Answer:
It made information easily accessible and ensured individuals became more vast in subject topics of interest.
Explanation:
Information revolution is different and unique and it came with the advent of computers and the internet. A lot of information is stored there which is too large and complex for the human brain.This helped people to access information without much stress as informations about almost every subject is on the Internet.
Individuals can check the informations up and become more vast in interested topics.
5-6 feet is 60-72 inches and 8 feet is 96 inches
Answer:
![Re=\dfrac{\rho\ v\ l}{\mu }](https://tex.z-dn.net/?f=Re%3D%5Cdfrac%7B%5Crho%5C%20v%5C%20l%7D%7B%5Cmu%20%7D)
Explanation:
Reynolds number:
Reynolds number describe the type of flow.If Reynolds number is too high then flow is called turbulent flow and Reynolds is low then flow is called laminar flow .
Reynolds number is a dimensionless number.Reynolds number given is the ratio of inertia force to the viscous force.
![Re=\dfrac{F_i}{F_v}](https://tex.z-dn.net/?f=Re%3D%5Cdfrac%7BF_i%7D%7BF_v%7D)
For plate can be given as
![Re=\dfrac{\rho\ v\ l}{\mu }](https://tex.z-dn.net/?f=Re%3D%5Cdfrac%7B%5Crho%5C%20v%5C%20l%7D%7B%5Cmu%20%7D)
Where ρ is the density of fluid , v is the average velocity of fluid and μ is the dynamic viscosity of fluid.
Flow on plate is a external flow .The values of Reynolds number for different flow given as
![Reynolds\ number\is \ >\ 5 \times 10 ^5\ then\ flow\ will\ be\ turbulent.](https://tex.z-dn.net/?f=Reynolds%5C%20number%5Cis%20%5C%20%3E%5C%205%20%5Ctimes%2010%20%5E5%5C%20then%5C%20flow%5C%20will%5C%20be%5C%20turbulent.)
![Reynolds\ number\is \](https://tex.z-dn.net/?f=Reynolds%5C%20number%5Cis%20%5C%20%3C%5C%205%20%5Ctimes%2010%20%5E5%5C%20then%5C%20flow%5C%20will%5C%20be%5C%20laminar.)
Answer: 5.36×10-3kg/h
Where 10-3 is 10 exponential 3 or 10 raised to the power of -3.
Explanation:using the formula
M =JAt = -DAt×Dc/Dx
Where D is change in the respective variables. Insulting the values we get,
=5.1 × 10-8 × 0.13 × 3600 × 2.9 × 0.31 / 4×10-3.
=5.36×10-3kg/h
