A negative test charge −q is released from rest at a distance r away from a sphere of charge +Q, and a distance 2 r away from a sphere of charge +2Q. The charged spheres are fixed in place. System of charges arranged in a horizontal line. Test charge minus Q is in the middle position. Charge plus Q located a distance R to the left. Charge +2Q located a distance 2R to the right. In what direction does the test charge move immediately after being released?

The variables for this experiment include mass, volume and the materials in the various balls, as well as their densities. in part iii, you will be investigating the questionable baseball. use the drop-down menus to complete the sentences and identify the independent and dependent variables. in part iii, the independent variable, the one that is intentionally manipulated, is . in part iii, the dependent variable, the one that you measure the response in, is

Iwill give brainliest if you answer right : )

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid
