Two straight wires are in parallel and carry electrical currents in opposite directions with the same magnitude of LaTeX: 2.02.0

koban [17]

Answer:

$2.4\times 10^{-5} N$

Explanation:

We are given that

$I_1=I_2=2.0 A$

Distance between the wires, $d=5.0 mm=5\times 10^{-3} m$

1mm= $10^{-3} m$

Length of other wire,l=0.3 m

Length of one wire is infinite.

We have to find the magnitude of force between the two wires.

We know that magnetic force

$F=\frac{2\mu_0 I_1I_2 l}{4\pi d}$

Where $\frac{\mu_0}{4\pi}=10^{-7}$

$F=\frac{2\times 10^{-7}\times 2\times 2\times 0.3}{5\times 10^{-3}}$

$F=2.4\times 10^{-5} N$

When the wires carrying equal current in opposite direction then the force between two wires repel to each other.

1. A pendulum has a period of 3 seconds. What's its frequency? 2. A pendulum has a frequency of 0.25 Hz. What's its period? 3. A

RideAnS [48]

Answer:

(1) 0.333 Hz

(2) 4 sec

(3) 2 sec, 0.5 Hz

Explanation:

(1) We have given time period of pendulum is 3 sec

So T = 3 sec

Frequency will be equal to $f=\frac{1}{T}=\frac{1}{3}=0.333Hz$

(2) Frequency of the pendulum is given f = 0.25 Hz

Time period is equal to $T=\frac{1}{f}=\frac{1}{0.25}=4sec$

(3) It is given that a pendulum makes 10 back and forth swings in 20 seconds

So time taken to complete 1 back and forth swings = $=\frac{20}{10}=2sec$

So time period T = 2 sec

Frequency will be equal to $f=\frac{1}{T}=\frac{1}{2}=0.5Hz$
