An asteroid is a celestial body. A large number of asteroids form a doughnut-shaped ring in space called the main asteroid belt. Which planets’ orbits is the belt located between?

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

Work is reduced while time is decreased

The correct answer is  ait's a process by which rocks and minerals undergo in their composition^o^
