- What is wrong with the following expressions? How can you correct them? (a) C=AB , (b) C=AB , (c) C=AB , (d) C=AB , (e) C+2A=B , (f) C=AB , (g) AB=AB , (h) C=2AB , (i) C=A/B , and (j) C=A/B .Verify the normalization equation 0f(v)dv=1 In doing the integral, first make substitution u=m2kBTv=vvp. This "scaling" transformation gives you all features of the answer except for the integral, which is a dimensionless numerical factor. You'll need the formula 0x2e x 2dx= 4 to find the numerical factor and verify the normalization.`H.W A uniform glass rod having a length L is placed in the smooth hemispherical bowl having a radius r.

How much energy, in joules, does it take to raise a gallon of room temperature water, ~21.1°C, to boiling? Some useful values: kg gal Pwater = 3.79- J g°C Cw=4.18- 4. Consider the gallon of water from the scenario in the previous question. If we use a 600 square centimeter magnifying glass to focus the sun's light on the water, how long will it take to raise the water to boiling? Ignore any heat lost by the water during the process. Some useful values: The radiant power of the sun at noon on the Earth's equator is about 1,370 watts per square meter. That is 1,370 joules of energy every second over every square meter of the Earth near the equator.A fireworks show is choreographed to have two shells cross paths at a height of 162 feet and explode at an apex of 208 feet under normal weather conditions.

- = 1.30 x 104°C-1). At room temperature (20.0°C), the frames have circular lens A pair of eyeglass frames are made of an epoxy plastic (coefficient of linear expansion holes 2.23 cm in radius. To what temperature must the frames be heated if lenses 2.24 cm in radius are to be inserted into them?3. A converging lens with a focal length of 12 cm is placed at the center of a flat-end cylindrical glass tube of length 24 cm. The lens forms an insulated, airtight seal that creates two chambers of equal volume, and is free to slide like a piston within the cylinder. A mole of helium is injected into the left chamber, and a mole of molecular (diatomic) hydrogen is injected into the right chamber, and both chambers of gas are at the same temperature. A coordinate system with the lens at x = 0 has been introduced to simplify calculations (see "before" picture below). you before (T₁=T2, lens at x=0, image at x=-84cm) x=-12cm He x=0cm H₂ x=+12cm after (U₁=U₂, lens at x=?, image at x=?) x=-12cm He x=0cm H₂ x = +12cm With the equal-volume chambers enclosing equal numbers of moles of ideal gases at equal temperatures, the pressures must also be equal, which means the lens/piston doesn't move.
