A useful model of a water molecule is sketched in the figure below, with point charges of 5.2 10-20 C at the H sites and a point charge -10.4 x 10-20 C at the O site. The H-O bond length is 9.6 10-11 m, and the bond angle is theta = 104°.
The diagram is simply Oxygen with two H with theta angle drawn between Hydrogens.
a. What is the total electric potential energy of this model of a water molecule?
b. How much work would be required to completely disassociate the molecule?
A hot-air balloon is travelling upwards with a constant speed of 12 m/s. An object fell from the balloon when it was at the height of 1000 m
A child of mass 24 kg sits 2.10m to the left of the center of a seesaw. The mass of the seesaw is 35 kg. How far to the right of the central pivot must a second child of mass 40 kg sit if the seesaw is to be perfectly balanced.
A certain string just breaks while it is under 25 N of tension. A boy uses this string to whirl a 0.75-kg stone in a horizontal circle of radius 2.00 m. The boy continuously increases the speed of the stone. At around what speed would the string b..
A string requires a 186 N force in order to break. A 1.50 kg mass is tied to this string and whirled in a vertical circle with a radius of 1.90 m. What is the highest speed that this mass can be whirled without breaking the string.
Two boats start together and race across a 62-km-wide lake and back. Boat A goes across at 62 km/h and returns at 62 km/h. Boat B goes across at 31 km/h, and its crew, realizing how far behind it is getting, returns at 93 km/h.
A uniform spherical shell of mass 8.60kg with diameter 48 cm has four small masses of mass 2.00kg attached to its outer surface and equally spaced around it. This combination is spinning about an axis running through the center of the sphere and t..
What is the tension in (a) the nearer (relative to the person) cable and (b) the farther (relative to the person) cable.
How far from the dog will the suitcase land. A car accelerates uniformly (a = constant) from 34 meters/second up to 84 meters/second in 3.7 seconds. What is the acceleration of car in meters/second2.
Styrofoam has a density of 300 kg/m^3. What is the maximum mass that can hang without sinking from a 40cm diameter Styrofoam sphere in water? Assume the volume of the mass is negligible compared to that of the sphere.
At a certain time an object's position was observed to be 10 meters due west. 4 seconds later the position was observed to be 5 meters due east
drop a rock into a well. You hear the splash 2.40 s after you release the rock from rest. The speed of sound in air at the ambient temperature is 336 m/s. How far below the top of the well is the surface of the water?
