Which is true regarding AC current? The electrons move back and forth. The +/- polarity is constant. It is common in portable de

andre [41]

Answer: Option (a) is the correct answer.

Explanation:

AC current stands for alternating current. In an alternating current there is periodically reverse movement of current.

This means electrons move in one direction for a certain time and then they reverse their movement for the same time period and it continues in the back and forth position.

Thus, we can conclude that the statement electrons move back and forth is true regarding AC current.

A pendulum has a 0.35\ \text{kg}0.35 kg0, point, 35, space, start text, k, g, end text mass oscillating at a small angle from a

expeople1 [14]

Answer:

The frequency of oscillation of the simple pendulum is 0.49 Hz.

Explanation:

Given that,

Mass of the simple pendulum, m = 0.35 kg

Length of the string to which it is attached, l = 1 m

We need to find the frequency of oscillation. The frequency of oscillation of the simple pendulum is given by :

$f=\dfrac{1}{2\pi}\sqrt{\dfrac{g}{l}} \\\\f=\dfrac{1}{2\pi}\sqrt{\dfrac{9.8}{1}} \\\\f=0.49\ Hz$

So, the frequency of oscillation of the simple pendulum is 0.49 Hz. Hence, this is the required solution.
