Answer:
an example is a bicep curl
Explanation:
A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move an object.
Answer:
The the intensity at an 11° angle to the axis in terms of the intensity of the central maximum is

Explanation:
From the question we are told that
The width of the slit is 
The wavelength is 
The angle is 
The intensity of at
to the axis in terms of the intensity of the central maximum. is mathematically represented as
![I_c = \frac{I}{I_o} = [ \frac{sin \beta }{\beta }] ^2](https://tex.z-dn.net/?f=I_c%20%3D%20%5Cfrac%7BI%7D%7BI_o%7D%20%20%3D%20%5B%20%5Cfrac%7Bsin%20%5Cbeta%20%20%7D%7B%5Cbeta%20%7D%5D%20%5E2)
Where
is mathematically represented as

substituting values


So
![I_c = \frac{I}{I_o} = [ \frac{sin (708.1) }{(708.1)}] ^2](https://tex.z-dn.net/?f=I_c%20%3D%20%5Cfrac%7BI%7D%7BI_o%7D%20%20%3D%20%5B%20%5Cfrac%7Bsin%20%28708.1%29%20%20%7D%7B%28708.1%29%7D%5D%20%5E2)
