Which statement is true according to hooke's law?

a. as the force on a spring increases, the spring's length remains unchanged.

b. the distance a spring stretches has nothing to do with how much force is applied to it.

c. as the force on a spring increases, the distance it stretches increases.

d. as the force on a spring increases, the distance it stretches decreases.

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?
