yes the answer is B. Electrons become charged when a charged object comes close to it, causing it to become charged.The movement is moved.
When the attraction to the object approaches the the pithball there is an immediate repulsion is the answer.
Answer -Total resistance decreases.
The electrons are transfered to the stick, causing it to take on a negative charge. Answer a.
yes the answer is d. 3v V2=(R2/(R1+R2) ) xVtotal
The choice of answer is either a. 6v b.5v c.4v d.3v so The battery voltage change is 9volts and the new voltage across light bulb #2 is 3v.
There was a chart, it needs the information changed by only piece : change the battery voltage to 9 volts.Once you have redone each of the tables, what is the new voltage across light bulb #2? I have 5V as an answer.
yes the answer is a. 3 ohms RT= 9volts/3amps=3 V=9volts, and I=3amps:R=3ohms
yes the answer is a. negative charge.
yes the answer is a. Electrons are transfered to the stick,causing it to take on a negative charge.
yes the answer is cTHE TOTAL RESISTANCE DECREASES
