Why does an investigator change the value of a variable parameter during an investigation?

Hi!

Usually you have two types of variables, the independents (parameters that you can change and modify, such as the time you left a potato in a hot oven) And dependent variables ( such as the temperature of said potato when you took it out of the oven).

The parameters in a investigation are independent variables, and you want to change them to see how the changes impact in the dependent variables, in order to describe these changes.

150.6

all i did was i multiplied 5.02 by 30

(53.5 - 18.4) m.

step-by-step explanation:

after undergoing a displacement of 18.4m, the initial position was (53.5 - 18.4) m if an object has a final position of 53.5.
