The period of the sound waves produced by the motor is 8.3 milliseconds. Calculate the frequency of the sound waves please help hahhah​

Golf is for old men who smell

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

Ithink it’s: light bounce if off a mirror

Ibelieve the answer is d. macula  hope my answer has you : )
