    Ethanol Production: Is My Yield Limited to 13%?

    So for an experiment I must make ethanol from sugar using yeast. I've read that yeast dies at around 13% concentration of alcohol. So does that mean that my experiment is limited to a 13% yield?

    Upward Acceleration of an Object

    well so assuming this is all theoretical you would assume no air resistance. However for the thrust you will need to account Fg on the object because the value put in has to be fnet=ma. So you would need mass for this or else you can't really solve for upwards acceleration thus you can't sub in...

    How Do Hearing Aids Amplify and Filter Sound?

    Well we have to describe how hearing aids amplify sound. I need a understanding of the physics behind it how its works, no stuff about transistors and how its built. So like how does it amplify sound. ie change amplitude, wave length. etc Also how they remove unnecessary noises. If you can...

    Air drag and acceleration (not gravity)

    4.96 seconds is the time it took for velocity to be 0, ... reach maximum height

    Air drag and acceleration (not gravity)

    In physics class we made a rocket and test fired it. Now we are given the thrust and we found out the max height of the rocket and the time of flight. Max Height = 76m Time of thrust/ upward acceleration = .8s Time of flight with only gravity acting until velocity is 0 . = 4.96s (not...
