Three large plates are separated bythin layers of ethylene glycol and water. The top plate moves to the right at 2m/s. At what speed and in what direction must the bottom plate be moved to hold the center plate stationary?

speed = 0.17m/s

Explanation:

For water at 20°c,

For ethylene glycol at 20°c,

Shear stress due to motion of the upper plates:

;

= u(v/b)

;

Therefore, for the middle plate to be stationery, the bottom plate must move to the left at a speed that produces equal oppostite force.

Therefore,

;

;

To find V we have

V= 0.17m/s

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
