Aprojectile thrown from the ground reached a horizontal displacement of 50 [m] and a maximum height of 100 [m]. what are the magnitude of the initial velocity v0 and the launching angle θ (withrespect to the horizontal) of the projectile? use g = 9.81 m/s^2

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

A,d, and e on edgunuity
