To solve this problem we will use the concepts related to Ohm's law for which voltage, intensity and resistance are related.

Mathematically this relationship is given as

V = IR \rightarrow R= \frac{V}{I}

Where,

V= Voltage

I = Current

R = Resistance

The value of the given voltage is 12V, while the current is 12mA, therefore the resistance would be

R = \frac{12}{12*10^{-3}}

R = 1000 \Omega

Therefore the resistance is 1000\Omega

vlabodo [156]

Answer:

mu=12Tm^2

Explanation:

the magnetic moment mu of a single loop is given by:

\mu = I A B

where I is the current, B is the magnetic field and A is the area of the loop. By replacing we obtain:

\mu=(0.5A)(4m*2m)(3T)=12Tm^2

hope this helps!!

The current in a hair dryer measures 19 amps. The resistance of the hair dryer is 14 ohms. What is the voltage?
Masja [62]
Voltage  =  (current) x (resistance)

             =  (19 A)  x  (14 ohms)  =  266 volts .

Note:  Be careful using that thing ! 

It's dissipating

       I² R  =  (19 A)² x (14 ohms)  =  5,054 watts ! ! !

That's an awful lot of power for a blow-dryer ! 

The dryer is certainly not using very much of that power to run the fan. 
Most of it is being used to heat air.  5 kilowatts is more power than most
toasters or microwave ovens use, so please be careful with how much of
your hair or skin you expose to that hot-air blast.  You could probably cook
a meatloaf with it.

A(n) 0.49 kg softball is pitched at a speed of 13 m/s. The batter hits it back directly at the pitcher at a speed of 23 m/s. The

<h2>Impulse  = 4.9 kgm/s</h2>

Explanation:

Impulse is given by change of momentum.

Mass of softball = 0.49 kg

Initial velocity of softball = 13 m/s

Initial momentum = 0.49 x 13 = 6.37 kgm/s

Final velocity of softball = 23 m/s

Final momentum = 0.49 x 23 = 11.27 kgm/s

Change of momentum = Final momentum - Initial momentum

Change of momentum = 11.27 - 6.37

Change of momentum = 4.9 kgm/s

Impulse = Change of momentum

Impulse  = 4.9 kgm/s
