An electron moving horizontally at 3.15 x 106 m/s enters a vertical magnetic field. The magnetic field exerts a force on the electron of magnitude 5.73 x 10-12 N. Find the magnitude of the magnetic field in tesla (T).
Suppose a 76 kg person hangs vertically from a nylon rope. What radius must the rope have if its fractional increase in length is to be the similar as that of the spider's thread.
describes the net gravitational force on the particle due to the shell? zero if the particle is at the center of the shell but nonzero at other locations within the hollow zero for any location of the particle within the hollow.
A loudspeaker of mass 24.0 {rm kg} is suspended a distance of h = 1.40 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.70 {rm m}.
Two stationary positive point charges, charge 1 of magnitude 3.45 nC and charge 2 of magnitude 1.50 nC, are separated by a distance of 52 cm. An electron is released from rest at the point midway between the two charges, and it moves along the lin..

A water molecule can vibrate in various ways, but the easiest kind of vibration to excite is the "flexing" mode in which the hydrogen atoms move toward and away from each other by HO bonds do not stretch.
With brakes fully applied, a 1430kg car decelerates from a speed of 74km/hr. What is the work done by the braking force in bringing car to a stop.
Explain why should the Bryson Corporation act ethically in this situation? Illustrate what are the potentially negative representations of acting unethically?
As you sit facing your computer screen, electrons are directed from a source at the back of the computer toward you and are deflected by a magnetic field. Which direction must the magnetic field be oriented in order to direct the electrons to the ..
