Use: dsin(θ) = mλ where d is slit separation, m is fringe order (1 here), and
θ = 0.183
Now λ = dsin(θ) /m = (0.215e-3)(sin(0.183))/1 = 6.867e-7 or λ = 687.7nm

The next step is -748 divide by -11 is 68 m (answer) the pic got cropped sorry
Answer:
Icy roads
Explanation:
There is so little friction you slide on it way more than other roads. :)
Force, newtons 3rd law of motion stated for every action there is an equal and opposite reaction
Decreasing the distance between two objects having a considerable mass would increase the attraction on gravitation. The reverse is true that if you separate or inrease the objects distance would substantially decrease their gravitational attraction. Most object in our planet is held by its gravitational force towards it's center.
