Answer:

TRUE

Explanation:

As we know that position of minimum intensity on the screen at a given angle of the screen is given by equation

a sin\theta = N\lambda

now for width of central maximum we will find the angular width of first minimum

\beta = \frac{2\lambda}{a}

now linear width of the central bright fringe is given as

w = L \beta

w = \frac{2\lambda L}{a}

so we can say that if width of the central fringe will decrease by increasing the width of the slit as they as inversely dependent on each other

So its TRUE

<h3>Why do men and women exhibit different preferences in mate selection?</h3>

Men and women exhibit different preferences in mate selection because both have different attraction cues and priorities for their partner. These cues and priorities leads to difference in preference of life partner.

So we can conclude that Each gender has differing attraction cues and priorities.

Why is temperature scalar?
shepuryov [24]
Temperature is just a measure of how HOT or COLD a substance is, which can be easily defined by a magnitude using a numerical value say “300 K” or “27°C”. Hence we can say it is a scalar quantity.

But the energy which transfer by virtue of a temperature difference is a vector quantity, as it has both magnitude and direction of motion (from High temperature to low temperature region).
