Levi decides to examine the effect of fertilizer on the growth of tomato plants. he chooses four plants for his experiment and applies varying amounts of fertilizer to three of them. he does not apply fertilizer to one plant.
over a 15-day period, the plants receive fertilizer on days 1, 4, 7, 10, and 13. levi measures the height of all of his plants with a meterstick on days 3, 6, 9, 12, and 15. he also makes sure to hold all experimental factors constant except for the fertilizer.
what is the dependent variable in levi's experiment on tomato plants?
the measurements of plant height
the days plant height was measured
the amount of fertilizer given to the plants
the days fertilizer was applied

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
