The length of nylon rope from which a mountain climber is suspended has a force constant of 1.38 x 104 N/m. (a) What is the frequency (in Hz) at which he bounces, given that his mass plus the mass of his equipment is 87.0 kg? 2 Hz (b) How much would this rope stretch (in cm) to break the climber's fall if he free-falls 2.00 m before the rope runs out of slack? Hint: Use conservation of energy. 56 cm (c) Repeat both parts of this problem in the situation where twice this length of nylon rope is used. frequency (in Hz) 1.417 Hz stretch length (in cm) 83.7 X cm
(a) Calculate the range of wavelengths (in m) for X-rays given their frequency range is 30,000 to 3.0 x 107 THz. smaller value 0.01 X m larger value 10 Xm
A doctor examines a mole with a 14.5 cm focal length magnifying glass held 12.5 cm from the mole. (a) Where is the image? (Enter the image distance in meters. Include the sign of the value in your answer.) 8/725 Xm (b) What is its magnification? 62/725 X (c) How big in millimeters is the image of a 5.10 mm diameter mole? 36.975 mm
