1 angstrom = 10^-8 cm
6.5 x 10-4 cm = 65 000 x 10-8 cm = 65 000 angstroms
answer 65 000 angstroms
District of Columbia, and Puerto Rico require occupational therapists and occupational therapy assistants to be licensed. States have similar, but not identical requirements and procedures for obtaining a license. For specific state licensure requirements always consult the state occupational therapy regulatory agency. See the State Regulatory Contact List for information on who to contact in your state.
To obtain a license you will need to:
Graduate from an accredited OT or OTA educational program.
Complete your fieldwork requirements.
Apply for and Pass the NBCOT® Certification Examination. For additional information regarding the examination, including ordering Score Transfers and/or State Confirmation Notices, refer to the NBCOT Web site.
Apply for a license and pay a fee for each state/jurisdiction in which you wish to practice or hold a license.
Many, but not all states allow practitioners to practice on a temporary license or limited permit while waiting to take or receive the results of the certification exam. If you fail the exam, you may not be able to continue to practice. Each state OT regulatory agency should be consulted for specific requirements.

Answer: Electron affinity increases on moving across a period.
Explanation:
When an electron is added to a neutral atom to convert it into a negative ion, the tendency is known as electron affinity.
Smaller is the size of an atom more readily an electron will be gained by it because of strong force of attraction exerted by its nucleus towards the electron.
As moving from left to right in a period, more and more electrons get added up in the same shell and the attraction between the last electron and nucleus increases, which results in the shrinkage of size of an atom.
Also, size of atoms decreases from left to right in a periodic table, thus tendency to gain electrons will also increase on moving from left to right.
So, on moving across a period, there will be an increase in electron affinity.
