Answer:
According to the General Theory of Relativity, a black hole is a region of space from which nothing, not even particles that move at the speed of light, can escape because their velocity is less than the escape velocity of these infinitely dense celestial bodies . This is the result of the deformation of space-time, caused after the gravitational collapse of a massive star with at least 30 times the mass of the Sun in a supernova, and that soon after, will disappear, giving place to what Physics calls singularity, the heart of a black hole, where space-time ceases to exist. A black hole starts from a spherical surface called the event horizon, which marks the region from which, if something to cross, can not return. The black adjective in black hole is due to the fact that it was assumed that it did not reflect any part of the light that reaches its horizon of events, acting as if it were a perfect black body in thermodynamics, however, there is currently the theory of radiation Hawking, who briefly predicts that black holes are not really black, and emit radiation due to quantum effects such as quantum fluctuations.

Answer:
a. The lives of medieval women were more limited than those of men.
The tactics that civil rights activists used to oppose racial segregation were sit- ins, boycotts and protest marches.
Explanation:
The Civil Rights Movement was a social movement undertaken by the colored people, to end the racial discrimination against them.
People of many different races and religions were also part of the movement.
But predominantly, most of their activists were African- Americans. Activists no matter what their race or religion was, joined in the protest.
The participants led a very non- violent form of protest. Despite the fact that they were attacked by angry mobs, they refused to bow down to the violence and carried on with their protest quietly.
Finally, the outcome was in the favor of the African Americans, and the white people slowly changed their attitude towards the colored race and gave them the rights, they deserved.
