Next, she places all four plants on the same windowsill, so they all receive the same amount of light each day. plant 1 stays in
the same position throughout the experiment. plant 2 is turned 180 degrees every 12 hours. plant 3 is turned 180 degrees every
24 hours. plant 4 is turned 180 degrees every 48 hours.
mrs. fairchild monitors the plants daily. she counts the number of leaves on each side of the plant, and she uses a protractor to
measure how far each plant is leaning away from the stick.
what is the test variable (independent variable) in the experiment?
pls

(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?
