A rectangular ship (300 meters by 50 meters) weights 450,000,000 Newtons, how much of the ship is submerged underwater?

If the top surface of a submersible is at a depth of 1000m, what is the hydrostatic pressure on the top surface (assuming water ρ = 1000 kg/m3)?

(a) 9810 Pa (b) 0.981 Pa (c) 9.81 Pa (d) 1,000,000 Pa (e) 9,810,000 Pa

If the bottom surface of the submersible is at a depth of 1000m, what is the hydrostatic pressure on the bottom surface (assuming water ρ = 1000 kg/m3)?

(a) 9810 Pa (b) 0.981 Pa (c) 9.81 Pa (d) 1,000,000 Pa (e) 9,810,000 Pa

What is it?

(a) conservation of mass for a system (b) divergence theorem (c) continuum hypothesis (d) Cauchy’s rule (e) all but d

Consider a steady incompressible laminar flow of water (density ρ and kinematic viscosity ν) between two infinite (in x direction) flat plates A and B. Plate A located at y = 0 is stationary while plate B located at y = h moves at speed U in the positive x direction. We seek the solution for velocity component u by considering the x-component of the Navier-Stokes equation.

I need help with the first four questions, all the other ones arent too bad

http://sdcc3.ucsd.edu/~ir118/Summer2011/MAE101AS11...

I need to find the minimum from 0 to 30 m/s for the equation y=10000*(1-((x-15)./30).^2) where x is the velocity, using numerical integration. Ode45 might be helpful here, but idk how to use it. x ranges from 0 tto 45 m/s.

Mendenhall v Carolina

a closed 5-m-tall tank, is filled with water to the depth of 4 m. the top portion of the tank is filled with air which as indicated by a pressure gage at the top of the tank, is at the pressure of 20 kPa. Determine the pressure that the water exerts on the bottom of the tank

a rope of mass M and lenght L is released from rest with a very small amount of it hanging over the edge of a table. determine the speed of the rope as a function of s. assume the surface is smooth (aka frictionless)

i know you have to use energy to solve this, but i dont know how to make the potential energy and kinetic energy related to each other.

i got a new laptop today and the laptop is named Benny, was this a laptop someone returned and i got it? or is it truely new?

what are your picks?

cowboys at vikings

jets at chargers

ravens at colts

cardinals at saints

Who wins and why?

i want unbiased picks for this game.

What do you think will happen in this weekend games?

Ravens @ Colts: Ravens win on last second field goal, 31-28. Colt starters will be rusty. And Ray Rice is a beast. Brady turned it over, so will Peyton (not as much though, maybe 2 ints).

Cardinals @ Saints: Cardinals in a shoot out, 34-28. The Saints looked awful at the end of the season (how do you lose to the Bucs!?!?) and after least week we know Arizona can score.

Cowboys @ Minnesota: Tough game to pick, I'm going with Minnesota just because of their defense, 17-14.

Jets @ Chargers: Teams don't do well when they travel to the opposite coast. The Jets cannot contain Floyd, Gates, and Jackson. The Jets running game is awesome, but will be abanoned if they fall behind early. I don't like rookie quarterbacks under that kind of pressure (I'm a USC fan so i actually like Sanchez). The Jets defense limits the Chargers offense, but doesn't stop them. Chargers win, 28-17.

So, your picks?

Learning Goal: To understand how the two standard ways to write the general solution to a harmonic oscillator are related.

There are two common forms for the general solution for the position of a harmonic oscillator as a function of time t:

1. x(t) = Acos(omega t + phi) and

2. x(t) = Ccos(omega t) + Ssin(omega t).

Either of these equations is a general solution of a second-order differential equation F=ma; hence both must have at least two--arbitrary constants--parameters that can be adjusted to fit the solution to the particular motion at hand. (Some texts refer to these arbitrary constants as boundary values.)

How do you express the phase angle (phi) in terms of C and S?

The time required for the solution y of the growth problem

y'=ky k>0 y(0)= y0

to reach twice its original value is called the doubling time.

Suppose that the solution of the above IVP has value B at any t1 time . Determine the value of the solution at time t1+td.

The answer will not include a k or t.

Thanks a lot

two really good match ups but i can only start one
