Answer:

a. sinusoidal wave

Explanation:

As we know that the medium particle will move in SHM when disturbance travel through the medium

Here the wave propagation through many ways are possible through the medium

When medium particles performs SHM then in that case the wave equation is given as

$y = A sin(\omega t + k x + \phi_0)$

so we have above equation of wave must be sinusoidal equations

so correct answer will be

a. sinusoidal wave

The area of a rectangular loop of wire is 3.6 × 10-3 m2. The loop is placed in a magnetic field that changes from 0.20 T to 1.4

MatroZZZ [7]

Answer:

0.0027 V

0.000625 V

EMF doubles

Explanation:

$B_i$ = Initial magnetic field = 0.2 T

$B_f$ = Final magnetic field = 1.4 T

t = Time taken = 1.6 s

A = Area

N = Number of turns

Induced emf is given by

$E=\frac{N(B_f-B_i)A}{dt}\\\Rightarrow E=\frac{(1.4-0.2)3.6\times 10^{-3}}{1.6}\\\Rightarrow E=0.0027\ V$

Emf is 0.0027 V

$A_i$ = Initial area = $3.6\times 10^{-3}\ m^2$

$A_f$ = Final area = $1.6\times 10^{-3}\ m^2$

B = 0.5 T

Induced emf is given by

$E=\frac{NB(A_f-A_i)}{dt}\\\Rightarrow E=\frac{0.5(1.6\times 10^{-3}-3.6\times 10^{-3})}{1.6}\\\Rightarrow E=-0.000625\ V$

The new emf in the loop will be 0.000625 V (magnitude)

If the number of turns is doubled then the emf doubles as $E\propto N$

Many television sets show 25 images, called 'frames, each second. What is the time interval between one

Firlakuza [10]

Answer:

Given,

Frame rate = 25 frames per second

To find,

Time interval between one frame and the next.

Solution,

We can simply solve this numerical problem by using the following process.

Now,

Number of frames = 25

Total time taken to display the given number of frames (ie. 25 frames) = 1 second

To calculate the time interval between one frame and next, we need to divide the time taken to display total number of frames by total number of frames.

So,

Time interval between one frame and next :

= Time taken to display total number of frames / Total frames

= 1/25

= 0.04 second

Hence, time interval between one frame and next is 0.04 second.
