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:
Your question lacks the time required hence i will calculate the Average flow rate using a general concept and an assumed time value of 25 seconds
ANSWER : 104.904 ft^3/sec
Explanation:
General concept : Average flow rate is the volume of fluid per unit time through an area
Hence the average flow rate of the air conditioning unit of this room
Volume of the room / time taken for the air to cycle the room = v / t
assuming the time taken = 25 seconds
volume of room = width * length * height
= 14.1 * 15.5 * 12 = 2622.6 ft^3
Average flow rate = V/ t
= 2622.6 / 25 = 104.904 ft^3/sec
Answer:
C. Welded contacts on the thermostat
Explanation:
Any fault that keeps the heating element heating when it should not is a fault that will cause the symptom described. The details <em>depend on the design of the brewer</em> (not given).
"A short at the terminals" depends on what terminals are being referenced. The device on-off switch terminals are normally connected together when the brewer is turned on, so a short there may not be observable.
"Welded contacts on the thermostat" will have the observed effect if the thermostat is the primary means of ending the brewing cycle. If the thermostat of interest is an overheat protective device not normally involved in ending the brewing cycle, then that fault may not cause the observed symptom.
__
If the heating element is open-circuit, no heating will occur. A gasket leak may cause a puddle, but may have nothing to do with the end of the brewing cycle. (Loss of water can be expected to end boiling, rather than prolong it.)
Answer: a) Efficiency = 0.92
b) V = 319.19 m/s
c) S = 0.012 kj/kg.k

Answer:
1st Harmonic:

3rd Harmonic:

5th Harmonic:

7th Harmonic:

Explanation:
The general form to represent a complex sinusoidal waveform is given by

Where A is the amplitude in volts of the sinusoidal waveform
Where f is the frequency in cycles per second (Hz) of the sinusoidal waveform
Where
is the phase angle in radians of the sinusoidal waveform.
1st Harmonic:
We have A = 50, f = 1000 and φ = 0

3rd Harmonic:
We have A = 9, f = 3000 and φ = 0

5th Harmonic:
We have A = 6, f = 5000 and φ = 0

7th Harmonic:
We have A = 2, f = 7000 and φ = 0

Note: The even-numbered harmonics have 0 amplitude that is why they are not shown here.
