A horse pulls a cart along a flat road. Consider the following four forces that arise in this situation. (1) the force of the ho

Answer:

(1) - (2)

and

(3) - (4)

Explanation:

Hi!

The Newton's third law states that for every action there's and equal and opposite reaction.

Lets us consider the first force:

<em>(1) the force of the horse pulling on the cart</em>

Therefore, its counterpart, will be a force of the cart pulling on the horse, which is actually:

<em> (2) the force of the cart pulling on the horse</em>

<em />

Analogously, the third force:

<em>(3) the force of the horse pushing on the road</em>

and the fourth force:

<em>(4) the force of the road pushing on the horse </em>

<em />

From a action reaction pair, since the former force acts on the road by the horse, and the latter on the horse by the road

A slit has a width of W1 = 4.4 × 10-6 m. When light with a wavelength of λ1 = 487 nm passes through this slit, the width of the
Vitek1552 [10]

Answer:

The width of the central bright fringe on the screen is observed to be unchanged is 4.48*10^{-6}m

Explanation:

To solve the problem it is necessary to apply the concepts related to interference from two sources. Destructive interference produces the dark fringes.  Dark fringes in the diffraction pattern of a single slit are found at angles θ for which

w sin\theta = m\lambda

Where,

w = width

\lambda =wavelength

m is an integer, m = 1, 2, 3...

We here know that as sin\theta as w are constant, then

\frac{w_1}{\lambda_1} = \frac{w_2}{\lambda_2}

We need to find w_2, then

w_2 = \frac{w_1}{\lambda_1}\lambda_2

Replacing with our values:

w_2 = \frac{4.4*10^{-6}}{487}496

w_2 = 4.48*10^{-6}m

Therefore the width of the central bright fringe on the screen is observed to be unchanged is 4.48*10^{-6}m
