If two trains are traveling in the same direction as each other but at different rates of speed, one train travels farther in the same time than the other ... Explanation: Let the length of the train be L metres. Speed of first train = 3600 18 x L m/hour. Speed of secxond train = 3600 12 x L m/hour. When running in opposite directions, relative speed = 200 L + 300 L m/hour. Distance to be covered = L + L = 2L metre. Suppose two trains or two bodies are moving in opposite directions at u m / s and v m/s, then their relative speed is = (u + v) m/s. 7. If two trains of length a metres and b metres are moving in opposite directions at u m / s and v m/s, then time taken by the trains to cross each other = (a + b)/(u+v) sec. The movie at left shows how a standing wave may be created from two travelling waves. If two sinusoidal waves having the same frequency (and wavelength) and the same amplitude are travelling in opposite directions in the same medium then, using superposition, the net displacement of the medium is the sum of the two waves. a train 110 metres long is running with a speed of 60 2 trains travelling in opposite directions in what time will a 100 metre long train running with a speed of 50 km hr cross a pillar a 270 meters long train running if a 120 m long train takes 10 seconds to cross one gate what is the speed of the train a train 110m long passes a platform 90 m ... An observer at rest observing an object travelling very close to the speed of light would observe the length of the object in the direction of motion as very near zero. Then, at a speed of 13,400,000 m/s (30 million mph, 0.0447 c ) contracted length is 99.9% of the length at rest; at a speed of 42,300,000 m/s (95 million mph, 0.141 c ), the ... Standing wave, combination of two waves moving in opposite directions, each having the same amplitude and frequency. The phenomenon is the result of interference; that is, when waves are superimposed, their energies are either added together or canceled out. Learn more about standing waves.
