The chart shows the movement of a ball after several seconds. A 2-column table with 4 rows. The first column labeled A has entries 0, 4, 8, 12, 16. The second column labeled B has entries 0, 2.5, 6, 8, 10. Column A is on the x-axis, and Column B is on the y-axis. Which titles should replace A and B? Column A should be “Time,” and Column B should be “Position.” Column A should be “Position,” and Column B should be “Time.” Column A should be “Velocity,” and Column B should be “Speed.” Column A should be “Speed,” and Column B should be “Velocity.”

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask

Aradio signal from a gps satellite take only about 0.067 seconds to reach a gps reciever. if the speed of light is about 300,000km/s, then approximately how far away is the reciever from from the satellite?
