Q. A container of hot water at 50 degrees cools to 49 degrees in how many seconds when it is placed in a room that is t 20 degrees. use newton's law of cooling to estimate the time it will take for the container to cool from 50 degrees to 49 degrees?

Q. A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes a time of 3.00 s for the boat to travel from its highest point to its lowest, a total distance of 0.650m . The fisherman sees that the wave crests are spaced a horizontal distance of 6.50m apart.How fast are the waves traveling in m/s? What is the amplitude A of each wave in meters?
