Note that xcritical, as computed in the previous part, is not necessarily positive. if xcritical< 0, the bar will be stable no matter where the block of mass m2 is placed on it. assuming that m1, d, and l are held fixed, what is the maximum block mass mmax for which the bar will always be stable? in other words, what is the maximum block mass such that xcritical≤0? answer in terms of m1, d, and l.

Several processes form metal ore. match each process to its description. volcanic activity weathering hydrothermal energy rocks break down as they interact with air and water. arrowright density differences and other factors cause metals to concentrate in igneous rocks. arrowright seawater heats up from contact with hot rock, and metals dissolve in it. the water rises and contacts cooler water, causing metal ores to settle on the ocean floor. arrowright

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?

How to tell if two objects are in thermal equilibrium 1.the objects have the same temperature 2.the objects are the same size 3.the objects are touching each other 4.the objects temperatures are changing
