Answer:
Explanation:
Kinetic energy of a gas molecule = 3/2 k T
1/2 m v² = 3/2 k T
v² ∝ T
(v₁ / v₂)² = T₁ / T₂
( 180 / 48.4 )² = 270 / T₂
13.83 = 270 / T₂
T₂ = 19.52 K .
Exit temp = 19.52 K .
The answer would be C. 80%
Put 160 over 200 and find the GCF
160/200÷40=4/5=80%
The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.
Galileo only saw the system through a scope
Poder = (resistencia) x (corrente)²
Poder = (10 ohms) x (5 A)²
<em>Poder = 250 watts </em>(250 Joule por segundo)
2 horas = 7,200 segundos
Energia = (250 joule/seg) x (7,200 seg)
<em>Energia = 1,800,000 Joules</em>
