Shallow (small, low).
If there werent any plants, then there would still be air, but not that much oxygen, which is necessary for animals.
yes. an invasion of japan would have costed about 1 million american/allied lives.
So that experiments can be reproduced. And not just science ... How about shopping for a pound of meat, or building anything ... whose foot would you use as a standard.
A proof of principle experiment is one designed to see if the idea is workable. Usually little if any data is collected. Example: " I wonder what happens if I push this button?" Better example: " Can energy be generated by wind?" To do a proof of principle experiment, it would only be necessary to generate "some" energy from "some" wind by "some" method. It would not be necessary to collect data or decide the practicality of a particular method.
A manometer is a device that measures fluid pressure. A hypsometer is an instrument that measures height or elevation. One way to measure elevation is by using atmospheric pressure, which decreases with altitude. A hypsometer that uses this principle is called a boiling point apparatus or a pressure hypsometer. It consists of a thermometer and a vessel in which water is boiled. The boiling point of water depends on the atmospheric pressure, so by measuring the temperature of the boiling water, the pressure can be inferred and then converted to elevation. A manometer can be attached to the hypsometer to measure the pressure of the steam inside the vessel directly, without relying on the thermometer. This can improve the accuracy and reliability of the elevation measurement, especially if the thermometer is not calibrated or affected by other factors. A manometer with only one side open to the atmosphere is an ideal device for measuring gauge pressures, which are relative to the atmospheric pressure. The gauge pressure is p g = hρg and is found by measuring h, the height difference of the fluid columns in the U-shaped tube of the manometer. By knowing the gauge pressure and the atmospheric pressure, the absolute pressure inside the vessel can be calculated and then used to determine the elevation.
To use an inclined water manometer for air conditioning, you would first connect one end of the manometer tube to the air conditioning system at a pressure measurement point. Then, you would position the manometer at an incline to measure the pressure difference between the two ends of the tube. This pressure difference can help determine if the system is operating within the desired pressure range.

A pressure gauge or manometer is typically used to measure pressure above atmospheric pressure. These devices can accurately measure the pressure difference between the system being measured and atmospheric pressure.
According to Bernoulli's principle, the sum of static, velocity and kinetic heads at two points in a fluid flow should be equal, assuming steady state. A manometer measures static head through the height of fluid at two points. Hence, it would be apt to say that manometer is an application of hydrostatic measurement.
Determine how tall a building, flagpole, street light or basketball goal is. They need to understand basic trig, and angle of elevation/depression. They would need to make a clinometer or hypsometer.

The U-tube in an inverted differential manometer is inverted because it allows the device to measure pressure differences accurately. When one side of the U-tube is connected to a system with higher pressure than the other side, the liquid in the U-tube moves to create a visible difference that can be measured. If the U-tube were not inverted, the liquid would not move, and accurate pressure readings could not be obtained.
The pressure measured in a closed two-liter container would depend on factors such as the temperature and the amount of gas or liquid inside the container. If the container is sealed and there is no chemical reaction occurring inside, the pressure would remain constant at the equilibrium pressure of the system.
A manometer can be used to measure the level of a fluid by connecting one end of the manometer tube to the container holding the fluid. The difference in height between the fluid levels in the container and the manometer tube indicates the pressure exerted by the fluid, allowing you to determine the level. Make sure the manometer is calibrated and positioned correctly for accurate measurements.
