**CHEMISTRY**

You subtract the moles of NaoH from the moles of HCl to determine the excess moles left, which decides the pH. To find pH, pH= -log(concent. of H+) or ( concen. of OH-) If NaOH is more than HCl, you get find pH by subtracting the pOH you get from the above formula from 14.

**physics**

Devon : a = F / m Effective F = upward force - downward force (weight) = 11- 15.5 = 4.5 downward a = 4.5/ (15.5/9.8) = 2.8 m/s downwards. (I'm pretty sure anyway)

**physics**

Yes if the upward force is less than gravitythen the acceleration would be downward, but it wouldn't be negative as it's not a deacceleration. :)
