Keesha did an experiment to study the rate of photosynthesis in the water plant elodea. she placed a piece of elodea in a beaker of water and set the beaker 10 centimeters (cm) from a light source. keesha counted the bubbles released from the plant every minute for five minutes (min). she repeated the process two more times. first, she moved the light to 20 cm from the beaker, and then she moved the light to 30 cm from the beaker. what is the outcome variable (dependent variable) in this experiment? what is the key phrase that tells you what you are looking for?

What is the outcome variable in this experiment?

The dependent variable which is the outcome of bubbles produced.

Keesha did an experiment to study the rate of photosynthesis in the water plant Elodea.

My guess would be that since we initially know what the experiment is for, the key phrase is:

Keesha counted the bubbles released from the plant every minute for five minutes (min). She repeated the process two more times.

answer: 0 meters/second^2

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
