Two resistanceless rails rest 24 cm apart on a 4.0 ∘ ramp. They are joined at the bottom by a 0.70 Ω resistor. At the top a copper bar of mass 0.080 kg (ignore its resistance) is laid across the rails. The whole apparatus is immersed in a vertical 0.50 T field. Part A What is the terminal (steady) velocity of the bar as it slides frictionlessly down the rails

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
