Explanation:
Según el modelo cinético, las moléculas de gas están en constante movimiento.
La energía cinética promedio de las moléculas del gas depende de la temperatura del gas y de la masa molar del gas.
Si los dos gases ocupan el mismo volumen a la misma temperatura, la energía cinética promedio ahora depende de la masa molar de los gases individuales. Cuanto menor sea la masa molar del gas, mayor será la velocidad media de las moléculas del gas.
El oxígeno gaseoso tiene una masa molar menor que el dióxido de carbono. Por lo tanto, el oxígeno tiene una velocidad molecular promedio mayor que el dióxido de carbono.
Answer:
The part of the Sun that you are observing is the photosphere . This appearance is called photosphere.
Explanation:
Answer:
F = W + ma a> 0
Explanation:
For this exercise let's use Newton's second law
we assume the upward direction as positive
F - W = m a
F = W + ma
F = m (g + a)
In this case they indicate that the speed is less and less as it goes down, therefore the acceleration must be opposite to the speed, that is, the acceleration is upwards, consequently it is positive
We can see that since a> 0 the force F must have greater than the weight of the elevator
Answer:
The height of the bridge is 78.4 m.
Explanation:
Given;
time of the stone motion off the bridge, t = 4.0 s
acceleration due to gravity, g = 9.8 m/s²
The height of the bridge is given by;
h = ut + ¹/₂gt²
where;
u is the initial velocity of the stone, u = 0
h = ¹/₂gt²
h = ¹/₂(9.8)(4)²
h = 78.4 m
Therefore, the height of the bridge is 78.4 m.
Vectors need direction and magnitude to exist, otherwise, it becomes scalars that do not require direction to be expressed.
eg - Velocity is a vector as it needs direction, but speed is scalar and does not need direction
hope this helps
