A 150-Ω resistor is connected in series with a 0.250-H inductor and an ac source. The voltage across the resistor is vR=(3.80 V)cos[(720rad/s)t]. a) Derive an expression for the circuit current.
b) Determine the inductive reactance of the inductor.
c) Derive an expression for the voltage vL across the inductor.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

i think the answer is tomato juice? not entirely sure though
