Uhh? Do you have any questions or need help?
Answer:
V2 = 4.5 dm³
Explanation:
Dados los siguientes datos;
Volumen inicial = 3 dm³
Temperatura inicial = 20°C Temperatura final = 30°C
Para encontrar el nuevo volumen V2, usaríamos la ley de Charles.
Charles afirma que cuando la presión de un gas ideal se mantiene constante, el volumen del gas es directamente proporcional a la temperatura absoluta del gas.
Matemáticamente, Charles está dado por;
Dónde;
V1 y V2 representan los volúmenes inicial y final respectivamente.
T1 y T2 representan las temperaturas inicial y final, respectivamente.
Haciendo V2 como la fórmula del sujeto, tenemos;
V2 = 4.5 dm³
Answer:
d = 2021.6 km
Explanation:
We can solve this distance exercise with vectors, the easiest method s to find the components of the position of each plane and then use the Pythagorean theorem to find distance between them
Airplane 1
Height y₁ = 800m
Angle θ = 25°
cos 25 = x / r
sin 25 = z / r
x₁ = r cos 20
z₁ = r sin 25
x₁ = 18 103 cos 25 = 16,314 103 m
= 16314 m
z₁ = 18 103 sin 25 = 7,607 103 m= 7607 m
2 plane
Height y₂ = 1100 m
Angle θ = 20°
x₂ = 20 103 cos 25 = 18.126 103 m = 18126 m
z₂ = 20 103 without 25 = 8.452 103 m = 8452 m
The distance between the planes using the Pythagorean Theorem is
d² = (x₂-x₁)² + (y₂-y₁)² + (z₂-z₁)²2
Let's calculate
d² = (18126-16314)² + (1100-800)² + (8452-7607)²
d² = 3,283 106 +9 104 + 7,140 105
d² = (328.3 + 9 + 71.40) 10⁴
d = √(408.7 10⁴)
d = 20,216 10² m
d = 2021.6 km
