Abrine solution of salt flows at a constant rate of 99 l/min into a large tank that initially held 100100 l of brine solution in which was dissolved 0.10.1 kg of salt. the solution inside the tank is kept well stirred and flows out of the tank at the same rate. if the concentration of salt in the brine entering the tank is 0.020.02 kg/l, determine the mass of salt in the tank after t min. when will the concentration of salt in the tank reach 0.010.01 kg/l?

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
