6. a transformer draws 24 w of power from a 220 v power line, stepping the voltage down to 7.5 v. what is the equivalent resistance of the input circuit?

7.a circular loop of wire is in a spatially uniform magnetic field as shown. the magnetic field is directed into the screen and is perpendicular to the loop. what is the direction of the induced current in the loop, or is no current induced?

  6.  2017 Ω, about 2000 Ω.

  7.  no current is induced unless the field is changing

6. The relationship between power, voltage, and resistance is ...

  P = V²/R

Rearranging gives

  R = V²/P = (220 volt)²/(24 watts) ≈ 2016.667 Ω

The closest answer choice is 2000 Ω.

___

7. No current is induced in a stationary loop in a time-invariant magnetic field.

If something were changing, the direction of current induced would depend on whether the field is increasing or decreasing, and/or whether the loop is expanding or contracting.

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.
