Answer:
P_(pump) = 98,000 Pa
Explanation:
We are given;
h2 = 30m
h1 = 20m
Density; ρ = 1000 kg/m³
First of all, we know that the sum of the pressures in the tank and the pump is equal to that of the Nozzle,
Thus, it can be expressed as;
P_(tank)+ P_(pump) = P_(nozzle)
Now, the pressure would be given by;
P = ρgh
So,
ρgh_1 + P_(pump) = ρgh_2
Thus,
P_(pump) = ρg(h_2 - h_1)
Plugging in the relevant values to obtain;
P_(pump) = 1000•9.8(30 - 20)
P_(pump) = 98,000 Pa
Answer:
Volcanoes that form away from plate boundaries are created by hotspots. A hotspot is an area in the mantle that is believed to be somewhat hotter than the surrounding material. The rising magma from the hotspot can push its way through the crust and burst out at the surface, forming a volcano.
Explanation:
The bear is white in color because it is a polar bear.
<h3>What are the color of bears?</h3>
Bears are very large carnivorous animals found around the cold regions of the Arctic or North Pole.
The color of bears, may be brown, black or white depending on how far North the bears are found.
Bears found close to the Arctic or North pole are white polar bears.
Based on the description of the house, every side of the home faces South meaning that the individual lives in the North pole.
Therefore, the color of the bear will be white.
in conclusion, polar bears are white in color.
