Two conductors having net charges of +15.0 µC and -15.0 µC have a potential difference of 15.0 V between them.
(a) Determine the capacitance of the system?
Describe its motion. (Will it slide forever at a constant velocity? Will it slide to a stop? Illustrate in what way will its energy changes be similar to that of a pendulum?)
A dipole is formed by point charges +3.8 micro Coulomb and -3.8 micro Coulomb placed on the axis at (0.45 m, 0) and (-0.45m, 0), respectively. At what positions on the axis does the potential have the value 7.7×105 V?
A 1 kg ball is attached to a 2 m long piece of very light string and suspended in such a way that it can freely swing and it passes just above the ground. completely describe the motion of the two masses after the 1 kg ball is released
A 320 kg rocket sled can be accelerated at a constant rate from rest to 1400 km/h in 2.0 s. What is the magnitude of the necessary net force.
Two identical pellet guns are fired simultaneously from the edge of a cliff. These guns impart an initial speed of 24.1 m/s to each pellet. Gun A is fired straight upward, with the pellet going up and then falling back down, eventually hitting the..
A 12- V battery causes a current of 0.40A through a resistor. A) what is its resistance B) how may joules of energy does the battery lose in minutes.
Coherent light with wavelength 591nm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3m from the slits. The first-order bright fringe is a distance of 4.84mm from the center of the central b..
The bunchberry flower has the fastest-moving parts ever seen in a plant.at first , the stamen are held by the petals in a bent position, storing elastic energy like a coiled spring.
Forces in a Three-Charge System Coulomb's law for the magnitude of the force between two particles with charges and separated by a distance is , where , and is the permittivity of free space.
Julie drives 100 mi to her Grandmother's house. On the way to Grandmother's, Julie drives half the distance at 25mph and the other half at 80. On her return trip, she drives half time at 25mph and half the time at 80 mph.
An unstretched spring has a length of 0.30 m. while the spring is stretched to a total length of 0.60 m, it supports traveling waves moving at 4.5 m/s. How fast would waves travel on this spring if it is stretched to 0.90 m.
A jeweler working with a heated 47 g gold ring should lower the ring's temperature to make it safe to handle. If the ring is initially at 99 degrees Celcius, what mass of water at 25 degrees Celcuis is needed to lower the ring's temperature to 38 ..
