge from the (111) planes of a face centered
cubic crystal of unit cell length 0.5 nm? Assume diffraction occurs in the first order
and that the x-ray wavelength is 0.3 nm?
