All of the following statements describe how rubbing one object on another creates static electricity except: a. rubbing converts neutrons to protons, increasing the charge. b. charge is transferred from one object to the other. c. the electrons get ripped off one object and held by the other. d. rubbing allows the object that has the greater electron attraction to take them.

A. Rubbing converts neutrons to protons, increasing the charge

Explanation:

Rubbing two objects creates static electricity. It is also known as charging by friction.  When two objects having different electron affinity are rubbed together, the one with greater electron attraction rips off the electrons from other object. In this way charge is transferred from one to another. The one losing the electrons becomes positively charged and the one gaining the electrons becomes negatively charged. Neutrons do not convert to protons. Thus, this is a wrong statement.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
