Accepted Answer

A) True 
 B)False  True

Question 2

How is the observed height of Polaris above the horizon related to an observer's latitude? (Hint: Consider three cases of observers located at the equator,the North Pole,and latitude = +45$\circ$.)

Accepted Answer

The observed height of Polaris above the horizon is equal to an observer's latitude.For an observer at the equator (latitude = 0^$\circ$),Polaris is on the horizon.For an observer at the North Pole (latitude = +90^$\circ$),Polaris is at the zenith or 90° above the horizon.For an observer at latitude = +45^$\circ$,Polaris is 45° above the horizon.
