Integrated Concepts - (a) Suppose you start a workout on a Stairmaster, producing power at the same rate as climbing 116 stairs per minute. Assuming your mass is 76.0 kg and your efficiency is 20.0%, how long will it take for your body temperature to rise 1.00C if all other forms of heat transfer in and out of your body are balanced? (b) Is this consistent with your experience in getting warm while exercising?
hints: The ﬂask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet. You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t). after 10 minutes amount of water in the tank=66.84 ft3 t=69.3 minutes h(t)=e66.84t/100pi -1 h(10)=e66.84(10)/100pi -1=7.39 ft Height of stool=1.64 ft Height of water in the tank=7.39 ft Questions: show work How fast is the water rising? I would like to know how long I will have to hold my breath during the last part of the stunt.

True, False or Uncertain. Explain your answer. Own wage elasticity JELLlincrease if product demand elasticity n? is high. In short run, when there is an increase in wage rate, each firm will hire less labor and so the industry labor demand is simply the horizontal summation of firm's labor demand. а. b. Labor demand is represented by the marginal revenue produce schedule (MRP) when we have competitive product market while it will be represented by the value of marginal product schedule (VMP) when we have a product market monopolist. When elasticity of substitution, SLK, increase that means the L and K are less substitutable, and the isoquant will be L-shaped. Minimum wage imposed by the government is always bad for the economy because it increase unemployment and deadweight loss. с. d. e. 3.
