B) A 5 kg mass is placed next to the end of the spring when it is compressed 0.60 m and the whole thing is let go. Neglecting the mass of the spring, how much potential energy has been lost by the mass when
it passes the point where the spring is compressed at 0.40 m?

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 big glowy thing is called the sun it is a star in our galaxy and is over 1 million degrees

Ai think hope that
