Even though each item on the distance ladder is only effective within a certain distance range,
the concept is still effective because
A) distances are ultimately relative, and not absolute.
B)each technique produces exact distances on its own.
C)each step can be calibrated through its overlap with the previous step.
D)the distance ladder concept can be verified by looking in different wavelength ranges,
E)the time delay due to light travel time is significant enough to limit the accuracy of distance measurements anyway.

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.

Contrast the force of gravity between these pairs of objects: 1-kg mass and a 2-kg mass that are 1 m apart; a 1-kg mass and a 2-kg mass that are 2 m apart; and two 2=kg masses that are 1 m apart. i dont understand.
