While surveying a cave, a spelunker follows a passage 190m straight west, then 210m in a direction 45.0east of south, and then 270m at 30.0 east of north. after a fourth unmeasured displacement, she finds herself back where she started. i need to use vector components to find the magnitude and direction of the fourth displacement.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
