- A 19.3-g mass of gold in the form of a cube is 1 cm long on each side (somewhat smaller than a sugar cube). What would be the length of the sides of a cube that has twice this mass of gold?What is the correct answer to this problem? Some people got about 360J and others got around 570J, I really need help on figuring this out because it's really confusing me...Within a certain type of star called a neutron star, the material at the center has a mass density of 1.0 x 1018 kg/m³.

- Global warming is a cause for concern because even small changes in the Earth’s temperature can have significant consequences. For example, if the Earth’s polar ice caps were to melt entirely, the resulting additional water in the oceans would flood many coastal areas. Model the polar ice as havingmass 2.30 × 1019 kg and forming two flat disks of radius 6.00 × 105 m. Assume the water spreads into an unbroken thin, spherical shell after it melts. Calculate the resulting change in the duration of one day both in seconds and as a percentage.A sphere made of either brass or aluminum has a radius r= 10cm. What is its mass?The answer is supposed to be v=2.56m/s but I'm not sure how to write out the problem.
