The same amplitude and wavelength traveling in the same direction
Longitudinal
The difference between the two speeds. So if one car is traveling at 60mph and the other is 70mph, it would be a 10mph difference since they are traveling in the same direction. Now, if they were colliding head on, it would be 130mph total speed.Also, 2 cars traveling at exactly the same speed and direction (assuming they start a certain distance apart) will never collide and will maintain that exact distance they started apart.
It's called a longitudinal wave.
It is travelling at a constant speed. This does not mean that there is no acceleration or that the direction of motion remains the same.

The Space Station is traveling East -- the same direction the Earth rotates.
There is no smoke. It's an electric train
Yes, you should stop.
yes
The same amplitude and wavelength traveling in the same direction
all waves traveling in the same direction.
Yes. The belt goes over both cams at the same time traveling in the same direction.
Slow down until you can safely follow the equipment (if it's traveling the same direction you are), then carefully wait till there is a clear opportunity to safely pass. If the equipment is traveling in the opposite direction, slow down until you can be sure how much clearance space you may need to allow it to get by you. The main thing to remember is --SLOW DOWN !!!
Yes. If they are traveling in the same direction and at the same speed, then they have the same velocity.
