If two observers in the northern hemisphere are 500 miles apart but are at the same latitude, which of these statements will be true?
a. polaris will be seen by both observers at the same azimuth.
b. polaris' altitude will appear to be the same for both observers.
c. the observer farthest to the east will see polaris set (i. e., move down to the horizon) before the other observer.
d. polaris will be seen at the zenith by the observer farthest to the east before the other observer sees it at the zenith.

Aphysical change is a change in the size, shape,, or stafe of matter true or false

(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?
