Dr. alvarez wanted to see if he had discovered a new element, so he analyzed his new element and performed an experiment to determine the element's density, melting point, and boiling point. then, he repeated his experiment four more times before reporting his results in a scientific journal. dr. casey read dr. alvarez's report. wanting to verify dr. alvarez's data, dr. casey repeated dr. alvarez's experiment three times, compared his results with dr. alvarez's results, and reported his own results in a scientific journal. which of the following is an example of replication? a. when dr. casey reported his results in a scientific journal b. when dr. casey repeated dr. alvarez's experiment c. when dr. casey repeated his own experiment three times d. when dr. alvarez repeated his own experiment four times

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?
