Given the dry adiabatic lapse rate of air is dtaz =-g/cp, where t = air temperature, z = elevation, cp-specific heat at constant pressure, g- gravity, compute dt/dz in °c/km if j oc.1 kg. if air temperature is 20°c and vapor pressure of air is 12.2 mb, estinate the elevation the air parcel must rise before the vapor pressure of air becomes saturated, assuming the lapse rate is 7°c/km. note l joule= 1 nm, 1 newton= 1 kg. m/sec2 c,-1004

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
