in an investigation, a student attaches one end of a spring scale to a 2 - kilogram block. the block is initially at rest on the level surface of a desk as shown. the student pulls on the other end of the spring scale. the student observes that a minimum force of 10 newtons is needed to start the block moving along the surface.\nthe student repeats the procedure with a 1 - kilogram block and a 4 - kilogram block. the blocks are all made of the same material and the procedure is repeated on the same surface. use the menus to complete the statement about the variables in the investigation.\nin this investigation, the independent variable is the \nthe dependent variable is the

Answer

Answer:

Independent variable: mass of the block Dependent variable: minimum force needed to start the block moving

Explanation:

Step1: Define independent variable

The variable that is changed by the experimenter. Here, the student changes the mass of the block (2 - kg, 1 - kg, 4 - kg).

Step2: Define dependent variable

The variable that is measured and depends on the independent variable. Here, the minimum force needed to start the block moving is measured for different block - masses.
