A sample started with 100 atoms of Element X. Sample X has a Half-Life of 5 years. If there are only 6 atoms of Element X left in the sample, how old is the sample, and how many Half-Lives have occurred? To answer the question, select the age of the sample AND the number of Half-Lives that have occurred.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
