Answer:

None of the them has a complete answer .

Explanation:

The current in a wire is a function of the conduction element geometry inside the cable, given by the resistance and the conduction area. So saying twisted/shield, is not giving us any information about the current rating of the wire.

Repairs to the wire may affect the area of the conductor, reducing the effective surface of conduction. But a well-executed repairing must made an insignificant change in the resistance. So it's not a definitive concept.

A twisted/shield wire is generally used for signal transport, as it's configured to reduce the noise in the data transmission.

Which of the following is a characteristic of electromagnetic waves?
sergiy2304 [10]
I’ll refer to electromagnetic radiation as EMR.

Visible light is a very small subset of EMR. Many other ranges like infrared, ultraviolet, or gamma must be detected by special equipment.


EMR is what makes up light, and as we know from any high school physics class, light exhibits both particle-like properties (photoelectric effect and Compton scattering) and wave-like properties (refraction, diffraction, double-slit & single-slit experiment).

EMR can travel without a medium, like the vast emptiness of space. It can also travel with a medium. It can transmit through various materials albeit at a slower speed, like water, earth’s atmosphere, glass etc.

The propagation speed of EMR in space is 3x10^8 m/s, which is a speed unattainable by any of our current means of transportation. I would say that’s quite fast.

The capacity of a storage battery, such as those used in automobile electrical systems, is rated in ampere-hours (A?h). A 50 A?h
V125BC [204]

Answer: (A) 780J

(B) 1.89×10^-11L

(C)1.67×10^-4 h

Explanation:

Energy of the battery = IVt

=13×60 = 780J

Heat combustion of

1g of gasoline relax 46000J

Therefore 780J will release 780/46000

= 0.017g

Density = mass/volume

Volume = mass/density

Volume =0.017× 10^-3 / 900

= 1.89× 10^-8 m3

= 1.89×10^-11 litres

P=IVt

t=P/IV

= 450/60×13

1.67×10^-4 hours
