Answer:

The magnetic flux through the conductor is   0.125\, T.m^{2}

Explanation:

Given

Perimeter of square = 2.0 m

Magnetic field strength , B = 1.0 T at 30 degree with the horizontal

Therefore angle of magnetic field with the normal , \Theta =(90-30)^{\circ}=60^{\circ}

Let side of square be a

\therefore 4a= 2.0\, m=>a=0.5\, m

Therefore area of square is given by

A=a^{2}=0.5^{2}\, m^{2}=0.25\, m^{2}

Magnetic flux through the conductor is given by

\phi =BA\cos \Theta =1.0\times 0.25\times \cos (60^{\circ})\, T.m^{2}

=>\phi =0.125\, T.m^{2}

Thus the magnetic flux through the conductor is 0.125\, T.m^{2}

20. A car battery with a 12-V emf and an internal resistance of 0.050 Ω is being charged with a current of 60 A. Note that in th
topjm [15]

Answer:

Part a)

V = 15 Volts

Part b)

P = 180 Watt

Part c)

Rate = 720 Watt

Explanation:

Part a)

When battery is in charging then the potential difference of the terminals of cell is given by

\Delta V = EMF + iR

here we know that

EMF = 12 volts

i = 60 A

r = 0.050 ohm

now we have

\Delta V = 12 + (0.050)(60) = 15 Volts

Part b)

Rate of thermal energy dissipated is the energy which is dissipating across the resistor

so here we have

P = i^2 R

P = (60^2)(0.05)

P = 180 Watt

Part c)

Rate at which Energy stored inside the cell is the rate of electrical energy that is converted into the chemical energy

Rate = EMF \times i

Rate = (12)(60)

Rate = 720 Watt

See the diagram above. Which of the following is the best prediction of what would happen if you increased the distance in secti
Inessa [10]

By the definition of wavelength, the answer is the letter D, the wavelength would decrease.

We can see in the diagram a wave motion.

A wave has some characteristics:

  • Has an amplitude, the distance from 0 to the crest (highest point in the y-direction, point (3) in the figure) it would see in the figure as (2)
  • Has wavelength, the distance between the crests.
  • Has a trough, the lowest point in the y-direction.

Now, if we increase the distance of the crests, by the definition shown above, we will increase the wavelength.

Therefore, the answer is letter D, the wavelength would increase.

A "590-W" electric heater is designed to operate from 120-V lines.
lukranit [14]

Answer:

a) 24.4 Ω

b) 4.92 A

c) 495.9 W

d)

c. It will be larger. The resistance will be smaller so the current drawn will increase, increasing the power.

Explanation:

b)

The formula for power is:

P = IV

where,

P = Power of heater = 590 W

V = Voltage it takes = 120 V

I = Current Drawn = ?

Therefore,

590 W = (I)(120 V)

I = 590 W/120 V

<u>I = 4.92 A</u>

<u></u>

a)

From Ohm's Law:

V = IR

R = V/I

Therefore,

R = 120 V/4.92 A

<u>R = 24.4 Ω</u>

<u></u>

c)

For constant resistance and 110 V the power becomes:

P = V²/R

Therefore,

P = (110 V)²/24.4 Ω

<u>P = 495.9 W</u>

<u></u>

d)

If the resistance decreases, it will increase the current according to Ohm's Law. As a result of increase in current the power shall increase according to formula (P = VI). Therefore, correct option is:

<u>c. It will be larger. The resistance will be smaller so the current drawn will increase, increasing the power.</u>
