A transformer has an output coil with 6 times as many turns as the input coil. If the input frequency is f then the output frequ
sveticcg [70]

Answer:

d. f

Explanation:

Based on the principle of operation of transformer, when a.c voltage is applied at the terminal of the primary coil (input coil), an alternating magnetic flux is produced in the iron core which links the secondary coil (output coil).

Also, an alternating e.m.f of <em>the same frequency</em> as that of primary coil (input coil) <u>will be induced in the secondary coil (output coil) by mutual inductance.</u>

Thus, If the input frequency is "f" then the output frequency will be "f" (since the frequency will be the same).

The correct option is "D"

Two hockey pucks, labeled A and B, are initially at rest on a smooth ice surface and are separated by a distance of 18.0 m . Sim
MaRussiya [10]

Answer:8.45 m

Explanation:

Given

Two pucks are separated by a distance of 18 m

Puck A is given a push such that its velocity is 3.10 m/s

Puck B velocity is 3.50 m/s

Let they meet after time t such that Puck has traveled x m and Puck B 18-x

For same time

\frac{x}{3.10}=\frac{18-x}{3.50}

6.6x=18\times 3.1

x=8.45 m

18-x=9.55 m

So Puck has traveled a distance of 8.45 m
