When analyzing related data variables, how can one tell which one is the independent variable and which one is the dependent var
1 answer:
Answer:
Dependent and independent Variable.
Step-by-step explanation:
Dependent and independent Variable.
- The two variables in an experiment are independent and dependent variable.
- Usually, the dependent variable is denoted by y and the independent variable a re denoted by
- The dependent variable depends on independent variable in an experiment and thus cannot be controlled.
- On the other hand we can change or control the independent variables to test effect on dependent variable.
- As the independent variable are changed, we observe corresponding changes in the dependent variable.
- Example: Let money spend be the dependent variable. It depends on an independent variable of shopping. We may control or change or shopping habits to see the changes in the money spent. Money spent totally depends in the amount f shopping done.

Answer:
23.7m
Step-by-step explanation:
Given parameters:
Time taken = 2.2s
Acceleration due to gravity = 10m/s
Unknown:
Depth of the well = ?
Solution:
To solve this problem, we simply apply one of the motion equations;
S = ut + gt²
where S = depth of the well
u = initial velocity
t = time taken
g = acceleration due to gravity
Input the parameters and solve for S;
Note initial velocity = 0;
S = x 9.8 x 2.2²
S = 23.7m
