A 5 litre pressure vessel contains 200g of propane. Using the Peng Robinson EOS calculate the pressure in the vessel at 50oC. What state is the propane likely to be in?
Approximately how much electricity is generated from nuclear power each year in the US? Given the average fuel burnup above, calculate a yearly average demand for reactor fuel and SWU for the US.
An electric power line carries a current of 1400 A in a location where the earth's magnetic field is 6.0 ? 10-5 T. The line makes an angle of 75° with respect to the field. Determine the magnitud
A ship has a top speed of 3.0 m/s in calm water. The current of the ocean tends to push the boat at 2.0 m/s on a bearing of due South. What will be the net velocity of the ship if the captain poin
A DC circuit has a single battery of voltage V = 10.0 V attached to a resistor R = 100 Ohms. If the voltage is increased to 20.0 V, then by what factor does the power emitted by the resistor increa
Daggett turns his living room into a giant "turntable," but forgets to pin down the furniture. As a result, the furniture flies off the turntable as it begins to spin. If a constant torque is bein
How many joules of potential energy does 1.5-kg book gain when it is elevated 2 m? when it is elevated 4 m(let g= 10 N/kg)calculated the number of joules of kinetic energy a 1-kg parrot has when it
The Young Modulus of a metal wire is 0.17 TPa and it's cross-sectional area is .18mm^2. The wire is extended by a force . This causes the length of the wire to be increased by 0.095%. What is the a
Given an object with mass equal to the standard kilogram, how would you determine if a force applied to it has magnitude equal to one newton?
How many side-by-side atomic chains (long springs) are there in this wire? This is the same as the number of atoms on the bottom surface of the nickel wire. Note that the cross-sectional area of one
A 35 kg uniform ladder is leaned against a building. The 5 m tall ladder makes an angle of 60 degrees with the ground. The ladder encounters a coefficient of static friction from the ground of 0.3 a
Three long parallel wires are 3.8 cm {\rm cm} from one another. (Looking along them, they are at three corners of an equilateral triangle.) The current in each wire is 9.50A A , but it
A common misconception is that the current is "used up" and steadily declines as it progresses through a series of resistors. That would be a violation of conservation of charge. What is actually us
People often use the term energy crisis, implying that we are running out of energy. How can this be if energy is conserved? If we are not running out of energy, what are we really running out o
