In order to understand a monomer let´s first see the structure of a polymer. As an example, in the first figure polyethylene (or polyethene) is shown. This polymer, like every other one, is composed of many repeated subunits, these subunits are called monomer. In the second figure, polyethylene's monomer is shown.

Prompt the user to enter five numbers, being five people's weights. Store the numbers in an array of doubles. Output the array's
atroni [7]

Answer:

See below in the explanation section the Matlab script to solve the problem.

Explanation:

prompt='enter the first weight w1:  ';

w1=input(prompt);

wd1=double(w1);

prompt='enter the second weight w2:  ';

w2=input(prompt);

wd2=double(w2);

prompt='enter the third weight w3:  ';

w3=input(prompt);

wd3=double(w3);

prompt='enter the fourth weight w4:  ';

w4=input(prompt);

wd4=double(w4);

prompt='enter the first weight w5:  ';

w5=input(prompt);

wd5=double(w5);

x=[wd1 wd2 wd3 wd4 wd5]

What are the units or dimensions of the shear rate dv/dy (English units)? Then, what are the dimensions of the shear stress τ= μ
swat32

Answer:

1) Dimensions of shear rate is [T^{-1}] .

2)Dimensions of shear stress are [ML^{-1}T^{-2}]

Explanation:

Since the dimensions of velocity 'v' are [LT^{-1}] and the dimensions of distance 'y'  are [L] , thus the dimensions of \frac{dv}{dy} become

\frac{[LT^{-1}]}{[L]}=[T^{-1}] and hence the units become s^{-1}.

Now we know that the dimensions of coefficient of dynamic viscosity \mu are [ML^{-1}T^{-1}] thus the dimensions of shear stress can be obtained from the given formula as

[\tau ]=[ML^{-1}T^{-1}]\times [T^{-1}]\\\\[\tau ]=[ML^{-1}T^{-2}]

Now we know that dimensions of momentum are [MLT^{-1}]

The dimensions of Area\times time are [L^{2}T]

Thus the dimensions of \frac{Moumentum}{Area\times time}=\frac{MLT^{-1}}{L^{2}T}=[MLT^{-2}]

Which is same as that of shear stress. Hence proved.

In multi-grade oil what is W means?
irga5000 [103]

Answer:

winter viscosity grades

Explanation:

The “W”/winter viscosity grades describe the oil's viscosity under cold temperature engine starting conditions. There's a Low Temperature Cranking Viscosity which sets a viscosity requirement at various low temperatures to ensure that the oil isn't too thick so that the starter motor can't crank the engine over.
