Answer:
The velocity at the nozzle at inlet 
= 3584 
Explanation:
Pressure at inlet 
= 1 × 
Pa
Temperature at inlet 
= 518 ° c = 791 K
Mass flow rate = 
= 88.7
Gas constant for carbon die oxide is R = 189 
Mass flow rate inside the nozzle is given by the formula = 
× 
×
⇒ = = 1 × Pa
⇒ R = 791 × 189 = 149499 
⇒ = 0.0037 
Put all the above values in above formula we get,
⇒ 88.7 = 
× 0.0037 ×
⇒ = 3584
This is the velocity at the nozzle at inlet.
To determine the energy equivalent of an object, we use the famous equation of Einstein which is E=mc^2 where m is the mass of the object and c is the speed of light (3x10^8 m/s). We calculate as follows:
E = mc^2
E = 1.83 kg (3x10^8 m/s)^2
E = 1.647x10^17 J
Answer:
1.414
Explanation:
Snell's law states:
n₁ sin θ₁ = n₂ sin θ₂
where n is the index of refraction and θ is the angle of incidence (relative to the normal).
The index of refraction of air is approximately 1. So:
1 sin 45° = n sin 30°
n = sin 45° / sin 30°
n = 1.414
Round as needed.
Rational expectations theory suggests that the speed of adjustment Purcell correction would be very quick.
<h3>What Is Rational Expectations Theory?</h3>
The rational expectations theory is a widely used concept and modeling technique in macroeconomics. Individuals make decisions based on three primary factors, according to the theory: their human rationality, the information available to them, and their past experiences.
The rational expectations hypothesis was originally suggested by John (Jack) Muth 1 (1961) to explain how the outcome of a given economic phenomena depends to a certain degree on what agents expect to happen.
- People who have rational expectations always learn from their mistakes.
- Forecasts are unbiased, and people make decisions based on all available information and economic theories.
- People understand how the economy works and how government policies affect macroeconomic variables like the price level, unemployment rate, and aggregate output.
