yes the answer is cTHE TOTAL RESISTANCE DECREASES

yes the answer is a. Electrons are transfered to the stick,causing it to take on a negative charge.

yes the answer is a. negative charge.

yes the answer is a. 3 ohms RT= 9volts/3amps=3 V=9volts, and I=3amps:R=3ohms

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.

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.

yes the answer is d. 3v V2=(R2/(R1+R2) ) xVtotal

The electrons are transfered to the stick, causing it to take on a negative charge. Answer a.

Answer -Total resistance decreases.

When the attraction to the object approaches the the pithball there is an immediate repulsion is the answer.

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.

Piezoelectrictricity is caused by pressing or squeezing--- What?

quartz and Rochelle salt crystals

Metal wasn't one of the four basic" elements".

A CONDUCTOR IS MOVED THROUGH A MAGNETIC FIELD IS WHEN INDUCTION OCCURES.

YES 240- VOLT CIRCUIT IS ESSENTIAL

prevents electrical shocks

Coulomb is qualtity whereas an amper is rate of flow.

Yes the tv runs on alternating current(ac).

Watts is used in power expression.
