The specific heats of aluminum and iron are 0.214 and 0.107 calories per gram degrees Celsius [cal/(g degrees Upper C)] respectively. If we add the same amount of energy to a cube of each material (of the same mass) and find that the temperature of the aluminum increases by 28 degrees Fahrenheit [degrees Upper F], how much will the iron temperature increase in degrees Fahrenheit [degrees Upper F]?

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?
