The pressure in a vessel containing methane and water at 70°C is 10 atm. At the given temperature the Henryâ??s law constant for methane is 6.66 x 104 atm/mole fraction. Estimate the mole fraction of methane in the liquid.
A proton accelerates from rest in a uniform electric field of 675 N/C. At some later time, its speed is 1.35 106 m/s. (a) Find the magnitude of the acceleration of the proton.
A 4.5kg dog stands on an 18 kg flatboat at distance D = 6.10m from the shore. It walks 2.4 m along the boat toward shore and then stops. Assuming no friction between the boat and the water, find how far the dog is then from the shore.
Two charges, qA and qB, are divided by a distance, d, and exert a force, F, on each other. Analyze Coulomb's law and answer the following questions.
Determine the magnitude (in mN) and direction (relative to the negative x-axis in degrees) of the force acting on a particle with charge q3 = +11 nC placed at the origin.
Two sound speakers separated by a distance of 3-meters, are driven in phase by same audio amplifier. A listener sits directly in front of one speaker at a distance of 4 meters from it so that listener and speakers form a right triangle.
The velocity component of the particle at x = 8.0 m is 2.8 m/s. Illustrate what is the acceleration component during this time interval?
If the proton is fired at a speed of 3.0×107m/s , what is its closest approach to the surface of the nucleus? Assume the nucleus remains at rest
define How much charge is on each plate.
A converging lens has a focal length of f = 22.0 cm. An object is placed 41.0 cm from the lens. Find the size of the image in cm if the object has a height of 4 cm. express answer with one decimal place.
What distance does baseball move before its release
A professor's office door is 0.90 wide, 2.00 high, 4.00 thick; has a mass of 30, and pivots on frictionless hinges. A "door closer" is attached to door and the top of the door frame. When the door is open and at rest, the door closer exerts the torqu..
A 23 gram bullet traveling 230m/s penetrates a 2kg block of wood and emerge clearly at 170m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after bullet emerges.
