Answer:
285 kJ
Explanation:
potential energy
= m g h
= 95,000 g × 10 m/s² × 300 meters
= 95 kg × 10 m/s² × 300 meters
= 950 kgm/s² × 300 meters
= 285,000 J
= 285 kJ
True !! size dependent properties state is only one of the many physical properties of matter some physical properties such as massive value depending on the size or the amount measures of these properties very depending on how much matter is in a sample.
50g U ( 1mol/ 238.03g) = .2 moles
238.03 is the molar mass of uranium- can be found on periodic table
The correct answer would be 2
