Railway signal
yes
A car is stopped at a traffic light because the light is red, indicating that it is not safe to proceed through the intersection.
Car B would be at fault do to the fact that they failed to yield at a traffic light.
when the car stops at the traffic lights and the train stops at the station.
acceleration, I think
When a car slows down at a traffic light, it is decelerating. This means that the car is reducing its speed or coming to a stop in response to the signal.
If you are asking about a traffic light then it was invented to prevent car accidents.
Rather, a car stoppping at a light is an example of deceleration but one of the possible example of acceleration when a car stops at a traffic light is a pedestrian accelerating across the road or other car in different lanes accelerating to move to on in their journey.
A "Green Wave" is a sensor on the traffic lights that allows the main flow of traffic to continue to have a green light unless another car is to pull up in the other direction then the light would change to let the other car go.
i do not have a clue what your talking about! why not define what you mean?
Depends if your taking the train 10 minutes, but by car its probably about 20 minutes- half an hour because of traffic and such
In a car a trip to London from Cornwall is about 5-6 hours. Unless you get stuck in traffic. If you are travelling on a coach it takes longer because they have speed limits. Then it is about 6-7 hours. Again, it can be more if there is lots of traffic. A train journey takes the same as a car. As you can guess, there is no traffic jams when travelling by train. On a plane it is only about an 1 hour I think.
