Question

10 sanjay is performing an experiment to test the effects of weight on a pendulum. he identifies the variables as the weight of the pendulum, the length of the string, the height that he pulls the weight back, and the time it takes for the pendulum to stop moving. identify the independent variable that sanjay intends to test.
o weight of the pendulum
o time for the pendulum to stop
o length of string
o height of the pullback

Explanation:

In an experiment to test the effect of weight on a pendulum, the independent variable is what the experimenter changes. Here, Sanjay intends to test the effect of the weight of the pendulum, so the weight is the variable he will manipulate. Other factors like length of string and height of pull - back are controlled variables if he wants to isolate the effect of weight, and the time it takes for the pendulum to stop moving is the dependent variable (the outcome that is measured).

Answer:

weight of the pendulum
