A train is moving in the forward direction at 0.65c. The tracks are 1.5m apart and the light is at the center point between the tracks. An observer is 3m from the train when the beam is no longer visible (observer not in the beam). What half angular spread of the headlight beam does the train’s engineer see? Express in degrees.

Two slits are 0.08mm apart, and the screen is 1.5m away. How far is the 3rd dark fringe located from the central maximum if light of wavelength 600 nm is used? 3.75 cm 2.81 cm 3.75 m 2.81 m 2. Light (600nm) strikes a grating ruled with 350 lines/mm. What is the angular deviation of the 2nd order bright fringe? 21.1 degree 22 degree 24.8 degree 25.4 degree 3. What is light? What we see with our eyes a form...

A girl is sitting near the open window of a train that is moving at a velocity of 22.00 m/s to the east. The girl's uncle stands near the tracks and watches the train move away. The locomotive whistle emits sound at frequency 770.0 Hz. The air is still. (Use 343 m/s for the speed of sound in air for all parts of this question.) (a) What frequency does the uncle hear? Hz (b) What frequency does the girl hear?...

A train car with mass m1 = 576 kg is moving to the right with a speed of v1 = 7 m/s and collides with a second train car. The two cars latch together during the collision and then move off to the right at vf = 4.4 m/s. A)What is the initial momentum of the first train car? B)What is the mass of the second train car? C)What is the change in kinetic energy of the two train system...

A positive charge is moving along the x-axis in the positive direction. What is the direction of the magnetic field on the y-axis? A long straight wire lies along the y-axis carrying current in the positive y direction.What is the direction of the magnetic field at x = 3m, y = 3 m? What is the direction of the magnetic field at x = -3m, y = 3 m? A wire extends from x = - ∞ to x = 0...

Two trains, A and B, travel in the same direction on the same set of tracks. A starts at rest at position d, and B starts with velocity v0 at the origin. A accelerates with acceleration a, and B decelerates with acceleration –a. What is the maximum value of v0 (in terms of d and a) for which the trains don’t collide? Make a rough sketch of x vs. t for both trains in the case where they barely collide.

A train runs between 2 stations, 2 km apart at a average speed of 40kmph. The train is made to run according to the quadrilateral speed time curve. If the max speed is to be limited to 60 kmph, acceleration to 2 kmphps, coasting retardation to 0.15 kmphps and the braking retardation to 3 kmphps. Determine the duration of acceleration, coasting and braking.

A very metal train moving at a constant speed is passing a hippie observer on a platform. On one of the train cars, a Deathcore guitarist is continually hammering out a note at a frequency of 450 Hz. After the guitarist has passed, the hippie hears the sound with a frequency of 420 Hz. What is the speed of the train? Please explain work, I always rate!!:)

) Suppose a proton is moving in the +x direction at 3.00x105m/s and there is a uniform magnetic field of 0.100T in the –z direction. This field will tend to bend the path of the proton. a) We would like to design a device to make the proton continue straight in the +x direction. It will consist of two charged plates with a gap of 0.100[m] between the plates. Draw a diagram of where the plates should be and show...
