Physics
A −5 × 10−6 C charge is brought from a very distant point by an external force and placed at the origin. Calculate the magnitude of the electric force on this charge. Answer in units of N

Physics
Charge 2 × 10−18 C is on the y axis a distance 4 m from the origin and charge 9 × 10−18 C is on the x axis a distance d from the origin. What is the value of d for which the x component of the force on 9 × 10−18 C is the greatest? The Coulom...

Chemistry
No, I did the same online quiz and CH3NH3+ is not correct. Weakest aicd will be least reactive, that means it will have larger concentration, in this CH3NH3+ and NH3OH+ are functioning as acids, CH3NH3+ is 95%. so the strongest acid should be NH3OH+
