Answer:
m = 5.27e18 kg
Explanation:
The pressure of a fluid is the weigth of a column of that fluid over base of that column.
The weight of the column is its mass multiplied by the acceleration of gravity. The acceleration of gravity varies with height, however the variation is small and can be ignored, consifering the acceleration of gravity constant.
So:
If we consider the entirety of the atmosphere as a single column the base would be the surface of Earth. Approximating Earth as a sphere:
Now, we can obtain the mass of the atmosphere:
Option B would be the right one
The answer is B !!!!!!!!! It’s B electrical
<h3><u>Given</u><u>:</u><u>-</u></h3>
Force,F = 10,000 N
Acceleration,a = 27 m/s²
<h3><u>To</u><u> </u><u>be</u><u> </u><u>calculated:-</u><u> </u></h3>
Calculate the mass.
<h3><u>Solution:-</u><u> </u></h3>
As We know that,
★ Putting the values in the above formula,we get:
Applying the concept of scalar product. We know that vectors must be multiplied in their respective corresponding component and then add the magnitude of said multiplications. That is, those corresponding to the component are multiplied with each other, then those corresponding to the component and so on. Finally said product is added.
The scalar product between the two vectors would be:
Therefore the scalar product between this two vectors is 5.74
