The general formula for absolute pressure is:
Where:
= Absolute pressure
= atmospheric pressure
r = density
g =
h = depth
We can use this formula to derive our formula for h:
transpose atmospheric pressure
=
transpose r and g
-
------------------------- = h
rg
Now let us input our given into our new formula:
3.52 x
- 1.01 x
---------------------------------------- = h
1.00 x
x 9.8
Answer:
3.6×10⁶ m
Explanation:
Newton's law of universal gravitation states that the force between two masses is:
F = GMm / r²
where G is the universal constant of gravitation (6.67×10⁻¹¹ m³/kg/s²),
M is the mass of one object
m is the mass of the other object,
and r is the distance between the center of masses of the objects.
The force acting on the meteor is:
∑F = ma
GMm / r² = ma
GM / r² = a
Given M = 6×10²⁴ kg and a = 4 m/s²:
(6.67×10⁻¹¹ m³/kg/s²) (6×10²⁴ kg) / r² = 4 m/s²
r = 10⁷ m
The distance from the meteor to the center of the Earth is 10⁷ m. We want to know what the height of the meteor is (distance to the surface of the Earth). So we need to subtract the Earth's radius.
h = 10⁷ m − 6.4×10⁶ m
h = 3.6×10⁶ m
Hello!
<span>The air inside the building is easily pressed out the windows because the air is composed of widely spaced molecules in the gas phase.
The word "gas" was created by the Netherlandish scientist Jean Baptista van Helmont from the Latin word "chaos". The gas phase consists of molecules with high kinetic energy, that adopt the shape of the container and tend to expand. The molecules are essentially free, and the gravitational pull on them is negligible.
Have a nice day!</span>
