a) the sun is at the center of the solar system.
b) the sun’s mass is much greater than earth’s.
c) earth rotates about its axis, but the sun does not.
d) other planets also try to move the sun around them

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

(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?
