Homework Statement Homework EquationsThe Attempt at a Solution Vt=30V It=4.3A Rt=7Ω V1=12.9V V2=2.15V V3=2.15V V4=4.3V V5=12.9V VA=4.3V VB=4.3V I1=4.3A I2=2.15A I3=2.15A I4=2.15A I5=4.3A IA=2.15A IB=4.3A R1=3Ω R2=1Ω R3=1Ω R4=2Ω R5=3Ω RA=2Ω RB=1Ω Did I break down the problem correctly...

i am in 10th grade and i recently just learned this

yes, i understand that but i don't get what makes a circuit a series or parallel.

is it the opposite?

3, 4, and 5 are parallel to each other. does that mean that 1 and 2 are series?

resistor 3 and when it leaves 3, it goes to 2? and when it leaves 2, it goes to 1?

oh to resistor 4?

back to resistor 1?

i'm not sure how to tell that apart.

is 2 and 4 in a parallel circuit as well as 3 and 5?

Homework Statement Homework Equations IR=V series circuit Vt = V1 + V2 + V3... It = I1 = I2 = I3... Rt = R1 + R2 + R3... parallel circuit Vt = V1 = V2 = V3... It = I1 + I2 + I3... Rt = 1/R1 + 1/R2 + 1/R3... The Attempt at a Solution i honestly have no idea where to start. may someone pls...

oh okay so the side that the magnet attracts north on a compass is the south pole of the magnet?

that the part of the magnet that attracts north is also the north pole of the magnet

when a magnet attracts the north end of a compass, what does that mean?

Homework Statement A child 1.52 meters tall pulled a 2.54 kg toy car for 10 meters. The car has a string attached to it, and when pulled creates a 25 degree angle from the horizon. If the string has a force of 123 N on it while being pulled, how much work did the child do? Homework Equations...
