Question: In an electrical circuit with variable resistance, the relation V2 R depends on time, t. Pis the power dissipated by the resistor (in W),

In an electrical circuit with variable resistance, the relation V2 R depends on time, t. Pis the power dissipated by the resistor (in W), V is the voltage (in V) and Ris the resistance (in Q). Suppose that the resistance is increasing at a rate of 0.17 Q/s while the voltage is holding steady at 9 V. At what rate is the power decreasing when the resistance is 3.5 Q? 0.000 W/s Round to three decimal places if necessary
