1) Because earth's rotation is gradually slowing, the length of each day increases: The day at the end of 1.0 century is 1.0 ms longer than the day at the start of the century, In 30 centuries, what is the total of daily increase in time?
2) (a) assuming that water has a density of exactly 1 g/cm3. Find the mass of one cubic meter of water in Kilograms.
(b) suppose that it takes 10.0 hours to drain a container of 5700 m3 of water. What is the "mass flow rate" in Kilograms per second, of water from the container.
3) A vertical container with base area measuring 14.0 cm by 17.0 cm is being filled with identical pieces of candy, each with a volume of 50.0 mm3 and a mass of 0.0200 g. Assume that the volume of the empty spaces between the candies is negligible. If the height of the candies in the container increases at the rate of 0.250 cm/s, at what rate (Kilograms per minute) does the mass of the container in the container increase? Please provide with a step by step solution and with explanations if possible.
