Two large parallel plates stand side by side with a distance of 2.10 cm between them. The plates hold equal and opposite uniformely distributed charges. An electron starts in the region between the plates next to the left hand plate and has an initial velocity of 1.63 X 10^4 m/s towards the right. It travel across the gap and slams into the right hand plate. Its speed on reaching the right hand plate is 4.15 X 10^4 m/s.
A) Find the acceleration of the electron
B) Find the magnitude and direction of the electric field in the region between the plates
C) Which plate is positively charged and which is negatively charged?
D) If the plates are square with an edge length of 25.4 cm, determine the charge on each.
A quantity of a gas has an absolute pressure of 400 kPa and an absolute temperature of 110 degrees kelvin. When the temperature of the gas is raised to 235 degrees kelvin, illustrate what is the new pressure of the gas?
Bob has just finished climbing a sheer cliff above a beach, and wants to figure out how high he climbed. All he has to use, however, is a baseball, a stopwatch, and a friend on the ground below with a long measuring tape. Bob is a pitcher, and kno..

An insulated Thermos contains 123 cm3 of hot coffee at 73 °C. You put a 12.0 g ice cube at its melting point to cool coffee. By how various degrees has your coffee cooled one time the ice has melted and equilibrium is reached? Treat the coffee as tho..
A 1000-kilogram race car is traveling at 60 m/s around a curved section of track that has a radius of 300 m. What is the car's centripetal acceleration? What is the centripetal force that acts on the car?
Two large, parallel, conducting plates are 26cm apart and have charges of equal magnitude and opposite sign on their facing surfaces. An electrostatic force of 2.8 x10-15 N acts on an electron placed anywhere between two plates.
The hydraulic cylinder is subjected to 3 forces. An 8kN force is exerted on cylinder at B that is parallel to the cylinder and points from B towards C. The link AC exerts the force at C that is parallel to the line from A to C. The link CD exerts ..
When a certain spring is stretched by an amount x, it produces a restoring force of F(x) = ax=bx^2, where a and b are constants. How much work is done through an external force in stretching the spring by an amount D from its equilibrium length.
A motorcycle cop, parked at the side of a highway reading a magazine, is passed by a woman in a red Ferrari 308 GTS doing 90.0 km/h. After a few attempts to get his cycle started, the officer roars off 2.00 s later.
