Answer:
The skier's change in velocity is 7.69 meters per second.
Explanation:
The Newton's second law tells force is equal to the change on the linear momentum of a body:

If we approximate the differential
to
:

Using that linear momentum is mass times velocity:

Solving for
:


Answer:
Explanation:
distance between two slit d = 
d = 18.15 x 10⁻⁷ m
Let wave length of light λ
formula for position of first pair of bright spot
Tanθ = λ / d , λ is wave length of light and d is distance between two slit .
Tan 15.4 = 
λ = Tan 15.4 x 18.15 x 10⁻⁷
=5 x 10⁻⁷ m
If θ be the position of next bright spot
Tanθ = 2 λ / d
= 
=
θ = 28.4 degree .
Answer:

In Euclidean geometry parallel lines never intersect. But in non-Euclidean geometry parallel lines can either curve away from each other, or curve towards each other. Example : the black lines that wrap themselves around the basketball.
Answer: B ) non-Euclidean
