Water at 23.5°c has a density of 0.99742 g/ml. a 10.5 ml sample of water at 23.5°c, delivered from a pipet had a mass of 10.4532 grams as measured on an analytical balance.
(1) show the calculation of the actual volume as determined from this mass.
(2) show the calculation of the % error in volume delivered for this pipet. % error = (%u2502calculated value - delivered value%u2502/ delivered value) x 100

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
