Answer:
Ve = 0.01625 [m³]
Explanation:
This type of problem can be solved by the following expression.
where_
Pi = Initial pressure = 2.5 x 10⁵ [Pa]
Vi = initial volume = 1.5 x 10⁻² [m³]
To = final temperature = 302 [K]
Po = final pressure = 1.2 x 10⁵ [Pa]
Vo = final volume [m³]
Ti = initial temperature = 302 [K]
Now the key to solving this problem is to make it clear that the temperature remains constant throughout the process. That is, it does not change.
But this calculated volume corresponds to the volume of the tank, now by means of the difference between the initial volume and the final volume we can calculate the volume of gas that escaped.
Answer:
A) 58 degree
Explanation:
When unpolarized light passing through first polarizer then the intensity of light becomes half as it will get polarized
So let say the intensity of unpolarized light is "Io" then after passing through first polarizer the intensity will become half
Now when this polarized light passing through another polarizer then the intensity of light is given by Malus law
As per Malus law if the angle between two polarizer axis is inclined at some angle
then it is given as
The gravitational acceleration at any distance r is given by
where G is the gravitational constant, M the Earth's mass and r is the distance measured from the center of the Earth.
The Earth's radius is , so the meteoroid is located at a distance of:
And by substituting this value into the previous formula, we can find the value of g at that altitude:
