Suppose the wavelength of light in a Michelson interferometer is 624 nm. How many dark fringes will be found if one mirror is moved a distance of 2.0 mm?
Force on a Particle A force F = (4.0 N)i + (c N)j acts on a particle as the particle goes through displacement d = (4.0 m)i - (2.0 m)j. (Other forces also act on the particle.) What is the value of c if the work done on the particle by force F is eac..
A spring is hanging from the ceiling. Attaching a 700 physics book to the spring causes it to stretch 27 in order to come to equilibrium. Spring constant 25 N/m: -From equilibrium, the book is pulled down 10cm and released. What is the period of osci..
A mover finds that a 20 kilogram crate initially at rest requires a 75 Newton horizontal force to set the crate in motion, but only a 60 Newton force to maintain a constant velocity. Obtain coefficient of static friction between crate and floor
