How does the ratio of the battery (ΔVB / IB) compare to the resistance values of the resistor? Attempt to write an equation relating the (ΔVB / IB) ratio to R1, R2, and R3. (R1, R2, & R3 = resistors/lightbulbs)
(Ratio of the battery is 9:9)
(It's basically asking to write an equation relating the batteries resistance which is Voltage/I (current) to the resistors)

The slope of a velocity time graph over any interval of time gives the during that interval

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
