Aplane is flying east at 135 m/s. the wind accelerates it at 2.18 m/s squared directly north east. after 18.0s, what is the displacement (magnitude and direction) of the plane?

In a system, when potential energy decreases, then entropy also decreases. true false

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator.
