Acar is traveling up a hill that is inclined at an angle of θ above the horizontal. (d) what is the algebraic expression for the ratio of the magnitude of the normal force to the weight of the car? express your answer in terms of the angle θ at which the hill is inclined. ratio =

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
