Is anyone taking Integrated Physics and Chemistry (2014) on switched on schoolhouse if so please answer I have a question ab the class!! Thanks

In which of these cases are the two wave points considered to be in phase with each other?

Given that 1 mi = 1760 yd, determine what conver- sion factor is appropriate to convert 1849 yd to miles; to convert 2.781 mi to yards.

In the millikan oil drop experiment they determined that every drop had a charge which was a while number multiple of -1.60x10^-19. if a drop has a total charge of -9.60x10^-19 then how many excess electrons are contained within the drop?
