A uranium and iron atom reside a distance R = 44.90 nm apart. The uranium atom is singly ionized; the iron atom is doubly ionized. Calculate the distance r from the uranium atom necessary for an electron to reside in equilibrium. Ignore the insignificant gravitational attraction between the particles. What is the magnitude of the force on the electron from the uranium ion?
Write down the complete hamiltonian of the helium atom in SI units and atomic units. Identify, with an explanation, the term in the hamiltonian which makes it nonseparable.
The intensity of the Sun's light in the vicinity of the Earth is about 930 W/m2. Imagine a spacecraft with a mirroredsquare sail of dimension 1.22 km. Estimate how much thrust (innewtons) this craft will experience due to collisions with theSun's ..
An early method of measuring the speed of light makes use of a rotating slotted wheel. A beam of light passes through a slot at the outside edge of the wheel, as in Fig. 10-31, travels to a distant mirror, and returns to the wheel just in time to ..

A segment of wire carries a current of 20 A along the x-axis from y=2.0 m to y=0 and then along the x axis from x=0 to x=-4.0 m. What is the magnitude of the force on this segment of wire
A particle of mass m moves on a smooth horizontal table. It is attached to a light, inextensible string that passes through a small hole in the table and carries a mass m, which hangs vertically. Find the Lagrangian of the system as a whole.
A pipe is open at both ends. Its length is 22.81 cm. If I excite standing waves in the pipe by blowing air over one of its ends, Find the distance between the antinodes at the two ends of the pipe
You wish to boil 1.1 kg of water, which has a specific heat capacity of 4186 J/kg-K. The water is initially at room temperature (293 K). Water boils at 373 K. How much energy must be added to the water by heating it in order for it to start boiling
A constant horizontal force Fa pushes a 1.50kg FedEx package across a frictionless floor on which a xy coordinate system has been drawn. gives package's x and y velocity components versus time t.
A 1kg ball is falling to the floor. When it is 0.7m above thefloor, it's potential energy exactly equals its kinetic energy. What is its speed when it reaches the ground
A woman with mass 53.5 kg is standing on the rim of a large disk that is rotating at 0.510 rev/s about an axis perpendicular to it through its center. Calculate the magnitude of the total angular momentum
A 7320 kg satellite has an elliptical orbit. The point on the orbit that is farthest from the earth is called the apogee and is at the far right side of the drawing. Find the work done by the gravitational force when the satellite moves from the ap..
