The diameter of 0-gauge copper wire is 8.252 mm. find the resistance of a 1.00-km length of such wire used for power transmission, taking into account the thermal expansion of the tungsten filament. you may assume a thermal expansion coefficient of 12×10−6/ºc. by what percentage does your answer differ from the one you get without taking the thermal expansion into account?

when it gains or loses electrons

volts times amps 6 x 0.5 3w

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.

the answer to this is proletariats.

hope this : )
