The other end of the rope is terminated so...One mole of an ideal gas initially at a temperature of Ti = 7.2°C undergoes an expansion at a constant pressure of 1.00 atm to three times its original volume. Express the rate of flow Q in terms of b, d_1, and d_2.If atom is the basic unit of life, does that make biology a branch of physics?Give a one-word term for: 1. changing momentum.

While warp drive is pure fiction, antimatter is very real. Then...Unpolarized light whose intensity is 1.30 \;W/m^2 is incident on the polarizer in the figure.
The mixture is then heated until its temperature is 165 ? Questions and Answers A plant, for example, absorbs sunlight and uses its energy to make complex sugar molecules while radiating heat back into the environment.Understanding these complex systems “is the great unsolved problem in physics,” says Stephen Morris, a University of Toronto physicist.

What fraction of the light intensity is transmitted?In a stack of three polarizing sheets the first and third are crossed while the middle one has its axis at 30 degrees to the axes of the first one. It is connected to a large line in which oxygen at 1 MPa, 50C, is flowing. Knowing that the speed of each train is constant and that B reaches the crossing 10 min after A passed through the same crossing, determine...A 3 \ kg sprocket wheel has a centroidal radius of gyration of 70 \ mm and is suspended from a chain as shown.

A) What is the total electric flux due to these two p...What is the driving force for (a) heat transfer, (b) electric current, and (c) fluid flow?Write the first five terms of the Madelung constant for a two-dimensional lattice of alternating positive and negative ions.In which areas is acid rain a major problem and why?Who contributed to general relativity, quantum gravity, and black holes?In a church choir loft, two parallel walls are 5.30 m apart. Physicists build computer simulations. After passing through both polarizers the intensity is I_2 = 280 W/m^2. The initial temperature and pressure of the gas are 460 K and 2.80 atm. The helium first expands at constant pressure until its volume has doubled. Calculate the fo...(a) How much pressure is needed to compress the volume of an iron block by 0.11%? (a) What is the final pressure? The CO2 undergoes the following two processes: Process 1-2: adiabat...The 15 kg block A and 23 kg cylinder B are connected by a light cord that passes over a 5 kg pulley (disk). Some physicists hoped that Since Einstein, physicists have thought of space and time as forming a four-dimensional structure known as “spacetime.” But space differs from time in some very fundamental ways. When the angle of incidence is 60.0 degrees, the reflected light is completely polarized parallel to the surface of the glass.
