Energy Transformation on a Roller Coaster
A roller coaster ride is a thrilling experience that includes a wealth of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride frequent begins as a chain and motor (or another mechanical device) exerts a force on the train of cars to lift the train to the top of a very tall hill. Once the cars are lifted to the top of the hill and gravity takes over and the remainder of the ride is an experience within energy transformation.
A guitar string produces 4 beats/second when sounded with a250Hz tuning fork and 9 beats/second when sounded with a 255 Hz tuning fork. What is the vibration frequency?
Q. I n a Newton's ring experiment, the wavelength of the light used is 6 × 10 -5 cm and the difference of square of diameters of successive rings are 0.125 cm 3 . What will h
