Two 1.90-cm-diameter disks spaced 2.10mmapart form a parallel-plate capacitor. The electric field between the disks is 5.10×105V/m . An electron is launched from the negative plate. It strikes the positive plate at a speed of 2.50×107m/s . What was the electron's speed as it left the negative plate?
Over a certain region of space, the electric potential is given by: V = 3x^2 - 2xy + xyz, Find the expressions for the x, y, and z components of the electric field over this region

A diver 50 m deep in 10 degrees Celsius fresh water exhales a 1.2 cm diameter bubble. What is the bubble's diameter just as it reaches the surface of the lake, where the water temperature is 35 degrees Celsius? Suppose that the air bubble is always i..
How many kilograms of water at 100.0 C could be converted to steam by the addition of 1.13 x 10^7 joules of thermal energy.
The mass of a roller-coaster car, including its passengers, is 495kg. Its speed at the bottom of the track in the figure below is 17.00 m/s. The radius of this section of track is r1 = 26 m. Find the force that a seat in the roller-coaster car exerts..
A 2.75-gram air inflated balloon is given an excess negative charge, q1 = -3.00 × 10-8 C, by rubbing it with a blanket. It is found that a charged rod can be held above the balloon at a distance of d = 5.20 cm to make the balloon float. In order f..
The acceleration of gravity is 9.81 m/s^2. Assuming that air resistance is simply a constant 96 N force on the person during the fall, identify the person's velocity just before hitting the net. Answer in units of m/s.
What is the net entropy change
