Part 1: What is your Reaction Time? The average human reaction time for a visual stimulus is estimated to be about one-fourth of a second. Let's
see if your reaction time is quicker than that of the average person!
Using only a ruler, the acceleration due to gravity on earth, and your constant acceleration kinematics
equations, devise an experiment that allows you to determine your reaction time.
Questions to consider:
1. What quantity can you measure with a ruler?
2. What is the acceleration due to gravity on earth?
3. How do these two things relate to time, using constant acceleration kinematics equations?

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 2 options: the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the cold balloon expands and rises. the warm balloon shrinks and sinks. the warm balloon expands and rises. the cold balloon shrinks and sinks.
