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

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

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

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

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

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

(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.

What is the direction of the force for a negative charge moving downward in a magnetic field pointing to the left?

velikii [3]

Answer: A

Out of the screen

Explanation:

Using right hand rule, the magnetic force is perpendicular to the plane form by the magnetic field of a charged particle and its speed. Which will be into the screen.

But the negative charged particle moves in the opposite direction of the positive charged particle. Therefore, the magnetic force direction will be out of the screen

Two transverse waves travel along the same taut string. Wave 1 is described by y1(x, t) = A sin(kx - ωt), while wave 2 is descri

Vadim26 [7]

Answer:

6) Wave 1 travels in the positive x-direction, while wave 2 travels in the negative x-direction.

Explanation:

What matters is the part $kx \pm \omega t$ , the other parts of the equation don't affect time and space variations. We know that when the sign is - the wave propagates to the positive direction while when the sign is + the wave propagates to the negative direction, but <em>here is an explanation</em> of this:

For both cases, + and -, after a certain time $\delta t$ ( $\delta t >0$ ), the displacement <em>y</em> of the wave will be determined by the $kx\pm\omega (t+\delta t)$ term. For simplicity, if we imagine we are looking at the origin (x=0), this will be simply $\pm \omega (t+\delta t)$ .

To know which side, right or left of the origin, would go through the origin after a time $\delta t$ (and thus know the direction of propagation) we have to see how we can achieve that same displacement <em>y</em> not by a time variation but by a space variation $\delta x$ (we would be looking where in space is what we would have in the future in time). The term would be then $k(x+\delta x)\pm\omega t$ , which at the origin is $k \delta x \pm \omega t$ . This would mean that, when the original equation has $kx+\omega t$ , we must have that $\delta x>0$ for $k\delta x+\omega t$ to be equal to $kx+\omega\delta t$ , and when the original equation has $kx-\omega t$ , we must have that $\delta x$ for $k\delta x-\omega t$ to be equal to $kx-\omega \delta t$

<em>Note that their values don't matter, although they are a very small variation (we have to be careful since all this is inside a sin function), what matters is if they are positive or negative and as such what is possible or not .</em>

<em />

In conclusion, when $kx+\omega t$ , the part of the wave on the positive side ( $\delta x>0$ ) is the one that will go through the origin, so the wave is going in the negative direction, and viceversa.

Laskar, J.: 1990, The chaotic motion of the solar system. A numerical estimate of the size of the chaotic zones, Icarus, 88, 266

balandron [24]

The chaotic nature of the Solar System excluding Pluto was established by the numerical computation of the maximum Lyapunov exponent of its secular system over 200 myr.

<h3>What is chaotic motion of the solar system ?</h3>

There has been an increase in awareness of chaotic dynamics in the solar system over the past 20 years. The orbits of tiny objects in the solar system, such as asteroids, comets, and interplanetary dust, are now known to be chaotic and to experience significant variations across geological time periods.

a completely unpredictable orbit, or one where significant changes in the orbit can result from even small changes in the position and/or velocity of the orbiting entity.
