An electron of mass 9.11×10?31kg leaves one end of a TV picture tube with zero initial speed and travels in a straight line to the accelerating grid, which is a distance 1.30cm away. It reaches the grid with a speed of 2.50×106m/s . The accelerating force is constant.
Find the acceleration.
Find the time to reach the grid.
Find the net force. (You can ignore the gravitational force on the electron).
A vertical containery with base area measuring 14.0 cm by 17.0 cm is being filled with identical pieces of candy, each witha volume of 46.0 mm3 and a mass of 0.0208 g.
What is the potential difference between two points that are 0.800 m and 3.75 m from a proton? What is the diameter of the 1.80 V eqipotential surface
A train is traveling up a 3.3 incline at a speed of 3 when the last car breaks free and begins to coast without friction. How long does it take for the last car to come to rest momentarily? How far did the last car travel before momentarily coming..
The potential at location A is 481 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 878 V, and when released from rest from this spot, the particle arrives at B wit..
These two isotopes are singly ionized (+e) and each is given a speed of 6.00 x105 m/s.
A bus is traveling up a hill at a speed of 34m/s. The hill is 23 degrees relative to horizontal and the coefficient of static friction between the bus's tires and the road is 0.6. What is the car's minimum breaking distance?
