Amy wants to measure the thickness of a single sheet of A4 size paper. She used a ruler to measure the thickness of a ream of paper with 100 sheets as shown in the figure. Section of ruler is shown next to a ream of paper. The markings on the ruler are from zero to two centimeters. There are two small markings, one is between zero and one and the other is between one and two. The thickness of the ream of paper starts at zero and goes to the small marking which is exactly between zero and one.

Which of these is the most accurate thickness of a single sheet of paper?

0.001 cm
0.005 cm
0.01 cm
0.05 cm

If two objects at different te, peraure are in contact with each other what happens to their temperature

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
