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 element does a star run out of that causes them to die?
A star dies when it runs out of fuel to sustain nuclear fusion in its core. This fuel is mainly hydrogen, which gets converted into helium through nuclear fusion. Once the star runs out of hydrogen, it will expand and eventually collapse, leading to its death in a supernova explosion.
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 happens to most of the rain that falls the earth?
Most of the rain that falls on Earth either evaporates back into the atmosphere, infiltrates into the ground to replenish groundwater sources, or runs off into rivers and streams eventually flowing back into oceans. This water cycle helps maintain Earth's ecosystems and sustains life.
What will happen when you release a balloon filled with helium in the air?
When you release a balloon filled with helium into the air, it will rise due to the helium being less dense than the surrounding air. As it ascends higher, the air pressure decreases and the balloon expands. Eventually, the helium will escape from the balloon and it will likely deflate and fall back to the ground.
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.
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.
What energy does a hot air balloon run on?
A hot air balloon runs on the energy stored in the heated air inside the balloon envelope. The heat is usually generated by burning propane gas in a burner located below the opening of the balloon.
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 makes an air balloon rise?
An air balloon rises due to the principle of buoyancy, which occurs when the hot air inside the balloon is lighter than the cooler air outside. This temperature difference creates a pressure difference, causing the balloon to float upwards.
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.
