1. Identify the electrical properties of materials that are highly conductive and those that are used in insulation 2. Given a 10 V power supply, would a 20 ohm resistor and a 5 ohm resistor need to be arranged in parallel or in series to generate a current of 2.5 A
I also need 12 and 14

im sorry i dont know

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.
