Skeletal muscles must have help from the bone to be able to move.
To solve this problem it is necessary to apply the concepts related to interference (destructive and constructive), as well as to the principle of overlap.
By definition we know that constructive interference is defined as
Where,
d = Distance between slits
m = Order interference (Representing the number of repetition of spectrum)
wavelength
Re-arrange the equation to find the angle with the minimum order (m=1) we have,
For the order of the missing interference we can calculate with the spacing of 0.05mm:
Therefore the smallest order interference maximum that is 'missing' from the interference/diffraction pattern on the screen is 5.

Option E:
The mantle
Explanation:
The earth's mantle is the mushy, semi-solid portion of the earth that makes up most of the earth's volume. The mantle extends for a depth of about 2800km downwards into the earth, making it the largest internal portion of the earth. It makes up about 84 percent of the earth's structure, leaving the core and the crust with 15 percent and 1 percent respectively.
Due its nature, convection currents are set up predominantly in the mantle of the earth, which leads to movements in the upper layers of the earth (the crust).
The mantle is large enough for the lighter crust to float on its surface.
