We will either die cause with no gravity then we cant breathe or we may die due to the fact were in space or maybe be frozen due to the fact we will be 500k feet up air
Answer:
6.18 um
Explanation:
The plumb line will be pulled down by a combination of the gravitationall pull of Earth and of the mountain. The Earth pulls down and the mountain to the side. Because of this it will fall not in a straight line down, but slightly to the side. Since the plumb line will follow the compound gravity we can imagine a rectangle triangle formed by the plumb line, a vertical line that ends at the same height as the plumb line, and the sideways displacement.
The total gravity will be proportional to the plumb line lenght, the vertical line will be proportional to Earth's gravity and the sideways displacement to the mountain pull.
The gravity of Earth is 9.81 m/s^2
The pull of the mountain will be defined by Newton's law of universal gravitation:
Where
F: pull force
G: universal gravitational constant (6.67e-11 m^3/(kg * s)
m1: mass of the mountain
m2: mass of the plumb
r: distance between mountain and plumb (3 km in this case)
If we divide both sides by m2 we obtain the acceleration towards the mountain of the plumb
Now we need the mass of the mountain. This will be its volume times it's density. The volume depends on the radius (since we consider it as a sphere)
So, the acceleration on the plumb will be
This is very small compared to the pull of Earth, so we can make an approximation that the length of the plumb line is equal to vertical line.
We can use the principle of similar triangles to say that:
So:
The sun is the main source of energy
0.050 M Urea, 0.10 M glucose, 0.20 M sucrose and pure water.
<u>Explanation:</u>
Vapor pressure is the measure of pressure existing above the surface of the solution. Depending upon the vapor pressure of solutions, the boiling points will differ. In other words, decrease in vapor pressure leads to increase in the boiling point.
Since, the number of molecules present above the surface of the solution leads to easy evaporation of those molecules. But if the number of molecules on the surface or vapor pressure on the surface will be less, the boiling point will increase.
Thus, 0.050 M urea has the highest vapor pressure indicating that it can be easily evaporated, then 0.10 M of glucose has the vapor pressure followed by 0.20 M sucrose. Finally, the vapor pressure of water is the lowest and it will have the boiling point of 100 degree celsius.
