Ideally, the angular momentum before a collision is equal to the angular momentum after collision. How does the kinetic energy of the spinning disk before collision compare to the kinetic energy of the combined disks after collision

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels.the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause,directly and indirectly, for such a rise in sea level is
