Question

1) Active galaxies are thought to be powered by

dark matter

a giant pulsar

a central, supermassive black hole

friction from condensing gases

2) Imagine that two new planets have been discovered. Planet A has an orbit that lies between Mercury and Venus. Planet B has an orbit that lies between Jupiter and Saturn. Describe and compare at least 3 general properties each planet is likely to have.

3) Describe how energy gets from the core of the sun to Earth.

Answer 1

What they said^

Answer 2

1)a central supermassive blackhole,and what type of active galaxy it is simply depends on the angle that its viewed!

planet A between mercury and venus should be rocky,,hot andhas a rotation around the sun that is relativly quik

planet Bshould be a gas giant,cold and massive

it takes millions of years to reach the surface from the core,but once it does its a 8 min trip!!!

Answer 3

1 - suppermassive black hole

2 - 1)cannot support life

      2)spherical shape

      3)regular rotation(nonretrograde)

3 - the Sun's radiation zone carries energy from the core about i think 83 percent of the distance from the core to the surface, then convection currents carry it to the surface. Solar winds then carry it off at very high speeds outwards where it will reach earth in 8 minutes.
