A bar magnet and a second object are hung from metal rods. The diagram below shows what happens when both objects are released. At left, rectangular box with 2 black lines running straight down from it, each to a horizontal bar magnet with the left magnet labeled N to the left and S to the right and the right magnet unlabeled. There is a gap between the magnets. At right, a rectangular box with 2 black lines running down from it, each to a horizontal bar magnet with the left magnet labeled N to the left and S to the right and the right magnet unlabeled. There is a gap between the magnets. The left magnet hangs to the left. The right magnet hangs to the right. Which best describes the object on the right? an iron bar a steel bar a bar magnet with its north pole on the left a bar magnet with its south pole on the left

How have the greenhouse gasses increased from the year 2000 to 2018

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]

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.
