Tom tried to measure the wavelength of light from a laser pointer with unknown specifications. He sent the laser through two very small slits and observed bright-dark fringes on the wall 2 meters from the slits. The distance between two neighboring bright lines in the center was measured to be 1 mm and the distance between two slits was also measured to be 1 mm. What is the laser wavelength

What is the momentum of a 2 kg object moving at 15 meters per second

In a good thermo flask the main cause of heat loss is

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
