1.For an angle of zero between the magnetic field and the vector
normal to the plane of the coil: (a) What happens to the light bulb
as it enters the magnetic field region? Explain. (b) What happens
to the light bulb as it moves while it is completely inside the
magnetic field? Explain. (c) What happens to the light bulb as it
exits the magnetic field region? NOTE: Use Faraday’s Law to
explain.

5. Sketch two views of a turning operation to show that the back
rake angle and
the side rake angle correspond to the inclination angle and the
effective rake
angle, respectively.
A tennis ball rolls off a vertical cliff at a projection angle
of zero degrees to the horizontal (no initial vertical motion
upwards) with a horizontal velocity of 11.52 m/s. If the cliff is
-25 m high, calculate the horizontal distance in metres out from
the base of the cliff that the ball will land.
*Bragg Scattering
What is the Bragg Scattering angle (i.e. the angle, in degrees,
between the incoming incident beam and the reflected beam) for
electrons scattered from a nickel crystal if their energy is 63 eV?
The spacing between Ni Bragg planes is 0.215 nm. Give your result
to 3 significant figures.
