I'm not sure if there's some fancy thing you have to do, but if there's no cardinal compass given, I think it's safe to assume that the answer is based off of one. Therefore, up is north, right is east, so Maple Creek flows to the northeast.
However, if they do give you one where, say, north points downwards, the creek would flow to the southwest. But again, from what is shown, there's no compass, so NE is your best guess here.
Sound waves travel through the air, liquids, and solids. they transfer energy from the source of the sound to its surroundings
Answer:
The (minimum) thickness of the oil slick is 325 nm.
Explanation:
Let the (minimum) thickness of the oil slick =
Therefore:
2 = (+)*λ/ (1)
similarly,
2=()*λ/ (2)
Thus, equation 1 = equation 2
(+*λ = (*λ
Where:
λ
λ
Therefore:
=650/390=5/3
This shows that,
=2
=1
Thus, using equation 2
=
