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.
yes it is because it is a C. 70 and up is passing so congrats for passing
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.
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.
60% is not normally a passing grade in college.
yes
The force that counteracts a contact force to prevent objects from passing through surfaces is called the normal force.
Objects that do not transmit light are called opaque objects. These objects absorb or reflect light, preventing it from passing through them. Examples include wood, metal, and concrete.
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.
Those objects are called opaque objects. They prevent light from passing through them, creating shadows when they block light from a source.
Observing the scenery passing by outside the train window. Feeling the sensation of acceleration or deceleration when the train starts or stops. Noticing the movement of objects inside the train in relation to oneself.
Gravitational lensing.
All objects have the potential to make sound when passing through or striking a medium.
Transparent objects do not block light entirely, so they do not cast shadows as opaque objects do. They may create soft or colored shadows depending on how they refract and scatter light passing through them.
No, but without it you'll need to manually shift it up and down for passing or other quick acceleration situations.
