I can only offer you one which is mushroom. They're fungus' and they can't produce their own food. They get their food from decaying and dead animals and absorb it through their roots.
If all the sides are equal, then it is an equilateral triangle. This means after walking 100 meters, you had to turn 1/3 of 180 degrees (because that's what the interior angles of the triangle add up to).
So, 180 * 1/3 = 60 degrees.
We aren't done yet.
60 degrees is not the angle which you have turned from your path.
You turned 120 degrees to describe an angle of 60 degrees on the interior side.
The answer is B.
Answer:
30 cm
Explanation:
Hi! Lets find the angles for the first and second order maxima
The first order maximum will occur for Ф=0
The second order maximum will satisfy the following relationship:
sinФ = λ/d
Where λ = 600 x 10^-9 m and d = 5 x 10^-5 m
Therefore:
sinФ = 0.012
And the vertical distance bewteen the first and second will be given by:
l = (2.5 m) tanФ
But since 2.5 m>>0.05 mm ; sinФ≈tanФ
Therefore:
l = (2.5 m) sinФ
l = 0.03 m = 30 cm
