How does the velocity of sound in air vary with the air temperature?

Question 2

An electron in an x-ray machine is accelerated through a potential difference of 1.00  104 V before it hits the target. What is the kinetic energy of the electron in electron volts?
  1.1.00  104 eV
  2.1.60  10-15 eV
  3.1.60  10-22 eV
  4.6.25  1022 eV
  5.1.60  10-19 eV
