PLEASE HELLPPP ILL GIVE which part of the United States would have generally cooler temperatures due to the effects of currents?

A ) East Coast
B ) Gulf Coast
C ) West coast
D ) Central States

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

The object's initial distance above the groundthe object's initial velocity

There was no intial y-momentum so the net final y-momentum must also be 0. they can have final velocities in the y-direction
