Light of wavelength 510 nm is used to illuminate normally two glass plates 24.3 cm in length that touch at one end and are separ
bulgar [2K]

Answer:

m = 180 \ bright \ fringes

Explanation:

From the question we are told that

    The  wavelength is  \lambda  =  510 \ nm = 510 *10^{-9} \  m

    The length of the of the plate is  l  =  24.3 \ cm  =  0.243 \  m

    The radius of the wire  is r=  0.023 \ mm  =  2.3 *10^{-5} \ m

Generally the diameter of the wire which is the distance between the glass  plates is mathematically represented as

             d =  2 *   r

=>          d =  2 *   2.3 *10^{-5}

=>          d =  4.6 *10^{-5} \  m

 Generally the condition for constructive interference is mathematically represented as

           2 *d = m \lambda

=>        m = \frac{2d}{\lambda}

=>        m = \frac{2 * (4.6* 10^{-5})}{ 510 *10^{-9} }

=>        m = 180 \ bright \ fringes

A bowling ball has an initial momentum of +30 kg m/s and hits a stationary bowling pin. After the collision, the bowling ball le
dangina [55]

Momentum should be conserved. The momentum of both objects must balance with their initial and final momentum.

Let m1 and v1 be the mass and velocity of the bowling ball

And m2 and v2 be the mass and velocity of the bowling pin

(m1v1)i + (m2v2)i = (m1v1)f + (m2v2)f

30 kg m/s + (1.5 kg)(0 m/s) = 13kg m/s + 1.5v2f

V2f = 11.33 m/s

<span>So the momentum = 1.5 kg(11.33 m/s) = 17 kg m/s</span>
