The distance y3,red from the center of the pattern to the location of the third diffraction minimum of the red laser is 4.05 cm.
oksian1 [2.3K]

Answer:

L = a 1,929 10⁴ m

a = 0.1 mm = 0.1 10⁻³ m,     L = 1,929 m

Explanation:

The diffraction phenomenon is described by the expression

       a sin θ = m λ

Let's use trigonometry to find the breast

        tan θ = y / x

As the angles are very small

       tan θ = sin θ/ cos θ = sin θ = y / x

We replace

        a y / L = m λ

        L = a y / m λ

The red light has a wavelength of Lam = 700 nm = 700 10⁻⁹ m, in the third pattern it is m = 3

       L = a  4.05 10⁻² / (3 700 10⁻⁹)

       L = a 1,929 10⁴ m

To give a specific value we must know the width of the slit, suppose a value of  a = 0.1 mm = 0.1 10⁻³ m

       L = 1,929 m

1. Apply a constant force of 50 N directed to the right of the 50 kg Box. (2 pts)
kotegsom [21]

As the box is moving with a constant velocity, the two forces acting on the box are canceling each other.

Then   friction force = 80 Newtons              but in the opposite direction.

Friction force =  Mu  * Normal force exerted by ground  =  Mu * weight of box

So we find Mu.

Mu = coefficient of friction between box and horizontal surface

          = Force of friction / weight  =  80 / 50 * 9.81 = 0.163

When an identical box is placed on top, the force of friction is

      = Mu * total weight = 0.163 * (50+50) * 9.81 = 159.9 Newtons

Which forces tend to slow down an object
laila [671]
The answer is "friction and air resistance" gravity does some of the work by keeping the object from floating away, but friction and air resistance does the biggest part. Friction is how rough the ground it meaning on tile, dirt, grass, etc... that would slow down the object and air resistance is the gravity pushing on the object also making it stop. 

Hope this helps!
