the answer of question4 is (B)can you give me some detail explanation??

Questions 3 and 4 refer to the following material. An experiment is performed in which a cube is suspended from a spring scale, The cube is lowered into a beaker of water. egsxx y reading Fs' = Fg) Fb eg4 kx = (mg) = ex Tsubg 3. If the independent variable is the distance the cube is lowered, and the dependent variable is the reading on the scale, what will a graph of the data show? PX = SPY (A) The graph will show a positive correlation and be linear. (B) The graph will show a negative correlation and be linear. (C) The graph will show a positive correlation, but will be nonlinear. V sub (D) The graph will show a negative correlation, but will be nonlinear. 1 20 2 V sub 2 linear If the cube is replaced with a sphere and the same experiment is performed, which correctly describes the graph of the variables for the new experiment? (A) The graph will be the same for both experiments because both experiments have the same independent and dependent variables. (B) The graph will be different for both experiments because both experiments have the same independent and dependent variables. (CY The graph will be different for both experiments because they have different independent (B ) variables but the same dependent variable. The graph will be different for both experiments because they have different dependent variables but the same independent variable
