An electron in an oscilloscope is accelerated as a result of the potential difference between the cathode and anode. The electron has negligible initial speed and a final speed of 2.40 107 m/s. Find the voltage drop from cathode to anode.
A horizontal beam of electrons initially moving at 3.4 107 m/s is deflected vertically by the vertical electric field between oppositely charged parallel plates.
What was the initial negative charge on one of the spheres, and what was the initial positive charge on the other?(Hint: Use charge conservation and solve for one of the initial charges. You will end up with a quadratic equation. The solutions giv..
A rectangular container measuring 23 cm 51 cm 65 cm is filled with water. What is the mass of this volume of water in kilograms and grams.
What is the frequency of up and down oscillations of the wheel? Regard wheel as a mass on one end of a spring and regard the body of the car as a fixed support for the other end of the spring.
what is the needed magnitude of the minimum acceleration.
The arm of a crane at a construction site is 14.4 m long, and it makes an angle of 40° with the horizontal. Assume that the upmost load the crane can handle is limited by the amount of torque the load produces at the base of the arm.
At rest when constructed, the ring is set rotating about its axis so that the people inside experience effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the r..
What must the charge (sign and magnitude) of a particle of mass 1.44g be for it to remain stationary when placed in a downward directed electric field of magnitude 660 N/C.
A point charge q1 = -2.3 x 10^ -6 C is located at the origin of a co-ordinate system. Another point charge q2 = 6.3 x 10^-6 C is located along the x-axis at a distance x2 = 6.1 cm from q1. 1) What is F12,x, the value of the x-component of the forc..
A tow truck pulls a car 5.2 km along a horizontal roadway using a cable having a tension of 790.
On a day of 30 degrees celcius, full sun, how hot would a granite paver get? Will a dark grey one get much hotter than an off white coloured one.
