The voltage-current relationship for the circuit shown in Fig P1.17 is given by Ohm’s law as V=I R, where V is the current in amps, and R is the resistance of the resistor in ohms. (a) Sketch the graph of I as a function of V if the resistance is 5 ohms.
(b) Find the current I if the applied voltage is 10 V.

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

An electric current is flowing through the cord below.what will happen to this current if a magnet is brought near the cord? a. the electric current will stop flowing. b. it will exert a force on the voltage. c. the resistance of the wire will decrease. d. it will exert a force on the electric current.
