The double slit is replaced by a single slit of width w = 0.036 mm and is illuminated with an intense light source of wavelength 528 nm, to produce a diffraction pattern on the screen. The screen is moved closer, now a distance of L = 0.469 m from the slit. Discover the distance, on the screen, of the 4th dark fringe from the central bright maximum of the pattern. Do not use the small-angle approximation.
A camera is equipped with a lens with a focal length of 23 cm. how far from the film should the lens be placed
A 80 kg diver steps off a 13 m tower and drops from rest straight down into the water. If he comes to rest 4.1 m beneath the surface, find out the average resistance force exerted on him by the water.
A 3-point jump shot is released 2.2 m above the ground, 6.02 m from the basket, which is 3.05 m high. For launch angles of 30° and 60°, discover the speed required to make the basket?
A 100g ball on a 50 cm long string is swung in a vertical circle about a point 200 cm above the floor. obtain the tension in the string an instant before it broke
A racetrack is to have a banked curve with radius 225 m. What should be the angle of the bank if the normal force alone is to allow safe travel around the curve at 56.0 m/s
an open vertical tube has water in it. a tuning fork vibrates over its mouth. as the water level is lowered in the tube
A simple harmonic oscillator takes 17 seconds to undergo 17 complete oscillations. What is the frequency of the oscillator
To measure the speed of light, Fizeau used a rotating disk with equally spaced holes during which light could pass. Light was directed at the rotating disk, passed during one of the holes, bounced from a distant mirror, and then the angular speed of ..
A simple harmonic oscillator consists of a block of mass 4.10 kg attached to a spring of spring constant 350 N/m. What is the amplitude of the oscillations
You throw a ball torwards a wall at speed 21 m/s and an angle of 40 degrees above the horizontal. The wall is 22.0 m from the release point of the ball.
A penny has a mass of 2.50 g, a diameter of 19.55 mm, find the density of the material from which the penny is made
You make tea with 0.375 kg of 94.6°C water and let it cool to room temperature (20.0°C) before drinking it. Calculate the entropy change of the water while it cools.
