In an experiment, the hypothesis is if the wavelength of the light shining on a plant is shortened, the rate of photosynthesis is slowed down. if this experiment is performed, the dependent variable
cannot be determined
will be the rate of photosynthesis
will be the plant on which the light is shining
will be the wavelength of the light

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
