If the human body temperature is 33 degreec, what is the wavelength of the emitted thermal radiation ? plot the spectral energy density emitted by the human body. do humans have significant emission in the visible region of the spectrum ? obs.: i() = (8pihc/^5)(l/(e^hc/kt - with k = boltzmann's cte; [1()] = j/m^

Within a pendulum, as potential energy decreases, energy increases. a. heat b. kinetic c. frictional d. gravitational

What pressure difference is required between the ends of a 2.0-m-long, 1.0-mm-diameter horizontal tube for 40 c water to flow through it at an average speed of 4.0 m/s?

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
