Petroleum engineers are the people in charge of getting the oil from the ground and into storage tanks in the safest way possible, here is more information: http://careers.stateuniversity.com/pages/75/Petroleum-Engineer.html
The space wave is the wave that propagates directly through free space, rather than via some other object or medium like the ground.
Typically digital circuits will pump a lot of fast transient currents into the ground. Since real grounds have resistance and inductance, this will produce a drop between the ground of the digital circuits and the power supply ground. This is the so called "ground bounce". If an analog circuit ground shares ground path between the digital ground and the power supply ground, it will see this voltage drop. Depending on the common mode rejection of the analog circuit in question and the frequency components in the "ground bounce" this may or my not be an issue. If it's an issue, the easy solution is to connect the analog ground directly to the power supply ground without sharing any of the path from digital ground to main power supply ground. This way the current spike induced drops in the digital ground don't show up in the analog ground. A good example would be ADC grounding for the digital and analog portions of the ADC chip.
Voltage on ground can mean an open ground. It can also mean (high) current on ground, due to a ground fault such as reversed neutral and ground.
The footing lies on the ground around the base of the structure. The Foundation cn go way below with pilings deep into the ground.I can say that the footing is the part of foundation which transfers the load directly to the soil and foundationis the part of structure below the plinth level including the footing while footing is the part which is below the ground level.
The likelihood of a Navy SEAL ground solider to be captured varies with the circumstances of a given mission.
Petroleum is recovered from the ground by drilling deeply into the ground. There are also many other Fossil Fuels, if you would like to look them up. They are all taken from the ground.
Petroleum safety is the absence of injury or illness when using or exposed to petroleum or during its extraction from the ground.
it is pumped from the ground BY; ZxLILJOCxZ
Petroleum
coal, petroleum
It is taken from the ground by pumps sucking it out
"Petroleum" products are distilled from crude oil, so what comes out of the ground is crude oil.
Petroleum and coal.
they both are made from the ground
petroleum is usually taken form the ground by drilling a narrow hole into a petroleum deposit and simply pumping out the oil
