How manyuniversities benefitted when an emeritus professor won a distinguished award (which has included NobelPrizes in the past)? The fact of the matter is, given the cost-benefits of granting emeritus status, anyuniversity in question has always been far-and-away the winner.
where g is the acceleration of gravity. The value for g on Earth is 9.8 m/s/s. The above equation can be used to calculate the velocity of the object after any given amount of time when dropped from rest. Example calculations for the velocity of a free-falling object after six and eight seconds are shown below.
It depends what mass is present. 1 drop of water will cool down instantaneously. 1 tonne will take considerably longer. It also depends on what temperature it is being cooled down to. If it were being cooled to 99 0C it would only take a 1 kg mass a few seconds but if it were to 10 0C it would take considerably longer. Another major factor is the temperature gradient between the water and the surroundings.
