• ### What is the Pressure inside the container?

A cook puts 5.80 g of water in a 2.00-L pressure cooker that is then warmed to 480°C. What is the pressure inside the container? (Assume room temperature is 20°C.)

• ### Calculate the absolute pressure at an ocean depth of 150m.?

Calculate the absolute pressure at an ocean depth of 150 m. Assume the density of sea water is 1 024 kg/m3 and the air above exerts a pressure of 101.3 kPa

• ### Seismic Waves question?

A seismographic station receives S and P waves from an earthquake, separated in time by 15.4 s. Assume the waves have traveled over the same path at speeds of 4.50 km/s and 7.50 km/s. Find the distance from the seismograph to the focus of the quake

• ### Doppler Effect problem?

Standing at a crosswalk, you hear a frequency of 500 Hz from the siren of an approaching ambulance. After the ambulance passes, the observed frequency of the siren is 409 Hz. Determine the ambulance's speed from these observations. (Take the speed of sound to be 343 m/s.)

• ### Solution to the Wave Equation?

How would you show/prove that the following is or is not a solution to the wave equation?

(e^-x)*sin(kx-wt)

The Wave Eqn: [http://hyperphysics.phy-astr.gsu.edu/hbase/waves/i...

• ### What is the average force exerted by the wall on the ball? (Fx and Fy)?

A 3.10-kg steel ball strikes a wall with a speed of 11.0 m/s at an angle of θ = 60.0° with the surface. It bounces off with the same speed and angle.. If the ball is in contact with the wall for 0.200 s, (Assume right and up are the positive directions.)

• ### Working with Vectors. What is A and B?

Given the following Vectors: A+B= x1i + y1j and A-B= x2i + y2j what is A? and what is B?

I am quite lost here..

• ### ln(6x+2)=2ln(x+1)+ln2?

solve the equation..

• ### At what time are the trains 400 miles apart?

Two trains leave the railroad station at noon. The first train travels along a straight track at 90 mph. The second train travels at 75 mph along another straight track that makes an angle of 130 degrees with the first track.

• ### Are 129,000 miles on a 2001 BMW 325Ci too many?

I'm looking to buy myself a used car for school/ work and day to day stuff. I came across this BMW, and it checks out perfectly, I'm just not too sure about the miles. Any help/ suggestions, I appreciate!

• ### Is it possible to apply for only one semester in college/university?

because next year i will move and it would be easier to get accepted when I am/ was already enrolled in a college/uni.

• ### Where can I watch Man vs. Wild "worst case scenario" ?

I don't have the discovery channel any longer. is there a way to watch it online?

• ### What do you think of this? • ### What is the Potential Difference of this situation?

An electron is initially at rest on the surface of the sphere:

At a point P, the speed of the electron is 6.0x10^6 m/s. Determine the potential difference between Point P and the surface of the sphere?

(I'd like to know how to reach this answer as well)

• ### Where can I skydive in Michigan?

I am a certified skyjumper, so I just want to know if there is a place somewhere near Detroit to skydive.
