When operated on a household 110.0 V line, typical hair dryers draw about 1450 W of power. The current can be modeled as a long, straight wire in the handle. During use, the current is about 2.15 cm from the user's hand. What is the current in the hair dryer

0.075A

Explanation:

We can consider this system as a circuit, hence we can take the current from the formula for the electric power as follow

I hope this is useful for you

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.

there are no contact forces mentioned on the list of choices that you've provided.
