Which of the following is the best hypothesis for this experiment? (remember that the variable we are going to manipulate is the if part of a hypothesis and the variable we hope will respond and we will measure is the then part of a hypothesis.) question 1 options: a. if i increase the pressure outside of an air filled balloon, then the balloon will become smaller b. if i increase the temperature of the air in a balloon, then the balloon will become larger. c. if i increase the size inside of a balloon, then the air in the balloon will become hotter.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
