Moving water, like that of a river, carries sediment as it moves along its bed. the faster the water flows, the more sediment that is carried and the larger the sediment particles. as the river slows down, the heavier particles of the load will settle out. how can you explain the particle movement based on newton's laws of motion?

At an oceanside nuclear power plant, seawater is used as part of the cooling system. this raises the temperature of the water that is discharged back into the ocean. the amount that the water temperature is raised has a uniform distribution over the interval from 10° to 25° c. what is the standard deviation of the temperature increase?
