Answer:
G. It will take twice as long.
Explanation:
Let's call the original speed of the plane and
the distance between Dallas and Pensacola. The time the plane originally takes to complete the flight is
In this problem, we are told that the plane encounters wind moving at half of its speed: , in the opposite direction. This means that the new speed of the plane is
And so, the time the plane takes now to complete the flight is
So, the plane takes twice the time as before.
Answer:
A volume of a cubic meter of water from the surface of the lake has been compressed in 0.004 cubic meters.
Explanation:
The bulk modulus is represented by the following differential equation:
Where:
- Bulk module, measured in pascals.
- Sample volume, measured in cubic meters.
- Local pressure, measured in pascals.
Now, let suppose that bulk remains constant, so that differential equation can be reduced into a first-order linear non-homogeneous differential equation with separable variables:
This resultant expression is solved by definite integration and algebraic handling:
The final volume is predicted by:
If ,
and
, then:
Change in volume due to increasure on pressure is:
