Impedance is basically the overall resistance/impeding factor against a current in an electrical circuit. Inductive and capacitive reactances are used in a formula to DETERMINE impedance (it uses resistance too) and they are basically the opposition towards a current caused by the inductor (ex. coil) and a capacitor, respectively, in an LC or RLC circuit.
Area of the bottom = L x W = 3 x 1 = 3 square meters. Pressure = force/area = 12000/3 = 4000 N/square meter = 4 kPa. Since we know the weight of the oil, we don't need to know the depth.
Because plastic and rubber are known as insulators which keep metal wires protected
Answer:
d. the force is reduced by one quarter to 3.6 n
Explanation:
I believe that the correct answer you are looking for is the distance traveled
