This is in regarding centripetal force (university physics 1): The London Eye Ferris wheel has a diameter of 120 m and rotates at 2 revolutions per hour. This is so slow that any change in perceived normal force is minimal. However, you decide it is your destiny to help tourists experience physics, so you increase its speed to 2 rpm...

A spherical raindrop 3.3 mm in diameter falls through a vertical distance of 4000 m. Take the cross-sectional area of a raindrop ,drag coefficient 0.45, density of water to be 1000 kg/m3, and density of air to be 1.2 kg/m3. (a) Calculate the speed a spherical raindrop would achieve falling from 4000 m in the absence of air drag 280...
Your answer is partially correct. Try again. Two point charges are lying on the y axis as in the figure: g- 320 pC and q +320, С they are equ distant from the pont e aneh les on the r axis s nans the magnitude of net electric field at P? (b) A small object of charge do 7.60 uC...
I'm not sure what im doing wrong A 0.40-Kg block slides along a small track with elevated ends and a flat central part. The flat part has a length L = 1.24 m. The curved portions of the track are frictionless, but for the flat part the coefficient of kinetic friction is 0.127. The block is released from rest from...
Following figure shows velocity -time graph of an object. a) Sketch the acceleration-time graph that correspond to this motion. b) Assuming the initial position is zero, determine the displacement of the object from beginning to t=8.0 seconds after it starts.
After taking off, a helicopter climbs in a straight line at a constant angle β. Its flight is tracked by radar from point A. Determine the speed and acceleration of the helicopter in terms of d, β, θ, and θ B В A d -
Programming Assignment PROGRAM NEEDS TO BE DONE IN C++ A furlong is a module of distance equal to 220 yards (1/8 mile). Write two classes that implement distances in the following manner: The first class keeps track of distances as a whole number of furlongs, a whole number of yards, and a number of feet, which may have a fractional...
4. Consider a circular loop of wire with a mass m and a radius R. The circular loop is vertical such that gravitational force on the loop points straight down. You may assume this is near the surface of the earth such that the force of gravity has a magnitude FGl mg. The upper half of the circular wire is...
