The sound tube experiment was performed in gas Carbon Dioxide at temperature 20 deg. C. The students partnering on the bench obtained for the slope of the straight line fitting of the experimental points the value 365.0. Compare the speed of sound following from that slope to the calculated speed of sound from the gas properties? For CO2, Cp/Cv = 1.289, and the mass of one mol CO2 is 0.044 kg. The sound tube length is 0.367 m. The additional necessary datum is given in the text.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

The act of moving from one place to another. a. locomotor b. aerobic c. stationary d. static
