The electric field in an xy plane produced by a positively charged particle is 4.94(6.9i + 4.4j)N/C at the point (5.9, 5.8) cm and 131i N/C at point (2.8, 0)cm. What are (in cm) the
(a) x and
(b) y coordinates of the particle?
(c) What is the charge (in Coulombs) of the particle?
Two charges A and B are fixed in place, at different distances from a certain spot. At this spot the potentials due to the two charges are equal, Calculate the ratio qB/qA of the charges
The density of water is 1000kg/m^3 or 8.33lbm/gallon, the mass flow rate is 494838.83 kg/s and goes through a turbine generator that has 0.80 efficiency
A 14 liter tank of helium is at a pressure of 164 kPa at a temperature of 0 C, What is the speed of the helium atoms in the tank at this new volume, How many moles of helium are there in the tank
A 600 turn solenoid, 25 cm long, has a diameter of 2.8 cm. A 10 turn coil is wound tightly around the center of the solenoid. If the current in the solenoid increases uniformly from 0 to 5.0 A in 0.48 s, what would be the induced emf magnitude in the..
A ball is shot from the ground into the air. At a height of 10.60 m, the velocity is observed to be v = (8.60 m/s) i + (6.50 m/s) j
A professor's office door is 0.9 wide, 2.2 high, 4.2 thick; has a mass of 23 , and pivots on frictionless hinges. A "door closer" is attached to door and the top of the door frame. while the door is open and at rest, the door closer exerts a torqu..
A thin metallic spherical shell of radius 41.6 cm has a total charge of 8.05 ?C uniformly distributed on it. At the center of the shell is placed a point charge of 2.83 C. What is the electric field at a distance of 23.9 cm from the center of the ..
A rocket is launched at an angle of 52° above the horizontal with an initial speed of 103 m/s. The rocket moves for 3s along its initial line of motion with an acceleration of 32 m/s2. At this time, its engines fail and the rocket proceeds to move..
An object falls because of gravity at a rate of -9.80 m/s2 (- sign is indicative of a downward direction) for 10.00 Seconds. If it starts from rest (vo= 0) and its position starts from do= 0.0, where is it 10.00 Seconds later.
Two nonconservative forces are present: friction does -2.00 104 J of work on the car, and a chain mechanism does +3.00 104 J of work to help the car up a long climb. Illustrate what is the change in the car's kinetic energy, ΔKE = KEf - KE0, fro..
