Two observers travel perpendicular to each other,as shown in the figure below.If observer B shone a light toward observer A,what velocity would observer A measure the beam to have?

An astronaut falls into a black hole that has 100 times the mass of the Sun.The astronaut sends signals to her partner,who sits at rest a large distance from the black hole.How far from the black hole's center is the astronaut when her signals can no longer reach her partner?

Suppose a supermassive black hole moves across the line of sight to a distant star,as shown in the figure below.How will the star appear to change to an observer on Earth?
