Fluorine-18 undergoes positron emission as shown:
18 F→ 4X+ AB
Enter the appropriate values for A and Z and the chemical symbol for

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
