<h2>Answer:</h2>

Accretion of material due to supermassive black holes in galactic cores leads to intense active galaxies luminosity.

<h2>Explanation:</h2>

The center of the galaxies has a high luminosity as compared to other parts postulated to be emitted by something other than the stars because of its intense luminosity. They are electromagnetic radiation source which is useful for discovering objects from outer space.

They can be observed by gamma rays, ultra-violet, radio, microwave, x-rays, infrared, and many more similar. Classification of an active galactic nucleus which is based on their observed characteristics has been made and the quasar is the powerful one.

How did Israel respond to the PLO’s use of terrorist tactics during the 1970s? by granting Palestinians limited self-government

maxonik [38]

Israel responded by what is termed here 'terrorist' tactics of the PLO in the 1970's by raiding PLO bases in neighboring Arab countries. It must be realized historically that Palestine used to belong to the Arab Palestinians ie it was their country and it was stolen by the British colonialists and sold to the rich Zionists for their so-called homeland. If the Israel govt really wanted to live in peace with the Palestinians and be slightly modest that they took away their country, then they wouldn't provoke them with settlements in the little land left that the Palestinians have on the Westbank and they would live in peace and harmony with them and Israel could have both Arabs and Jews living in harmony.

If she earns $10.65 and she worked 38 hours last week, I believe you would just multiply the two to get $404.70.
