An earthquake in the ocean floor can generate a tsuname wave.Although barely noticeable while traveling in the deep ocean, atsunami can reach a height of over 60ft when it breaks at theshore. A particular tsunami which originated near theAlaska coast had wavelength 470 miles and traveled 2300 miles in5.3 hr. Determine the wave's (a) speed (in miles/hr and m/s) (b)frequency (c) period (in seconds and in minutes)

Thanks for your help, it is greatly appreciated!

1. The USS Farragut (DDG-99) Guided Missle Destroyer) displaces9200 long tons (1 long ton= 2240 lbs) of seawater. Assuming theaverage density of seawater surrounding the ship is 1.024 g/mL,calculate the total volume of seawater(in m^3) displaced by theship's hull.

2. A cargo ship of 455 ft. length, 62 ft. beam, and 38 ft. depth(deack to keel) has been loaded so much that is displaces 15,036.75m^3 of seawater (assume a uniform density of 1.024 g/m). What isthe total weight of the cargo ship (in kg) with its present load?If you first calculate the ship's overall volume, what is theship's overall density (in g/mL)? If there was a hull breach, howmuch seawater (in m^3) could she take on before sinking?

3. Your ship is in the middle of the Pacific Ocean, in waters 4500meters deep. While enjoying the day on deck, a breeze picks up atiny grain of quartz sand (0.3 mm diameter, 2.65 g/mL) in your hairand carries it out to sea. If the sand grain is deposited on theocean surface, how long will it take to sink to the ocean floor(assuming a perfectly still ocean with a uniform density=1.024g/mL)?
v (setting)= (2r^2g(d(particle)-d(fluid))/9u

r=particleradius (m)

g= 9.8m/s^2

d=density (kg*m^-3)

u=(1.17*10^-6 m^2 s^-1)* d(fluid)

4. If the particle in Question 3 were a flake of dandruffinstead (1.035 g/mL), at what depth would the dandruff flake ceaseits descent in a layered ocean like the one dipicted here? How longwill it take for the dandruff flake to reach its final destination?Make sure you choose a meaingful unit of time; a simple algebraicmethod is fine.

1.017g/mL 500m

1.025g/mL 2000m

1.028g/mL 2600m

1.032g/mL 3175m

1.037g/mL 3800m

1.042g/mL 4500m

The deepest point in any ocean is in the Mariana Trench, which is about 11 km deep, in the Pacific. The pressure at this depth is huge, about  . (Take the bulk modulus of seawater to be .

a) Calculate the change in volume of 1.00 m^3 of seawater carried from the surface to this deepest point.

b) The density of seawater at the surface is 1.03x10^3 kg/m3. Find its density at the bottom.

c) Explain whether or when it is a good approximation to think of water as incompressible.
