WebThis is made worse when the wave crests are at the ends of the ship, with a wavelength similar to ship length. Longitudinal Stresses created by Hogging and Sagging can be very severe and can cause a ship to break up. The stresses are resisted by all continuous longitudinal material especially those parts further from the neutral axis. Double ... WebThe waves created by the ship consist of divergent and transverse waves. The divergent wave are observed as the wake of a ship with a series of diagonal or oblique crests …

Web1 aug. 2024 · The number of lost ships (ship-like targets) was 7-8% for both Seasat-A and ERS-1. No false ships were detected. The number of lost or false wakes (wake-like features) was higher in ERS-1 images ... WebIt is also evident that a particle having greater energy will travel at high speed thus the wavelength of the propagating wave is less. Problem 1: Find the energy of the particle having a frequency of 66PHz. Given: h=6.626*10 -34 J.s nu =66PHz= 66*10 15 Hz We have, E=hnu = 6.626 *10 -34 *66*10 15 = 437.3*10 -19 Joules boomerang tv on amazon fire
