The angular size of a black hole varies proportionately with its mass.
a) use your computed mass (from p3c above) to compare the angular linear sizes, in au, of the 6.5 billion m⊙ black hole in m87 and sgr a*.
b) which object subtends the greater apparent size and would therefore be easier to study?
c) what other factors complicate the study of sgr a*?

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
