After landing on an unexplored Klingon planet, Spock tests for the direction of the magnetic field by firing a beam of electrons in various directions and by recording the following observations:

- Electrons moving upward feel a magnetic force in the northwest direction.

- Electrons moving horizontally toward the north are pushed downward.

- Electrons moving horizontally toward the southeast are pushed upward.

Mr. Spock therefore concludes that the magnetic field at this landing site is in which direction?

A) toward the east

B) toward the northeast

C) toward the southwest

D) toward the southeast

E) toward the west

The wording of this question is so confusing I can not visualize or diagram it even after reviewing the chapter and looking at various web sites on magnetic fields. Upward, downward, horizontally combined with compass directions have left me scratching my head and at a stand still. Please explain if possible. I can't appply what I know simply because I can't understand (visualize) the description of the observations.

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
