14 Explain in terms of conservation of energy why sweating cools your body, even though the sweat is at the same temperature as your body. Describe the forms of energy involved in this energy transformation. Why don't you get the same cooling effect if you wipe the sweat off with a towel? Hint: The sweat is evaporating.
Let T:P R^2 be defined by T(p(x)) = (p(1),p(-1)). (a) Find T(p(x)) where p(x) = 2 + 5x. (b) Show that T is a linear transformation. (C) Find the kernel of T. Explain why T is one-to-one. (d) Find the range of T. Explain why I' is onto. (e) Find T-1(3,7)

o Show enough work to guide your reader through the steps (but not every gory detail of arithmetic or algebra is needed). o Draw the diagrams necessary to apply the principles (in this case vector diagrams-whatever vectors are calculated must be drawn and supported with triangles). Hand write your solution, or use Mathcad. Do not use a word processing application for math (too time consuming). If using Mathcad, hand-draw the...

14-34 A water pump is used to pump water from one large reservoir to another large reservoir that is at a higher elevation. The free surfaces of both reservoirs are exposed to atmo- spheric pressure, as sketched in Fig. P14-34. The dimen sions and minor loss coefficients are provided in the figure. The pump's performance is approximated by the expres- sion Havailable H av?, where the shutoff head H 40 m of water column, coefficient a = 0.053 m/Lpm?, available...

Question 3 Consider the one-dimensional harmonic oscillator, and denote its properly normalised energy eigenstates by { | n〉, n = 0, 1, 2, 3, . . .). Define the state where α is a complex number, and C is a normalisation constant. (a) Use a Campbell-Baker-Hausdorff relation (or otherwise) to show that In other words, | α > is an eigenstate of the (non-Hermitian) lowering operator with (complex) eigenvalue α. (b) During lectures...

A storm approaches an office and the air pressure outside suddenly drops from 1.013 kPa to 0.960 kPa. Before the pressure inside the office has time to change, what is the magnitude of the overall force exerted on an external window of the office with dimensions 1.2 m by 1.8 m?

Review Constants Periodic Tab Part A The gas-phase reaction of NO with F to form NOF and has an activation energy of E. = 6.30 kJ/mol and a frequency factor of A = 600-108 M. The reaction is believed to be bimolecular NO(s)+F2(g) NOF(g) + F(g) where NO is a free radical. Free radicals, species with an odd number of unbound electrons tend to be more reactive. This is one reason by NO reacts so readily with gases such as...
