Tsunamis are fast-moving waves often generated by large underwater earthquakes. in the deep ocean, their amplitude is barely noticeable, but upon reaching shore, not complete marked out ofwhat is the speed of the wave? they can rise up to the astonishing height of a sb-story buiding. one tsunami, generated off the aleutian islands in alaska, had a wavelength of 730 km, and travelled a distance of 3830 km in 6 30 hours (note: this is given in decimal format, not as hours and minutes). 1.00 m/s ,flag question check question 7what is the period of the wave? not complete marked out of 1.00 , flag question check

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
