I start walking. The 1st leg of my trip I walk dA = 135 m at θA = 16° south of east. The 2nd leg of my trip I walk dB = 75 m at θB = 16° north of east. On my final leg I walk dC = 75 m at θC = 64.5° north of west. Choose the coordinate system so that x is directed towards the east, and y is directed towards the north. a)Write an expression for the x-component of the final displacement in terms of the given quantities.
b)Write an expression for the y-component of the final displacement in terms of the given quantities.
c)What is the magnitude of my displacement vector (in meters) as measured from the origin?
d)What is the angle of my displacement vector as measured counterclockwise from the +x-axis?

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
