The temperature a 200 mL of gas originally at STP is changed to -25^circ C at constant volume. Calculate the final pressure of the gas in mmHg.3. Two solid circular cylinders made of the same substance (shear modulus=10^10N/m^2) and of the same length are subjected to torques which twist both cylinders through a twist angle equal to 1^circ The torques are in the ratio of 9 to 1. (a) What is the ratio of the radi of the cylinders?2. The shear modulus of aluminum is 2.62times 10^10N/m^2 . of copper 4.83times 10^10N/m^2 and of glass 2.00times 10^10N/m^2 If you have identical pieces (i.e., same dimensions)of aluminum, copper, and glass , which one would twist most easily?1. A mass is hung on a tendon of length 20 cm and cross- sectional area 2mm^2 . The tendon stretches 1 cm. If Young's modulus for the tendon is 2times 10^7N/m^2 what mass was hung on the tendon?8) What is the focal length of a makeup mirror that produces a magnification of 1.So when a person's face is 12.0 cm away?PREV 424344454647484950 NEXT
