Chapter 14, Problem 51QAP
To determine

(a)

Predict the cost of 1 kg of ordinary ice if, ordinary ice (frozen H2O ) is cold, dry ice (solid CO2 ) is very cold, liquid nitrogen is extremely cold, and liquid helium is almost unimaginably cold!, the cost of each is approximately exponentially proportional to the temperature at which they change states, the temperature of dry ice is -78.5°C, and it costs about $1/kg, the temperature of liquid nitrogen is-196° C, and it costs about $2/kg, the temperature of liquid helium is-268° C, and it costs about $100/kg? Before you make the estimate, consider the most appropriate temperature scale to use.

To determine

(b)

How close is your estimate by checking the price of a bag or block of ice at your local grocery or convenience store?

I. Pushing on a File Cabinet Bob has been asked to push a heavy file cabinet down the hall to another office. It's not on rollers, so there is a lot of friction. At time t = 0 seconds, he starts pushing it from rest with increasing force until it starts to move at t = 2 seconds. He pushes the file cabinet down the hall with varying amounts of force. The velocity versus time graph of the cabinet is shown below. A. On the graphs provided below, 1. draw the net force vs. time that would produce this velocity graph; 2. draw the friction force vs. time for this motion; 3. draw the applied force (Fon Cabinet by Bob) VS. time for this motion (the first two seconds of this graph have been drawn for you). Velocity (m/s) Applied Force (N) Friction Force (N) Net Force (N) A -m B -U time (s) D time (s) time (s) time (s)
