Sam and Loretta saw a cool experiment on TV and wanted to try it on their own. First, they poured sand into a plastic cup until it was half full. Next, they used a thermometer to take the sand’s temperature. They then taped a cup upside down on top of the cup with sand in it. Sam and Loretta took turns shaking the cup. They shook it 100 times, un-taped it, and took the sand’s temperature. The temperature was 10 degrees C. They re-taped it, shook it 500 times, un-taped it and took the sand’s temperature. The temperature was 15 degrees C. They re-taped it, shook it 1000 times and then un-taped it and took the sand’s temperature. The temperature was 20 degrees C. 1. What was the Independent Variable for this experiment?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
