1- A 3 Ω and a 6 Ω resistor are connected in series with a 12 V battery. What is the potential difference across the 3 Ω resistor? 2. A 3 Ω and a 6 Ω resistor are connected in series with a battery. A current of 1 A passes through the 3 Ω resistor. Determine the potential difference of the battery.

3. A 4 Ω resistor is placed in series with another resistor and a 12 V battery. The potential difference across the 4 Ω resistor is 8 V. Determine the resistance of the other resistor.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
