1. If an atom has an electron in the n = 8 state with ml = 3, what are the possible values of l? (Enter your answers as a comma-separated list.)
2. An object is moving along a straight line, and the uncertainty in its position is 3.00 m.
(a) Find the minimum uncertainty in the momentum of the object. Find the minimum uncertainty in the object's velocity, assuming that the object is
(b) a golf ball (mass = 0.0450 kg) and
(c) an electron.
3. The atomic planes in a crystal are spaced d = 0.41 nm apart. These planes are used in a diffraction experiment with X-rays with λ = 0.06 nm. Assume the bright fringes in the diffraction pattern are at the same angles as for a grating with slits with the same value of d. What are the diffraction angles for the first three bright fringes?
4. At the floor of a room, the intensity of light from bright overhead lights is 8.25 W/m2. Find the radiation pressure on a totally absorbing section of the floor.
5. A disk of radius R carries a total charge q uniformly distributed over its surface. The disc rotates with a uniform angular velocity about the z-axis (Taken as the axis of rotation).
(a) Calculate the magnetic field at some arbitrary point on the z-axis.
(b) What is the B-field at the center of the disk? please answers in clear writing and font
6.What is the K constant of a system of two springs hung linearly relative to k1 and k2. Derive the equation for the Ktotal of two springs hung linearly and we know k1 and k2.The equation is k = (k1*k2)/(k1+k2)
7. A converging lens of focal length 25cm produces a virtual enlarged image magnified three times that of an object. Calculate the position if the object from the lens.
