Answer:
width of the slit = a = 0.0935 mm
Explanation:
width of central maximum for single slit diffraction is:
----- (1)
Distance between source and screen = L = 5.5 m
Width of bright band = w = 8 cm
= 0.08 m
λ = 680 nm
Width of the slit = a = ?
Arranging (1) for a
a = 0.0935 mm

Explanation:
Answer:
8.0 seconds
Explanation:
Remember: at the highest point, the ball's velocity is 0.
Given:
Δy = 80 m
v = 0 m/s
a = -9.8 m/s²
Find: t
Δy = vt − ½ at²
(80 m) = (0 m/s) t − ½ (-9.8 m/s²) t²
t = 4.0 s
It takes 4.0 seconds for the ball to reach the highest point. So the ball spends a total of 8.0 seconds in the air.
We know, v = d / t
Here, v = 120 miles/hour
t = 3.5 hour
Substitute their values,
120 = d / 3.5
d = 120 * 3.5
d = 420 miles
In short, Your Answer would be 420 miles
Hope this helps!
In terms of energy, change the angle of the ramp changes the amount of potential energy (increases when the ramp is raised). Potential energy converts to kinetic energy when the ball is released. The more PE, the more KE.
