Answer:
Quasars inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars.
Explanation:
sorry if im wrong
The answer would be triple point! Easy to remember because triple as in 3 :)
Answer:
A, is a girl balancing on her hands, a red arrow is pointing up and is the same length as an arrow pointing down.
Explanation:
vvEven she was still on her feet the force thats pulling her down is gravity and when you have figure the force that makes it easier so when the 2 arrows are the same size that means the force is balenced
please brailiest please i need one more
Answer: 
of liquid sodium is required.
Explanation: To calculate the mass of liquid sodium, we use the formula:
where,
q = heat required, 
(Conversion factor: 1MJ = 1000000J)
m = Mass of liquid sodium, 
M = Molar mass of liquid sodium, 
c = Specific heat capacity, 
= change in temperature, 
(Conversion factor: 0°C = 273K)
Putting values in above equation, we get:
To figure this out, you need to figure out how many molecules of mgso4 you have.
If you have 1.04 moles of MgSO4, you have that many moles times avogadro's number (6.022*10^23 molecules/mole).
1.04 moles MgSO4 * (6.022*10^23 molecules MgSO4)/1 mole MgSO4 =
6.263 *10^23 molecules MgSO4
Next, there are 4 oxygen atoms per molecule of MgSO4, so we multiply the number of molecules of MgSO4 by 4 to get the number of oxygen atoms.
6.263 *10^23 molecules MgSO4 * (4 oxygen atoms/1 MgSO4 molecule) = 2.51 * 10^24 oxygen atoms in 1.04 moles of MgSO4
