Answer:
i think your question is incomplete. try including all data
Explanation:
A. To solve for part A, we use the formula of Young’s
double slit equation:
x = λ L m / d<span>
</span>Where,
x = distance between adjacent dark lines or fringes =
12.5 cm = 0.125 m
λ = wavelength of light = 600 × 10^-9 m
L = distance from the two sources of light to
the screen = 1.2 m
m = number of fringes = 10 (tenth) – 1 (first)
= 9
d = separation of slits = unknown
Rearranging the equation in terms of d and
plugging in the values:
d = λ L m / x
d = (600 × 10^-9 m) (1.2 m) (9) / 0.125 m
d = 5.184 × 10^-5 m
d = 51.84 μm
B. The formula for path difference is:
path difference = (2 m + 1) (λ / 2)<span>
path difference = (2 * 9 + 1) (</span>600 × 10^-9 m / 2)
<span>path
difference = 5.7 × 10-6 m</span>
<span>path difference = 5.7 μm</span>

Answer:
a = 200 m/s²
Explanation:
Given,
The initial speed of rocket-powered sled, u = 0
The final speed of rocket-powered sled, v = 440 m/s
Time taken to reach final speed, t = 2.20 s
The acceleration of the body is given by the change in velocity by time
a = (v - u) / t
= (440 - 0) / 2.20
= 200 m/s²
Therefore, the acceleration of the rocket-powered sled, a = 200 m/s²
