Question

A balloon will slick to a wooden w all if the balloon is charged (A) negatively (B) positively. C. either positively or negatively. None of the above choices are correct. Three resistors, I-ohm. 2-ohm, and 3- ohm are connected in parallel. If they were connected in series instead their equivalent resistance would be 7 times as great. 9 times as great. 11 times as great. 13 times as great. None of the above choices are correct. Compared to the huge force that attracts an iron tack to a strong magnet, the force that the lack exerts on the magnet is relatively small. equally huge. More information is needed. Which force field can increase a moving electron's speed? only an electric field. Only a magnetic field

Explanation / Answer

According to the chegg guidelines I am allowed to answer only 1 question at a time.

Question a) Option c) is correct either positively or negatively. ===========OPTION C) ==ANSWER)

Question b) R(p) = ( 1/1 + 1/2 + 1/3 ) ^ -1 = ( 11/6 ) ohms

R(s)= 1 + 2 + 3 = 6 ohms

So the correct option is OPTION C) 11 TIMES AS GREAT ================OPTION C) ---ANSWER)
