On a guitar string fixed at both ends the fundamental frequency is 100hz. If the string is 1m long what’s the speed of the waves on the string? 50m/s
400m/s
100m/s
200m/s

The answer to your is is c motion and shape

Wavelength = pie*69+69 with ur mom

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
