The charge per unit length on a long, straight filament is-92.0 μc/m. (a) find the electric field 10.0 cm from the filament, where distances are measured perpendicular to the length of the filament. (take radially inward toward the filament as the positive direction. mn/c (b) find the electric field 46.5 cm from the filament, where distances are measured perpendicular to the length of the filament. mn/c (c) find the electric field 130 cm from the filament, where distances are measured perpendicular to the length of the filament. mn/c

Complete the sentence to describe the law of conservation of energy. the law of conservation of energy states that energy cannot be created

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?

The applied force of 3 washers will increase the applied force on the car to n.
