Answer:
width of fringes are increased
Explanation:
The width of central maxima is given by the following expression
Width = 2 x Dλ / d
- D is distance of screen from source , d is slit width and λ is wavelength of light source.
- Here we see , on d getting decreased , width will increase because d is in denominator .
Due to increased width , position of a fringe moves away from the centre.

You have to find an equation that would relate the two motions of the locomotives. When they meet at a certain point after being 8.5 km apart initially, then that means that their individual distances traveled is equal to 8.5 The solution is as follows:
Distance = speed*time
Total distace = 8.5 = 155t + 155t
Solving for t,
t = 0.027 hour or 98.71 seconds

<span>A portion of the atmosphere that becomes warmer than surrounding air will expand and rise. The warmer atmosphere the more space between the molecules. Therefore, warmer atmosphere </span><span>expands to allow more space for the molecules. Cool air on the other hand, contracts because the molecules in cool air need less space.</span>
