Answer:

Explanation:

Given

Mass of block A (m_a)=2.6 kg

Mass of block B (m_b)=0.81 kg

Force of 6.5 N is applied on Block A

Force on Block A is F, Tension

thus

F-T=m_a\times a -----1

where a=acceleration of the system

For Block B

T=m_b\times a -----2

F=m_b\times a+m_a\times a

F=\left ( m_a+m_b\right )a

F=\left ( 2.6+0.81\right )a

a=\frac{6.5}{3.41}

a=1.96 m/s^2

T=0.81\times 1.96=1.54 N

Light of wavelength 560 nm passes through a slit of width 0. 170 mm. (a) the width of the central maximum on a screen is 8. 00 m
faltersainse [42]

The distance between slit and the screen is 1.214m.

To find the answer, we have to know about the width of the central maximum.

<h3>How to find the distance between slit and the screen?</h3>
  • It is given that, wavelength 560 nm passes through a slit of width 0. 170 mm, and the width of the central maximum on a screen is 8. 00 mm.
  • We have the expression for slit width w as,

                           w=\frac{2*wavelength*d}{a}

where, d is the distance between slit and the screen, and a is the slit width.

  • Thus, distance between slit and the screen is,

                           d=\frac{w*a}{2*wavelength} =\frac{8*10^{-3}*0.17*10^{-3}}{560*10^{-9}*2} \\\\d=1.214m

Thus, we can conclude that, the distance between slit and the screen is 1.214m.

How do you know the speed of an electromagnetic wave in a vacuum?
ycow [4]
Electromagnetic waves need no matter to travel - they can travel through empty space (a vacuum). In a vacuum, all electromagnetic waves travel at approximately 3 x 108 m/s - which is the fastest speed possible. ...
Light traveling value through an optical Fibre is, 2 x 108 m/s. Hope that helps.
