Component ' W ' is the standard schematic symbol for a switch.

The short line between the two circles can be shown straight,
like it is now, when the switch is 'closed' and current can flow.

Or, it can also be drawn slightly tilted, so it's not touching one
of the circles. In that case, the switch is 'open', no current can
flow through it, and the whole circuit is shut down.

The displacement y is expressed as a function of x and t in terms of the wave numberk and the angular frequency. Write the equiv

Phoenix [80]

Explanation:

The displacement equation is given by :

(a) $y=A\ sin(\omega t\pm kx)$

Since, $\omega=2\pi f$

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

$y=A\ sin(2\pi f t\pm kx)$

$y=A\ sin(\dfrac{2\pi vt}{2\pi /k}\pm kx)$

$y=A\ sin(kvt+kx)$

$y=A\ sink(vt+x)$

The above equation is in terms of k and v.

(b) $y=A\ sin(\omega t\pm kx)$

$y=A\ sin(2\pi \dfrac{v}{\lambda}t\pm\dfrac{2\pi}{\lambda}x)$

$y=Asin\dfrac{2\pi}{\lambda}(vt\pm x)$

$y=A\ sin(2\pi f t\pm \dfrac{2\pi}{\lambda} x)$

$y=A\ sin\ 2\pi (ft\pm \dfrac{x}{\lambda})$

(d) $y=A\ sin(\omega t\pm kx)$

$y=A\ sin(2\pi ft+\dfrac{2\pi}{\lambda}x)$

$y=A\ sin(2\pi ft+\dfrac{2\pi}{v/f}x)$

$y=A\ sin\ 2\pi f(t+\dfrac{x}{v})$

Where

k is the propagation constant

v is the speed of wave

f is the frequency of a wave

$\lambda$ is the wavelength

Hence, this is the required solution.

NO LINKS: Which of the following best demonstrates Newton's Third Law?

irina1246 [14]

The best demonstration that applies to Newton's Third Law of motion would be D) When you walk your foot pushes down on the ground while the ground pushes back on your foot.

------------------

Newton's Third Law states that for every action, there is an equal and opposite reaction. This is actually explains that forces come in pairs and forces are an interaction between two objects. As per the correct option given in the question explains Newton’s Third Law.

------------------

When you walk your foot (say object A) pushes down on the ground while the ground (say object Q) pushes back on your foot with the same force but in the opposite direction.
