Answer:
The Mach number is 2.866
Total temperature To = 528.524K
Explanation:


Temperature (T) = 200K
For air, r= 1.4
To find the Mach number we use:
![Po/P = [1 + (r - 1/2) M^2] ^ r^/^r^-^1](https://tex.z-dn.net/?f=%20Po%2FP%20%3D%20%5B1%20%2B%20%28r%20-%201%2F2%29%20M%5E2%5D%20%5E%20r%5E%2F%5Er%5E-%5E1%20)
![1.5 * 10^6 / 5 * 10^4 =[ 1 + (1.4 -1 /2) (M^2) ] ^ 1^.^4^/^1^.^4^-^1](https://tex.z-dn.net/?f=%201.5%20%2A%2010%5E6%20%2F%205%20%2A%2010%5E4%20%3D%5B%201%20%2B%20%281.4%20-1%20%2F2%29%20%28M%5E2%29%20%5D%20%5E%201%5E.%5E4%5E%2F%5E1%5E.%5E4%5E-%5E1%20)




1.6426 = 0.2M^2


M = 2.866
To find Total Temperature :
![To/T = (Po/P)^r^-^1^/^8) [tex][tex] To/200 = (1.5*10^6 / 5*10^4)^ 1^.^4^-^1^/^1^.^4)](https://tex.z-dn.net/?f=%20To%2FT%20%3D%20%28Po%2FP%29%5Er%5E-%5E1%5E%2F%5E8%29%20%5Btex%5D%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%5Btex%5D%20To%2F200%20%3D%20%281.5%2A10%5E6%20%2F%205%2A10%5E4%29%5E%201%5E.%5E4%5E-%5E1%5E%2F%5E1%5E.%5E4%29%20)

To =528.524K
A design brief should highlight the problem and specifications for the solution.
<h3>What is an electrical circuit?</h3>
An electrical circuit can be defined as an interconnection of different electrical components, in order to create a pathway for the flow of electric current (electrons) due to a driving voltage.
<h3>The components of an electrical circuit.</h3>
Generally, an electrical circuit comprises the following electrical components:
<h3>What is a design brief?</h3>
A design brief can be defined as a short statement which is written to describe the need of an individual or business, and what type of solution will meet that need (problem) through the design of an electrical circuit.
This ultimately implies that, a design brief should highlight the problem and specifications for the solution.

Explanation:
Conduction:
Heat transfer in the conduction occurs due to movement of molecule or we can say that due to movement of electrons in the two end of same the body. Generally, phenomenon of conduction happens in the case of solid . In conduction heat transfer takes places due to direct contact of two bodies.
Convection:
In convection heat transfer of fluid takes place due to density difference .In simple words we can say that heat transfer occur due to motion of fluid.
