I am an engineer building a new hair dryer. I have developed an efficient motor to move the air around, and filaments to heat the air as it passes through. However, when I test my hair dryer using different amounts of current, I find that the hair dryer overheats when current passes 13 amps. To ensure this is not dangerous for my customers, what should I install into my hair dryer? How does it work? Where would I install it?

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
