Near the critical temperature and critical pressure of a gas, itwill behave quite like an ideal gas except that its density will be higher than predicted by the Ideal Gas Law. Based on what you know of this "compressibilty" behavior, what will be the volume in m3 of 7.25 kg of methane if it is at a temperature of 200.65 K, and a pressure of 2.784 MPa?
The source of a sound wave has a power of 8.34μW. If it is a point source, (a) what is the intensity and (b) the sound level at 2.29 m. distance?
Weak magnetic fields can be measured at the surface of the brain. Although the currents causing these fields are quite complicated, we can estimate their size by modeling them as a current loop around the equator of a 18--diameter (the width of a ..
A 1.5 kg playground ball is moving with a velocity of 3.0 m/s directed 30 degrees below the horizontal just before it strikes a horizontal surface. evaluate the magnitude of the average resultant force on the ball

alex and bob are twins working on a space station located at a fixed position in deep space. alex undertakes an
A ladder weighs 150N, is 5 meters long, and is leaning against a frictionless wall at an angle of 30 degress with the horizontal. A person who weighs 300N is 2/3 the way up the ladder. The ground has an unknown coefficient of friction. What is the mi..
A person with mass m1 = 52 kg stands at the left end of a uniform beam with mass m2 = 109 kg and a length L = 3.1 m. What is the location of the center of mass of the system
Calculate the energy of the planet, perihelion and aphelion distances and the speed of the planet at these points - Explain why hurricanes spin counter clockwise in the Northern hemisphere and clockwise in the Southern hemisphere.
Calculate the semimajor of a moon on a synchronous orbit around Mars. Express your answer in martian radii (Rmars) from the center of the planet. compare this distance with the orbits of phobos (at 2.76 Rmars) and Deimos (at 6.9 Rmars).
An airplane is flying at 175km/hr on a headwind of 45 degrees. The wind is blowing from 300 degrees at 45 km/hr. Find the direction and magnitude of the plane's velocity
