Homework Answers
normally conductors are charges by the principle of induction but for insulators, induction is not possible so we need to create charge by friction.
so when a insulator is rubbed against another material, then electrons present will gain energy and will leave the atom so one material loses electrons and other gain it . this is how insulator can be charged.

How do you calculate the net charge of a molecule? For example what would the net charge of this molecule in the stomach at a ph of 1.8 be? The answer is +1 but why? I understand that the asp molecule is negatively charged so why is the answer +1? I am referencing to Lys his arg being positively charged Asp and gluare negatively charges and Cys and tyr neutral

D Question 12 1 pts How can a charged object attract an uncharged object made of non-conducting material? The uncharged object must somehow gain a like charge. Attraction of an insulator is not possible. The charges in the uncharged object can become polarized. O The uncharged object must somehow gain an unlike charge.
