Oil has a density ? of 860kg/m3. An oil droplet is suspended between two plates 1.0cm apart by adjusting the potential difference between them to 1177V. When the voltage is removed, the droplet falls and quickly reaches constant speed. It is timed with a stopwatch and falls 3.00mm in 7.33s. The viscosity of air is 1.83

A tetherball set has a ball with mass 0.411 kg and a nylon string with diameter 2.50 mm, Young's modulus 4.00 GPa, and density 1150 kg/m3.

A tetherball set has a ball with mass 0.411 kg and a nylon string with diameter 2.50 mm, Young's modulus 4.00 GPa, and density 1150 kg/m3. The nylon string has a length of 2.200 m when the ball is at rest (hanging straight down). While playing tetherball, Monty hits the ball around the pole so it moves in a horizontal circle with the string at an angle of 65.0° to the pole. (a) How much does the string stretch compared...

An 80 kg skydiver falls through air with a density of 1.15 kg/m3 . Assume that his drag coefficient is C=0.57. When he falls in the spread-eagle position his body presents an area A1=0.94 m2 to the wind, whereas when he dives head first, with arms close to the body and legs together his area is reduced to A2=0.21 m2 . What are the terminal speeds in both cases?
