What do mechanical waves need to travel?
Matter! Watching a wave travel through water is mechanical waves. Putting your ear to train tracks, and hearing the train, and feeling the vibration is a mechanical wave. Same with hearing someone talk!

Why do you think that the steel sky scraper has no need for lightning rods?
The entire structure acts like a lightning rod- it connects the negative charges in the clouds to the positive charges in the ground. Normal houses especially need lightning rods because the there isn't much metal (or steel in this example) that can conduct the induced current like a steel skyscraper has the ability to.

Buses stop at railroad tracks to ensure that trains are not close by. Buses are longer than cars and therefore need more time to get across the tracks.
What do I need to know about rubber tracks?
Rubber tracks allow machinary to travel at higher speeds than steel tracks, they do less ground damage, they are quieter, you get superior traction and your overall machinery weight is lighter which uses less energy to run.
What will happen to steel railroad tracks on a hot day if they were laid out during a cold day without clearance or gap?
When metals become cold, they contract and take less space, but when a metal gets hot, it expands and it will need more space. So, in this case the metal tracks took less space when fitted without gaps on the cold day, but on the hot day the metals will need more space and therefore will push outwards. The tracks will become buckled, and when the train comes, it will go off track.
How can you compare a circulatory system with a train system?
The train tracks would be like the blood vessels with An actual train being like the fluid in the blood. each train car of a train would represent a different cell or chemicals examples would be like red blood cells would have multiple train cars for them. Inside there would be O2 , if it were on a artery "track", or CO2, if they were on a vein "track". Capillaries represent stations which exchanges O2 and CO2. The heart represents a hub of train tracks which lead the different "Trains" to where they need to go.

What does the flagman on a train do?
I believe that they flag the trains to warn them of work being done on the tracks or signals being worked on. Tracks need to be constantly inspected so I believe that they must use flagmen in order to keep the flow moving while still being able to inspect properly

Who has examples of irregular phrase adjective or noun jokes This was an old group of jokes I do not recall who started them like He is a moron You need more sleep I need to rethink that?
Believe it or not, I know what you're talking about: Two morons were walking through the woods and they came to some tracks. The first moron said "These look like deer tracks," The other moron said, "No, they look like moose tracks." They argued and argued, and they were still arguing when the train hit them.
