When operated on a household 110.0 V line, typical hair dryers draw about 1650 W of power. The current can be modeled as a long, straight wire in the handle. During use, the current is about 1.95 cm from the user's hand.

a. What is the current in the dryer?
b. What is the resitance of the dryer?
c. What magnetic field does the dryer produce at the users hand?

Explanation:

Given that,

Voltage of household line, V = 110 V

Power of the hairdryer, P = 1650 W

During use, the current is about 1.95 cm from the user's hand.

(a) Power is given by :

(b) Again the power is given by :

R is resistance of the dryer

(c) The magnetic field produced by the dryer at the user's hand is given by :

Hence, this is the required solution.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
