How does a ground wire let electrons get to the ground?
The ground wire (equipment grounding conductor) runs back to the panel then to a ground rod. If there is a ground fault in the circuit, the current will flow on the equipment grounding conductor back to ground. Electricity follows the path of least resistance. This is why a ground wire is so important and why NOTHING should ever be hooked to a ground wire. It has the least resistance back to source.
What chemical property of helium makes it a better choice than hydrogen for use in airships?
It's very light (only hydrogen gas is less dense than helium), it's relatively cheap, and (most importantly) it's not flammable (hydrogen gas is--the Hindenburg was filled with hydrogen gas).
What triggers a super nova?
When its original source of fuel has run out for instance our sun runs on hydrogen, after the depletion of the original fuel is gone the suns core condenses creating helium were the star expands to great measures were it gets to a size were its limited supply of helium runs out either collapsing into a black hole or a dwarf star
What do you call a star out of gas?
Technically, they never run out of gas. A process called fusion combines huge amounts of hydrogen to make helium. When all of the hydrogen runs out, fusion takes place on the helium and the star rapidly increases in size.
When a red gaint complets helium fusion and collapses it becomes?
When a star runs out of helium, it may still fuse helium into heavier elements - it need not collapse immediately. Eventually, however, the star will run out of usable fuel, and collapse. In that case, depending on its remaining mass, it will become a white dwarf, a neutron star, or a black hole.
What will happen when you release a balloon filled with helium in the air?
it will keep going up and the wind will take it somewhere very far away and when the helium runs out it comes down
How high can a helium balloon go?
High enough, until it gets popped. So it can fly up forever. Unless, of course a bird flies into it, popping and sending it back to Earth. It will fly as high as it can until it runs out of air, or if it runs into a power line because when it runs into a power line, the current electricity will cause it to pop. There are also different reasons why the balloon will pop. The higher the balloon goes, the lower the atmospheric pressure will be, so the balloon will expand as if helium were being added. When it expands far enough, it will pop.

What makes an air balloon rise?
it runs on propane.
When a star runs out if hydrogen what does it use as fuel source?
helium
What is the importance of the burner in a hot air balloon?
If the burner fails or runs out of fuel, the hot air in the balloon (that gives it lift) would cool and the balloon would come down to earth.
Where do rainwater run back into?
The rain water runs to the ground from which the water evaporates into the atmosphere in the form of vapour.&then by the process of condensation the watervapour becomes cloud&its fall on the ground.in this way the rain water circulates ground to air&air to ground.
What happens if the heat source for a hot air balloon runs out?
It falls out of the sky and you die

How do you get a diagram of 6.0 diesel engine?
What is the proper name for the braided cable that runs between the fire wall and the back of the engine where the head is located on a 6.0 diesel It is a ground strap. it provides a ground between the engine and the body.
Bird that runs on the ground?
An ostrich runs on the ground instead of flying. Some ostriches can run as fast as 70 miles per hour.
What changing mass is the sun's supply of energy?
It converts Hydrogen to Helium by nuclear Fusion, eventually when hydrogen runs out it will convert helium to a heavier element and so on till it burns out and dies
