The actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.
<h3>Wavelength of the light</h3>
The wavelength of the light is determined using the following formulas;
where;
- λ is wavelength
- d is width of the slit
- D is the distance of the screen
- y is distance between the central bright fringe and dark fringe
<h3>Actions that would decrease the width of the central bright</h3>
y = (λD) / (d)
- Decrease in the wavelength of the light
- Increase in the width of the slit
Thus, the actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.

The formula for potential energy is mass x height x gravitational force. Your mass is 5.3 kg and your height is 6.6 meters. The gravitational force on earth is 9.8 m/s. That means your answer is 5.3 x 6.6 x 9.8 and that equals 342.804
Answer:
0.333 m/s
Explanation:
avg speed= (total distance)/(total time)
10m/30s
0.333 m/s
Let be the height of the building and thus the initial height of the ball. The ball's altitude at time is given by
where is the acceleration due to gravity.
The ball reaches the ground when after . Solve for :
so the building is about 16 m tall (keeping track of significant digits).
