A physics student drinks her coffee out of an aluminium cup. The empty cup has a mass of 120g
at 20.0°C. Assuming she pours in 300g of coffee at
70°C, what is the final temperature after the coffee
and the cup must have attained thermal
equilibrium? (Assume coffee has the same specific
heat capacity as water and that there is no heat
exchange with the surrounding).​

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.

Gotta have a picture ^^
