Light with a wavelength of 612 nm incident on a double slit produces a second-order maximum at an angle of 25 degree. What is th

erastova [34]

Answer:

Speration between the slits $d=2.86\ \mu m$

Explanation:

Given that,

Wavelength of light, $\lambda=612\ nm=612\times 10^{-9}\ m$

It is incident on a double slit produces a second-order maximum at an angle of 25 degree.

The condition for maxima is given as :

$dsin\theta=m\lambda$

d = seperation between the slits

m = order, m = 2

$d=\dfrac{m\lambda}{sin\theta}$

$d=\dfrac{2\times 612\times 10^{-9}\ m}{sin(25)}$

d = 0.00000289

$d=2.86\mu m$

So, the seperation between the silts is $2.86\ \mu m$ . Hence, this is the required solution.

Determine the moment of inertia of a 14.8 kg sphere of radius 0.752 m when the axis of rotation is through its center.

vfiekz [6]

Answer:

$I=3.348Kgm^2$

Explanation:

From the question we are told that:

Mass $m=14.8kg$

Radius $r=0.752m$

Generally the equation for inertia is mathematically given by

$I=\frac{2}{5}mR^2$

$I=\frac{2}{5}14.8*(0.752)^2$

$I=3.348Kgm^2$

What are the effects of overpopulation on a specific species in an ecosystem?

bagirrra123 [75]

Tere would be too many so there would be more fighting. Thye could overpopulate the world and destroy our stuff for example if it is a pig they can easily destory crops. We would all have to go hunting. There would also be less food so that is why they would start going out and destroying stuff.
