You left off a pretty critical "f" in one of your words. Be careful.
I'd have to see the diagram. And also 0.40 what? You need units.
The train's acceleration cannot be determined from the information provided.
When two objects are moving with respect to each other at different speeds, and that difference is a good fraction of the speed of light, then the rate of time passing on one object would seem to an observer on the other object to be different.
You can't take liquid jels or shampoos, lotions or any kind of cosmetics. No firearms. If you have any sharp objects they need to be wrapped safely. The gel that people put in there shoe is to be scanned before passing security.
yes it is because it is a C. 70 and up is passing so congrats for passing
60% is not normally a passing grade in college.
yes
All objects have the potential to make sound when passing through or striking a medium.

a vel time graph passing through d origin.... at t=0.. vel=o.. bt acceleration not=0..
The noise can be comming from the weather stripping around the door, the wind passing past the antenna or from the wind around the luggage rack on acceleration.
Mach speed has nothing to do with passing out. A pilot might pass out from high acceleration, but this has nothing to do with speed.
Gravitational lensing.
No, but without it you'll need to manually shift it up and down for passing or other quick acceleration situations.
The train's acceleration cannot be determined from the information provided.
What a Switch DoesA switch starts or stops current from passing through in order to turn electrical objects on and off.
No. Photons have no rest mass and therefore can never accelerate or decelerate; they always travel at precisely the speed of light in the medium they're passing through.
This sounds like you mean insulators. There's no material which is a perfect thermal insulator.
