How you would orient the magnets and what you would do with the magnets to achieve maximum repulsion

1 answer:

3 0

The orientation of the magnets that gives the strongest repulsion because these poles and facing each other that is then leaves highest flux density of the poles for a force of repulsion to be very high

Using a 679 nm wavelength laser, you form the diffraction pattern of a 1.1 mm wide slit on a screen. You measure on the screen t

sveta [45]

To solve the problem, apply the concepts related to constructive and destructive interference. For this purpose, we will start by defining the distance from the dark fringe from the central maximum in terms of the slit separation, the number of fringe the wavelength and the distance of the screen to the slit. Mathematically this is,

$y_n = \frac{(2n-1)\lambda D}{2d}$

$D = \frac{2dy_n}{(2n-1)\lambda}$

Here,

d = Slit separation

n = Number of fringe

$y_n$ = Distance of the dark fringe from the central maximum

D = Distance of the screen to the slit

$\lambda$ = Wavelength

Our values are given as,

$\lambda = 679nm = 679*10^{-9}m$

$d = 1.1mm = 1.1*10^{-3}m$

$y_{14} = 8.01cm = 8.01*10^{-2} m$

$n = 14$

Replacing,

$D = \frac{2(1.1*10^{-3})(8.01*10^{-2})}{(2(14)-1)(679*10^{-9})}$

$D = 9.61m$

Therefore the screen is located from the slit to 9.61m

How can gases have such a large impact on earths atmosphere

kozerog [31]

Answer:

well, the air in our atmosphere stays there and nothing can get past the last layer. Think of is as a car. if there gets to be too much gas in it, it can harm you. I would also say it is one of the causes of global warming. Also air pollution is a big problem.

The diagram below shows a light ray striking Medium A and Medium B at the same angle.

zepelin [54]

Answer: D Medium B is denser than Medium A because light bends more in Medium B.

Explanation: The more the light bends the less energy it has
