I think this answer is False because i believe the right lane is the slowest lane you could be in.
Sunlight focuses at a point 18.5 cm behind the lens. As daylight comes from an indefinite distance, so it is a real image. The lenses that will focus on the parallel rays behind the lens are converging lenses.
What is a converging lens?
- A converging lens causes parallel rays of light to come to a focal point.
- A convex lens is a converging lens.
- A converging lens has a positive focal length.
- A converging lens forms a real or virtual image of a real object.

Answer:
If you add the 2 velocity vectors you get the velocity of the third vector which is the (change in) velocity of the cue ball after striking the cushion
V * 2 * cos 45 = 4 * cos 45 = 2.83 m/s
"physical science" is a branch of science that is based on practical tests and explanations of the different phenomena. It is based on scientific evidence and tests/experiments.
Some of the branches that are based on physical science are:
1- Astronomy
2- Electronics
3- Engineering
