Consider a Young's two-slit experiment in which the wavelength of light is 45% smaller than the distance between the slits. How many complete dark fringes would be seen on a distant screen? (Assume for all these questions that the screen is as large as it needs to be.) How many total interference maxima would be seen on a distant screen? Now suppose that the wavelength of light is 126% larger than the slit separation. How many complete dark fringes would be seen on a distant screen?
A car accelerates from rest to a kinetic energy of 1.65 x 10^5 Joules in a distance of 646 m. How much force did the car's engine deliver to produce the change in kinetic energy.
A cat rides a merry-go-round while turning with uniform circular motion. At time t1 = 2.00 s, the cat's velocity is v1 = (5.50) i + (4.00 m/s) j, What is the magnitude of the cat's centripetal acceleration
