The jet streams follow the contours of low and high pressure areas (troughs and ridges), which move like waves in the atmosphere across the earth. Imagine a trough is sitting over the town where you live. Predict the type of winter weather you are experiencing. A) warm and dry B) mild and rainy C) very cold and snowy D) very cold but sunny

Abearing is designed to a reduce friction b. support a load c.guide moving parts such as wheels, shafts and pivots d. all of the above

The force will determine the acceleration.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
