When operated on a household 110.0-v line, typical hair dryers draw about 1650 w of power. we can model the current as a long straight wire in the handlé. during use, the current is about 1.85 cm from the user's hand. what is the current in the dryer? number what is the resistance of the dryer? number what magnetic field does the dryer produce at the user's hand?

Current = 15 A

Resistance = 7.33 ohm

Magnetic field = 1.62 x 10^-4 Tesla

Explanation:

V = 110 V, P = 1650 W, r = 1.85 cm,

(a) Let i be the current

P = V x i

i = 1650 / 110 = 15 A

(b) Let R be the resistance

V = i R

R = 110 / 15 = 7.33 Ohm

(c) Let B be the magnetic field

B = μ0 / 4π x 2i / r

B = 10^-7 x 2 x 15 / 0.0185 = 1.62 x 10^-4 Tesla

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
