If a hole were drilled from one side of the Earth straight through the other side would a thousand-pound steel ball go right through if it were thrown into the hole disregarding the heat and pressure?
Nichiyoubi
It would fall through nearly to the other side, but due to friction (air resistance) it would not make it all the way through. It would then reverse direction, and return nearly to the starting point, then repeat this cycle many many times, each time decreasing in amplitude, until the oscillations finally came to an end and it would remain floating at the center of the earth. Basically, the same effect as a giant linear pendulum.

How did the anicent egyptians cure a toothache?

When spraying into holes drilled for termite control how many psi pressure is needed for spraying device?
36 psi
Have we drilled into the upper mantle?
no. project mohole in the 1950s tried but could not do it. the rock is too hot and the pressure too high for drilling equipment.
What do you call oil that is first drilled?
Second-drilled oil.
Why does water in an artesian well?
Basically due to pressure - In an artesian well, the aquifer (water bearing rock) is sandwiched between a top and bottom layer of impermeable rock that creates pressure. When it's drilled the pressure is relieved and the water finds a route to air.
Are starter bolt pattern straight across or staggeredon 350 crate motror from advance auto?
It depends on the year of the block, but most are drilled for both bolt patterns.
What A drilled water well that allows water to rise to the surface without using a pump?
A well that allows water to rise without a pump is an artesian well. This is usually a very narrow well drilled into strata capable of pushing water to the surface by internal hydrostatic pressure.

To relieve pressure or pain in a person's head even ancient cultures drilled holes in the skull a practice called?
Trephining - ("truh-FINE-ing")the relieving of pressure or pain in a person's head by drilling holes in the skull.
After a natural gas well is drilled why is there a flame that comes out of the well?
After a natural gas well is drilled there will be a flame that comes out of the well for a while. This is so the pressure and flow of the gas can be tested. It is called gas flaring. It also burns off excess gas that might not be captured when they are collecting the gas.
In which state was the first oil in the US drilled?
It was drilled in Pennsylvania by a man named Edwin Drake and he drilled the well in 1859 near titusville. By: Raysean Potts
