Consider a 100kg cyclist. He rides a road bike with road tires (which can be assumed to have negligible tread).
The cyclist is riding at 25km/hr and goes around a corner on a blacktop road without slipping. The corner can be assumed to have a radius of 10 m.
Set up an appropriate traction boundary condition (i.e., a traction vector) that approximately the rear tire’s interaction with the road.

An electron is confined to a box absorbs a photon with wavelength . As a result, the electron makes a transition from the n=1 state to the n=3 state. (a) Find the length of the box. (b) What is the wavelength ’ of the photon emitted when the electron makes a transition from the n=3 state to the n=2 state.Physics10 months ago
The figure shows two point sources of light, A and B. B emits light waves that are +p radians out of phase with the waves from A. A is 3λ from P. B is 5λ from P. (λ is the wavelength.) What is the phase difference between waves arriving at P from A and B?

The large gear (shown below) has a mass of 10 kg and a radius of gyration if 200 mm, while the small gear has a mass of 3 kg and radius of gyration of 80 mm. The system is at rest when a couple M of a magnitude of 6 N-m is applied rotating the small gear counter-clockwise. Neglecting friction, determine (a) the number of revolutions executed by the small gear before its angular velocity reaches 600 rpm and (b) the tangential force which the small gear exerts on the large gear. Note: The large gear has a radius of 250 mm and the small gear has a radius of 100 mm.1 AnswerPhysics1 year ago
