Answer:
- "Newton’s viscosity law’s states that, the shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers".
- A non-Newtonian fluid is a fluid which the relationship between the shear stress and the velocity gradient is not properly defined by the Newton's viscosity law, thus, the behavior is not lineal but potential.
Explanation:
Hello, here the answers:
- "Newton’s viscosity law’s states that, the shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers" (taken from Kundu, P. K., Cohen, I. M., & Dowling, D. R. (2012). Fluid mechanics.), thus, it means that when you have a fluid with an acting-on-it share stress (an external force which move the fluid), the related velocity gradient (variation or change in velocity) at which the layers are moving are related as:
Whereas 
is the shear stress, 
is the viscosity and the differential accounts for the change in the velocity in the arbitrary 
coordinate.
- A non-Newtonian fluid is a fluid which the relationship between the shear stress and the velocity gradient is not properly defined by the Newton's viscosity law, thus, the behavior is not lineal but potential, based on:
Whereas 
accounts for a decreasing or increasing behavior of the shear stress.
Best regards.
Explanation:
The electromagnetic spectrum shows the wavelength or frequency range of different waves starting from gamma rays to radio waves.
In the electromagnetic spectrum, gamma rays have shorter wavelength while radio wave have longest wavelength.
The correct order is as follows :
(A) Gamma rays
(B) X rays
(C) Ultraviolet
(D) Visible light
(E) Infrared waves
(F) Radio waves
So, the correct order form left to right in order of increasing wavelength is as follows :
Gamma rays < X rays < Ultraviolet < Visible Light < Infrared Waves < Radio Waves

<em>Answer:</em>
- Pivalic acid forms a strong conjugate base.
<em>Explanation:</em>
- Strong acid has weak conjugate base
- Weak acid has strong conjugate base
As in this case, pivalic acid is weak acid (Due to electron donating effect of <em>tert.</em> butyl group) having pka value of 5.0 , so its conjugate base will be strong as compare to formic acid which is stronger acid.
<em>Summary: </em>
- As pivalic acid is weak acid as compare to formic acid, so its conjugate base will be strong and vice versa.
