A space ship is traveling above the Earth at 250 m/s when it must decelerate to enter the Earth's atmosphere. a. If its acceleration is -35 , how long it will take to stop before hitting the Earth's atmosphere? 7.14
S
b. How far it will travel in this time?
m
c. The velocity of the spacecraft after 3 seconds.
v m/s
m

The answer is orbit around nucleus

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
