Answer:
The objective of a protection scheme is to keep the power system stable by isolating only the components that are under fault, whilst leaving as much of the network as possible still in operation.
Explanation:
The devices that are used to protect the power systems from faults are called protection devices.
The EMV - Ending Market Value is given as:
$2,400,000.
<h3>How is the EMV Arrived At?</h3>
The EMV is given as:
BMV x (i + r); Where
BMV is the Beginning Market Value; and
r is the interest rateor percentage given.
Hence the EMV = 2,000,000 x ( 1 + 20%)
= 2,000,000 x 1.2
= $ 2, 400,000.
It is to be noted that the BMV is the Beginning Market Value which is the value of an investment at the start of the business period.

Answer
C02 cartridges are compressed.
Explanation:
The C02 Cartridge will be used to power our dragsters by the compression inside of the bottle. Since C02 is a compressed gas inside of a small container, The pressure when released my provide enough force to move the dragster at high speeds. An example of this would be like an air soft gun. some air soft guns are used by small C02 Cartridges, which let out a strong burst of compressed C02, which fires the projectiles at very high speeds.
Answer:
i) 43.55 kg/s
ii) 40 m/s
iii) -199.32 KW
Explanation:
To resolve the above question we have to make some assumptions :
- mass flow through the system is constant
- The only interactions that are between the system and the surrounding are work and heat
- The fluid is uniform
i) first we have to determine the mass flow rate of the air
M = 
= 
---------- (1) hence M = 43.55 kg/s
ii) using this relationship : A1V1 = A2V2 hence V1 = (0.2/0.5) * 100 = 40m/s ( inlet velocity )
input this value into equation 1
iii) Next we will determine the power required to run compressor
attached below
power required = -199.32 KW ( this value indicates that there is power supplied )
