In t-ball, players use a bat to hit a stationary ball off of a stand. In one hit, the 0.14kg ball leaves the bat at 12 m/s after being in contact with the bat for a certain period of time. If the acceleration of the ball is. 6000m/s2, what is the time that the ball is in contact with the bat? Assume constant acceleration and answer in ms.

The answer is b hope this

A. to determine if humans can explore mars safely

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
