Alarge room in a house holds 947 kg of dry air at 33.2°c. a woman opens a window briefly and a cool breeze brings in an additional 62.4 kg of dry air at 13.2°c. at what temperature (in degrees celsius) will the two air masses come into thermal equilibrium, assuming they form a closed system? (the specific heat of dry air is 1006 j/ kg * °c, although that value will cancel out of the calorimetry equation.)

°c

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?

If y gets smaller as x gets bigger and y have an relationship?
