Scientific experiments are specially designed to test explanations for an observed phenomenon. a student decides to conduct an experiment to determine the effect that the amount of time spent in the sunlight has on the overall growth of a plant. the student will conduct the experiment using two identical plants that will only spend different amounts of time in the sunlight. all other aspects needed for growth will remain identical for each. in the experiment described, what would the amount of water given to each plant be considered?

Control variable

Explanation:

There are 3 types of variables in this kind of study:

In the experiment, the dependent variables are those used to indicate the growth rate of plants such as length of shoot, number of leaves etc. The independent variable is light.

The amount of water supplied to each plant must be the same because water has effect on the growth of plant.

Hence, water is considered a control variable.

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

f=ma newton

f=100x2.5=250n
