Physics help please:Explain the mechanism by which AC (alternating current) through the primary circuit of a transformer produce

Makovka662 [10]

<span>In the transformer we use from faraday's law.in this low when a variable current pass from a loop of wire, make variable flux and when variable flux in a loop make variable current in loop.be careful that current or flux must to be variable.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

A resistor, capacitor, and switch are all connected in series to an ideal battery of constant terminal voltage. Initially, the s

erma4kov [3.2K]

Answer:

The voltage across the resistor is zero, and the voltage across the capacitor is equal to the terminal voltage of the battery.

Explanation:

This is because when a capacitor is charged no current or voltage flows through it so it will have a voltage equal to the terminal voltage of the battery

2. A student drives 7.8-km trip to school and averages a speed of

Alekssandra [29.7K]

Answer:

<em>The total time is: t=451.22 sec</em>

<em>The average speed is: V=34.57 m/s</em>

Explanation:

<u>Average speed</u>

The average speed is calculated by dividing the total distance traveled by an object (x) by the total time it took it to travel that distance (t).

$\displaystyle V=\frac{x}{t}$
