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
