Part B. Note that the origin of the axes is at the legs of the snowboarder for time t = 0. The plot for the "Legs" has been marked up to t
= 0. You need to complete the Legs plot across the screen from point t = 0 onward.
To do so, mark the Legs position on every frame by holding down the Shift key and clicking the mouse (crosshair cursor) as the
video automatically steps through the video clip. See how to plot points e.

Hint: Zoom your browser display to at least 125% for this marking step, to get the best accuracy in marking the center of the
"marker patch" on each frame. After you've plotted the rest of the points for the legs, return your browser's "zoom" setting to
10096.
Now look at the graphs for the horizontal and vertical displacement of the legs against time.
How do the two graphs, x vs. t and y vs. t appear? What can you say about the displacement of the snowboarder?

The intensity, or loudness, of a sound can be measured in decibels (db), according to the equation , where i is the intensity of a given sound and is the threshold of hearing intensity. what is the intensity, in decibels, [i(db)], when ? use a calculator. round to the nearest whole number. 8 9 19 80

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.
