Answer:
1 solar masses
Explanation:
-Sirius has to maintain equilibrium with it's companion.
-Let x be the mass of Sirius and y be the mass of it's companion.
-From the question, we know that Sirius is 2.35 times heavier than it's companion:
Hence, the mass of it's companion is 1 solar masses
1st ionizaton energy has a trend from down to up and from left to right. Since Na and Al are on the same period (row), then the we look at which is the the furthest to the right and that would be Al.
THe answer will be C
because if you put somethin ht next to something cold it will become cooler and if you be two things that are hot next to each other they will remain hot.
Answer:
Two possibities: Increase in pressure or decrease in temperature.
Explanation:
