Answer:
Real images are obtained using a converging lens or a concave mirror. The size of the real image depends upon the placement of the object. A virtual image is an upright image that is achieved where the rays seem to diverge. A virtual image is produced with the help of a diverging lens or a convex mirror.
Here two vectors are given of lengths
now let say the two vectors are inclined at some angle with each other
so the resultant is given as
now plug in all values
Now for maximum resultant the angle between two vectors must be ZERO degree
Now for minimum resultant the angle between two vectors must be 180 degree
Answer:
Basically, it is because through probing the extreme environments of faraway massive galaxies, we can learn not only about their evolution and the history of the universe, but most importantly about the fundamental processes regulating the formation of stars.
