To solve the problem it is necessary to apply the definition of Newton's second Law and the definition of density.
Density means the relationship between volume and mass:
While Newton's second law expresses that force is given by
F = ma
Where,
m = mass
a= acceleration (gravity at this case)
In the case of the given data we have to,
In equilibrium, the entire system is equal to zero, therefore
Where,
Weight of balloon
Weight of helium gas
Bouyant force
Then we have,
Replacing the values we have that
Now by ideal gas law we have that
But the relation \frac{n}{m} is equal to the inverse of molar mass, that is
Therefore the pressure of the helium gas assuming it is ideal is 0.61Mpa
Answer:
6 m/s
Explanation:
Well we can find acceleration a=v/t = (21-0)/7=3 m/s^2
vf=at+v0, use this equation to solve for the vf
vf=3(2)+0=6 m/s was its speed at 2s
Answer:
At point A. it gets kinda loud then at point B. it gets very loud than at point C. it gets quieter than at point D. it gets more silent.
Explanation:
Because you can tell when the waves get large it gets louder and then when the waves get more far apart then it get more quiet. Hope this helped!
Obesity is primarily caused by a lack of physical activity or by unhealthy dietary habits. The positive energy balance underlying obesity is generally attributed to chronic excess energy intake or reduced physical activity.
