The table shows the values of two quantities for an astronaut on Earth and Jupiter. Astronaut's Details Earth Jupiter Quantity A 705.6 units 1,868.4 units Quantity B 72 units 72 units Which of the following names the quantity and correctly explains why that represents the amount of matter present in the astronaut?

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.

Which accounts for an increase in the temperature of a gas that is kept a constant volume

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
