Potential difference between the two points-electric field
An electron moves through an electric field, and its speed drops from 2800 m/s to 1900 m/s. What's the potential difference between the two points at which the speed was measured?

Aspirin is a monoprotic acid; its formula isHC9H7O4. Acertain pain reliever was analyzed for aspirin by dissolving 0.250 g of it in water and titrating it with0.0300 M KOH solution. The titration required 29.40 mL of base.
Two point charges, +2.0 uC (micro Coulomb's) and -4.0 uC (micro Coulomb's), lie 0.45 m apart on the x-axis. Are there any points on the x-axis where the electric potential is zero? If so, find the point(s). If not, explain.
An element is diamagnetic if it has no unpaired electrons. Anelement is paramagnetic if it has unpaired electrons. If sulfur has unpaired electrons in the last p orbital (1s22s2 2p6 3s2 3p4), why is it diamagnetic instead of paramagnetic?
40-m long section of a horizontal steam pipe of 6-cm in outside diameter has a surface temperature of 170C and emissivity of 0.7. The pipe is in a room with air at 30C.
Ascorbic acid (vitamin C) is a diprotic acid of molecular weight176 g/mol. A sample of a vitamin supplement was analyzed bytitrating a 0.100 g sample dissolved in water with 0.020 M NaOH.
The heat transfer coefficient for convection between the chip and the coolant is 150 W/m2K. What is the cause of entropy production in this case?
A uniform electric field exists between two conducting plates separated by 1.9 mm. A dust grain with charge 65 nC (nano Coulomb's) between the plates feels a 22 N electric force. Find the potential difference between the plates.
