Answer: Got It!
<em>Explanation: </em>let s = speed at launch
v = 0 at top = s sin 63 - g t
so at top
t = s sin 63/g = .0909 s
h = 13.6 = s sin 63 t - 4.9 t^2
13.6 = .081s^2 - .0405 s^2
s^2 = 336
s = 18.3 m/s

Answer:
The spacing between the slits is
Explanation:
From the question we are told that
The wavelength of the light is
The distance of the slit from the screen is
The number of bright fringe is
The length the fringes span is
The fringe width (i.e the distance of between two successive bright or dark fringe) is mathematically represented as
Where d is the distance between the slits
is the fringe width which can also be evaluated as
Substituting values
Making d the subject of formula in the above equation
Substituting values
