Compute the voltage drop along a 26-m length of household no. 14 copper wire (used in 15-a circuits). the wire has diameter 1.628 mm and carries a 13-a current. the resistivity of copper is 1.68×10−8ω⋅m. express your answer to two significant figures and include the appropriate units

V= 2.7 [v]

Explanation:

The value of the resistance is given by:

so:

We can calulate the voltage dropped using the Ohm's law:

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.
