Answer:
<em>The pressure given by the water at the bottom is 58,800 Pa</em>
Explanation:
<u>Pressure Exerted by a Column of Liquid
</u>
The pressure P exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation:
P = ρgh
Where ρ is the density of the liquid, g is the acceleration of gravity g=9.8m/s^2, and h is the height of the column of liquid.
The height of water in a well is h=6 m. The density of water is a known quantity:
Calculating P:
P = 1,000*9.8*6
P = 58,800 Pa
The pressure given by the water at the bottom is 58,800 Pa

They study things like the big bang thery and studied mainly by nasa.
Have a nice day
Resistance = (voltage) / (current) . . . <== MEMORIZE THIS
Resistance = (91 volts) / (10 Amperes)
Resistance = 9.1 ohms
Answer:
maximum height = 31.63 m
Explanation:
Please notice that the units of velocity that you were giving are incorrect. They should be m/s. The ones given in the problem are in fact units of acceleration (not velocity). I am assuming that the initial velocity of the rock is 24.9 m/s to solve this problem.
Let's start by finding the time it takes the rock to reach that maximum height at which point, the velocity of the rock will be zero (just before changing its direction of movement and starting heading down.
We can use the fact that the initial velocity () of the rock is 24.9 m/s, the final velocity () at the maximum height is zero, and that the only acceleration it is getting is that of gravity (g) slowing down it motion:
Now we can use this time it takes the rock to reach the maximum height, in the kinematic expression for the distance covered:
The units of height will come directly in meters (m) after evaluating, since we use all the quantities in the SI system.
