Answer:

C. Source A is negatively charged and source B is positively charged.

Explanation:

As per the properties of electric field lines we know that electric field lines originated out from the positive charge and then terminated back into the negative charge.

As per the given presentation of field lines we can see that field originated out from charge placed at B and these field lines again terminated into the charge placed at A.

So here the charge must be positive at position of B and it is negative at position of A.

so correct answer will be

C. Source A is negatively charged and source B is positively charged.

Note that the electric field lines begin from the higher voltage to the lower

Because the negative pole is lower voltage than the positive pole

The lines go out the positive charges and go in the negative charges

Then, the correct statement is:

<u>C. Source A is negatively charged and source B is positively charged.</u>

Which of these is an example of electrical energy being converted to mechanical energy?
GalinKa [24]

Answer:

Ceiling fan

Explanation:

Ceiling fan is a perfect and typical example of electrical energy being converted to mechanical energy.

In most systems, energy is usually transformed from one form to another. Energy is not created neither is it destroyed. We know this by virtue of law of conservation of energy.

  • The ceiling fan is powered by electrical energy from an outlet.
  • The energy from the outlet is used to drive the blades of the fan and set them into motion.
  • This is mechanical energy.

A 14.0 gauge copper wire of diameter 1.628 mm carries a current of 12.0 mA . A) What is the potential difference across a 1.80 m
Serga [27]

Answer: a) 139.4 μV; b) 129.6 μV

Explanation: In order to solve this problem we have to use the Ohm law given by:

V=R*I whre R= ρ *L/A  where ρ;L and A are the resistivity, length and cross section of teh wire.

Then we have:

for cooper R=1.71 *10^-8* 1.8/(0.001628)^2= 11.61 * 10^-3Ω

and for silver R= 1.58 *10^-8* 1.8/(0.001628)^2=10.80 * 10^-3Ω

Finalle we calculate the potential difference (V) for both wires:

Vcooper=11.62* 10^-3* 12 * 10^-3=139.410^-6 V

V silver= 10.80 10^-3* 12 * 10^-3=129.6 10^-6 V
