Answer:

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.

For plate can be given as

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


The type of boot authentication that is more secure is Unified Extensible Firmware Interface
Unified Extensible Firmware Interface help to provide a computer booting that is more secured.
Unified Extensible Firmware Interface is a computer software program that work hand in hand with an operating system, it main function is to stop a computer system from boot with an operating system that is not secured.
For a computer system to boot successfully it means that the Operating system support the Unified Extensible Firmware Interface because it secured.
Inconclusion The type of boot authentication that is more secure is Unified Extensible Firmware Interface

Explanation:
Answer:
Heat gain of 142 kJ
Explanation:
We can see that job done by compressing the He gas is negative, it means that the sign convention we are going to use is negative for all the work done by the gas and positive for all the job done to the gas. With that being said, the first law of thermodynamics equation will help us to solve this problem.
Δ
⇒
Δ

Therefore, the gas gained heat by an amount of 142 kJ.
