The formula for accelerational displacement is at^2/2, so we know that 3.9t^2/2 = 200, or 3.9t^2 = 400. t =

, at = v, so
Answer:
1524 nm.
Explanation:
Angular separation of n th minima is given by the expression
Sin θ = n λ / a
Where λ is wavelength of light used and a is separation between two slits .
a = n λ / sin θ
For a to be minimum, sinθ has to be maximum .
maximum value of sin of any angle is 1 .
so the relation becomes as follows
a = n λ
n = 2 , λ = 762 nm.
a = 2 x 762 nm
= 1524 nm.
Answer: Speed
Explanation:
Speed is the time it takes something to travel a certain distance. Accelaration is the rate at which an object's speed changes. Velocity is a vector of the object's speed and direction.
