Q. As observed from Earth, the wavelength of Hβ in the spectrum of the star Megrez in the Big Dipper is 486.112 nm. Laboratory measurements demonstrate that the normal wavelength of this spectral line is 486.133 nm. Is the star coming toward us or moving away from us? At what speed?
Q. A bicyclist of mass 61 kg (including the bicycle) can coast down a 6.00 degree hill at a steady speed of 8 km/h because of air resistance. How much force should be applied to climb the hill at the same speed and same air resistance?
A 23.00 kg chair initially at rest on a horizontal floor requires a 364N horizontal force to set it in motion. Once the chair is in motion, a 328N horizontal force keeps it moving at a constant velocity. A 23.00 kg chair initially at rest on a horizo..
An ocean liner leaves New York City and travels 34.0° north of east for 169 km. How far east and how far north has it gone? In other words, what are the magnitudes of the components of the ship's displacement vector in the subsequent directions.
A 1500 {rm kg} car skids to the halt on a wet road where mu_k = 0.50. How fast was the car travelling if it leaves 66-{rm m}-long skid marks.
A screen is placed 42.7 cm from a single slit that is illuminated with light of wavelength 677 nm. If the distance between the first and third minima in the diffraction pattern is 3.45 mm, what is the width of the slit.
A train is travelling up a 4.40 incline at a speed of 3.30 when the last car breaks free and begins to coast without friction. How long does it take for the car to come to rest? How far does the car travel.
Now the gymnast (not holding any additional mass) walks directly above right support. What is the force the left support exerts on beam.
A 1348 kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 13.6 s, then the motor stops. The rocket altitude 29.6 s after launch is 2091 m. You can avoid any effects of air resistance. What was the rock..
find the radius of curvature of the vertical profile of the road at A. Using value of the curvature found, determine the force exerted on a 160-lb driver by the seat of his 3100-lb car as the car, traveling at a constant speed of 50 mi/h, passes t..
What is the coefficient of kinetic friction between the crate and the floor. what height will the stream of water strike.
A 13g bullet traveling 223m/s penetrates a 2kg block of wood and emerges cleanly at 160 m/s. If the block is stationary on the frictionless surface when hit, how fast (m/s) does it move after the bullet emerges.
Suppose the player has a mass of 0.658 kg. How long might the player operate on the energy required to lift it through a height of 1.17 m.
