Lynna [10]

Answer:

250 N/m2

Explanation:

Shear stress on cells lining the walls of the blood vessels  is equal to 2020 dyne/cm2

In terms of Newton/square meter, shear stress is equal to

20*\frac{dyne}{cm^2}  (\frac{10^{-5}N}{1 dyne} )*(\frac{1 cm^2}{10^{-4}*m^2} )\\= 2.0 N/m2

Shear modulus is equal to shear stress divided by shear strain

Thus, shear modulus is equal to

= \frac{2.0}{0.008} \\= 250N/m2

AleksAgata [21]

Answer:

A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties

A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity

Many scientists claim plants are more complex than animals based on the differences in plant and animal cells. What evidence can
gayaneshka [121]

The plant cells are more complex because it has more structures like the cell wall and chloroplast.

Plant cells can be larger than animal cells. The normal range for an animal cell varies from 10 to 30 micrometers while that for a plant cell stretches from 10 to 100 micrometers. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.

Hope this helps.
