They both experience the same impact force however the fly will experience a greater acceleration

Phys
V = (f)* (wavelength) 200m/s = 100hz * Wavelength solve for wavelength then multiply by 3 dont forget to use the units for each variable like he gave us in class i.e. frequency = vibration/time wavelength = distance/vibration velocity = distance/time

Physics
I know for sure that the answer is not B or C since the volume increases and the temperature increases, however i am having a hard time understanding the definition of an adiabatic process and how to determine if there is any heat lost to the atmosphere. I am pretty sure the a...
