A 0.106-A current is charging a capacitor that has square plates 4.60 cm on each side. The plate separation is 4.00 mm.

nikdorinn [45]

Answer:

a

$\frac{d \phi_{E}}{dt} =1.1977 *10^{10} \ V\cdot m/s$

b

$I = 0.106 \ A$

Explanation:

From the question we are told that

The current is $I = 0.106 \ A$

The length of one side of the square $a = 4.60 \ cm = 0.046 \ m$

The separation between the plate is $d = 4.0 mm = 0.004 \ m$

Generally electric flux is mathematically represented as

$\phi_E = \frac{Q}{\epsilon_o}$

differentiating both sides with respect to t is

$\frac{d \phi_{E}}{dt} = \frac{1}{\epsilon_o} * \frac{d Q}{ dt}$

=> $\frac{d \phi_{E}}{dt} = \frac{1}{\epsilon_o} *I$

Here $\epsilon_o$ is the permitivity of free space with value

$\epsilon _o = 8.85*10^{-12} C/(V \cdot m)$

=> $\frac{d \phi_{E}}{dt} = \frac{0.106}{8.85*10^{-12}}$

=> $\frac{d \phi_{E}}{dt} =1.1977 *10^{10} \ V\cdot m/s$

Generally the displacement current between the plates in A

$I = 8.85*10^{-12} * 1.1977 *10^{10}$

=> $I = 0.106 \ A$

What are examples of devices that use electromagnetic waves? Check all that apply.

yKpoI14uk [10]

Well, there aren't actually ANY that apply, because you haven't listed any. But I've lived a long time, and I remember hearing about electromagnetic waves and things that use them, so I can list a FEW of them for you:

-- radios

-- TVs

-- garage-door openers

-- TV remotes

-- cell phones

-- smart phones

-- GPS

-- walkie-talkies

-- car headlights

-- lava lamps

-- toasters

-- LEDs

-- light bulbs

-- fluorescent light tubes

-- police radios

-- Doppler weather radars

-- CB radios

-- ham radios

-- neon signs

-- eyeglasses

-- microscopes

-- telescopes

-- gas stoves

-- electric stoves

-- wood stoves

-- microwave ovens

-- tanning beds

-- cameras

-- lasers

-- CD recorders and players

-- DVD recorders and players

-- Bluray recorders and players

-- movie cameras

-- movie projectors

-- reading lamps

-- candles

-- whale-oil lamps

-- kerosene lanterns

-- flashlights

-- campfires

-- coffee percolators

-- heat lamps

-- cordless phones

These are just the ones I can think of right now off the top of my head. There are a lot of others.

Two harmonic waves traveling in opposite directions interfere to produce a standing wave described by y = 3 sin (2x) cos 5t wher

Nostrana [21]

Answer:

The wavelength of the interfering waves is 3.14 meters.

Explanation:

Given that,

The equation of standing wave that is formed by interfering two harmonic waves (travelling opposite direction) is given by :

$y=3\ sin(2x)\ cos(5t)$ ........(1)

The general equation of standing wave is given by :

$y=2A\ sin(kx)\ cos(\omega t)$ ..............(2)

On comparing equation (1) and (2), we get :

k = 2

We know that,

$\dfrac{2\pi}{\lambda}=k$

$\dfrac{2\pi}{\lambda}=2$

$\lambda=3.14\ m$

So, the wavelength of the interfering wave is 3.14 meters. Hence, this is the required solution.
