Sodium Chloride gas has molecules that are ionically bonded. The Sodium end has a charge of +1e, and the Chlorine has -1e (where "e" is the charge of the electron). These charges are separated by a distance called the "bond length"
Part A) Assume that the bond length is 2.361*10^-10 meters, calculate the dipole moment.
Part B) Convert your answer into units that chemists use: the Debye ("D")
A compressed spring shoots the block radically outward along a frictionless groove in the surface of the turntable. Illustrate what is the turntable's rotation angular velocity when the block reaches the outer edge?
A 20.00 kg wood ball hangs from the 1.10 long wires. The maximum tension the wire can withstand without breaking is 600 N. A 0.710 kg projectile travelling horizontally hits and embeds itself in the wood ball. What is the largest speed this projectil..
The potential difference between two parallel plates is 566 V. An alpha particle with mass of 6.64 10, What is the speed of the alpha particle when it reaches the other plate
The engineer has done a survey and found that almost no one complains if the force directed up the ramp is no more than 20 .Ignoring friction, illustrate at what maximum angle should the ramps be built, assuming a full 28 grocery cart?
The vector A s 3.50cm long and is directed into this page, In the right-handed coordinate system, where the +x-axis directed to the right, the +y-axis toward the top of the page
A hiker, who weighs 919 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 4410 N, and rests on two concrete supports, one on each end. He stops 1/3 of the way along the bridge.
How much longer does the trip take. Find out the acceleration of each mass and the tension in the string that connects them.
An electron is shot upward directly perpendicular to the lower plate of a parallel plate capacitor. Its initial velocity is 3.0 x 104 m/s. What must be the potential of the upper plate if the electron stops just before reaching it? The lower plate..
Two cicadas, Chirpy and Milada, jump from the top of a vertical cliff. Chirpy just drops and reaches the ground in 3.10 , while Milada jumps horizontally with an initial speed of 98.
A civil engineer wishes to plan a curved exit ramp for a highway in a way that a car will not have to rely on friction to round the curve without skidding. In the other words, a car moving at the designated speed can negotiate the curve even while th..
A parallel-plate capacitor is charged to an electric potential of 337 V by moving 3.95×1016 electrons from one plate to the other. How much work is done in charging the capacitor.
The flywheel of an engine has a moment of inertia 2.80 {rm kg} cdot {rm m} ^ {2} about its rotation axis. What is its final kinetic energy.
