Plz ! dan took three samples of water from the creek behind his house once a month for the last six months. he tested the water and reported the results in the following data table. water quality indicator                                                test results dissolved oxygen- dissolved oxygen levels in the last three months decreased rapidly. fecal coliform- fecal coliform ranges from a low of 89 colonies per liter to 102 colonies per liter over the six-month period. nitrates- nitrate levels ranged from 6 to 7 mg/l. phosphates - phosphate levels were between 0.01 mg/l and 0.3 mg/l. ph the average ph was 6.9. turbidity - the water was clear in the first few months, but it became increasingly cloudy over time. which water-quality indicators would be of concern in this situation? explain your response. be sure to discuss any implications these water-quality indicators could have on the environment and human health.

The energy available as a result of the motion of a body is called energy. -potential -gravitational -kinetic -chemical

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.
