I WILL MARK U BRAINLIEST PLZ HELP ME Two ships are on opposite shores of a narrow sea channel. At the same time, they start moving toward each other at different, but constant speeds. When they pass each other the first time, they are 7.0 km from one shoreline. They continue to the opposite shore, then turn around and start moving toward each other again. When they pass for the second time, they are 3.0 km from the other shoreline. Ignore any effects from winds, waves, or currents, and don’t worry about the ships accelerating, or stopping at the shorelines. How wide is the sea channel?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
