Astudent wanted to obtain a very accurate value for the volume of a piece of steel. he filled a 100.0 cm3 graduated cylinder to the 50.0 cm3 mark with water. after he carefully dropped the steel into the cylinder, the water level rose to the 55.6 cm3 level. he reported the volume of the steel as 5.6 cm3. how could the student improve the reliability of his analysis?

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?
