What is the total resistance of the circuit? (must include unit - ohms)

4 ohms

Explanation:

R1=24 ohms

R2=8 ohms

R3=12 ohms

Let total resistance Be R

It is a parallel connection

1/R=1/R1 + 1/R2 + 1/R3

1/R=1/24 + 1/8 + 1/12

1/R=(1+3+2)/24

1/R=6/24

Cross multiply

6R=24

Divide both sides by 6

6R/6=24/6

R=4

Total resistance =4 ohms

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

i don't understand. explain it clearly
