D. The block should move to the left.
Since the forces are in opposite directions the difference of these forces determines the magnitude and direction of the block. Therefore,
20 N left - 10 N right = 10 N left
Answer:
The pressure is 
Explanation:
From the question we are told that
The depth of the swimming pool is 
The density of water is 
Generally the total pressure exerted on the bottom of the swimming pool is mathematically represented as
Here 
is the atmospheric pressure with value
So
![P = 101325 + [1000 * 9.8 * 3]](https://tex.z-dn.net/?f=P%20%3D%20101325%20%2B%20%5B1000%20%2A%209.8%20%2A%203%5D)

When using parallax, astronomers calculate distance from the sun and not earth to improve on the accuracy of their measurement, since parallax angle decreases as star distance increases.
<h3>
What is parallax distance?</h3>
Parallax enables astronomers to measure the distances of far away stars by using trigonometry.
<h3>Why does astronomers measure parallax distance from sun?</h3>
As the distance of star increases, the parallax angle decreases, and great degree of accuracy is required for its measurement.
So taking a refence from the earth instead of the sun will impact the accuracy of their measurement.
Thus, when using parallax, astronomers calculate distance from the sun and not earth to improve on the accuracy of their measurement, since parallax angle decreases as star distance increases.
