A standard cell has an emf "E" of 1.2 volts. If the resistance "R" of the circuit is increasing at the rate of 0.03 ohm/sec, at what rate is the current "I" changing 34 at the instant when the resistance is 6 ohms? Assume Ohm's law E = IR 0.003 amp/sec 0.004 amp/sec O -0.001 amp/sec -0.002 amp/sec Find the slope of the line tangent to the curve at x = 3* 35 y = x - 2x + 1 36 25 O 42 5 Evaluate: "(플) EX lim (2 – x) tan 2 36 X-1 Option 2 Option 1
