In an experiment to measure the speed of a bee as it flies, a small ball is hung by a thread. When the bee lands on the ball, the ball swings upwards. Scientists record a video of the bee as it lands and analyse the video to determine the height to which the ball swings. mass of bee = 0.25 g; mass of ball = 0.45 g

The ball with the bee attached to it is found to rise to a vertical height hof 6.0 cm. Calculate its increase in gravitational potential energy.

Why should the scientific method be used to answer a question? a. it provides a way to test an idea without any bias. b. it provides a way to test a hypothesis. c. it provides a way to ensure all hypotheses are proven correct. d. it provides a way to quickly turn a hypothesis into a scientific theory.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
