Water Rocket Lab Kinematics: Motion in Two Dimensions Cindy Cao AP Physics 1-212 Changzhou Senior High School of Jiangsu Province Abstract This paper introduces an experiment about launching a water rocket. The projectile motion of this water rocket will be examined.In this experiment‚the water rocket will be launched at 4 different angles 30°，45°60°and 90 °.We will measure the ranges‚maximum altitudes and air time in order to have a better understanding of the projectile motion.As the practical

Pennsylvania State University Lab Report on Experiment 10- The Chemistry of Natural Waters Introduction What is water hardness? Water is extremely important to all living things and even to non-living things‚ indirectly. Therefore‚ the way water travels and gets to a place is also extremely important because its transportation methods determine the chemicals that get involved and added into the water as it travels. This relates to the hardness of water. The hardness of water is basically caused by the

Sacramento tap water reveals ion concentrations of various different dissolved minerals such as calcium (Ca2+) and magnesium (Mg2+). These concentrations are a result of mineral deposits in local lakes and rivers. Perma Pure‚ a gas conditioning products manufacturing company‚ simplifies the mechanism of ion exchange by explaining that water is a solvent that dissolves most ionic bonds when exposed to compounds ("The Mechanism of Ion Exchange"). Therefore‚ as tap water passes through rocks it will

WATER STEWARDSHIP INFORMATION SERIES Hardness in Groundwater February 2007 What is water hardness? Water hardness is primarily the amount of calcium and magnesium‚ and to a lesser extent‚ iron in the water. Water hardness is measured by adding up the concentrations of calcium‚ magnesium and converting this value to an equivalent concentration of calcium carbonate (CaCO 3 ) in milligrams per litre (mg/L) of water. The Guidelines for Canadian Drinking Water Quality Hardness divide hardness

Using a cooling glass of water to determine the area and volume of the curve formed. Research Question: To what extent can a cooling glass of water be modelled accurately and be used to find the area under the curve and volume formed by curve? Data Collection: In order to produce an exponentially decaying graph‚ I had to first heat a glass of water for a certain period of time {150 ml of water}. After the water was heated a temperature probe‚ connected to logger pro and laptop

What organic molecule can be detected with Lugol’s? By using the Lugol’s iodine test‚ we can detect the presence of starches. Why put Lugol’s in the beaker and not the bag? When we put the Lugol’s regent (I2Kl) in the beaker‚ we can observe the effects of osmosis as the Lugol’s regent (I2Kl) solution on the outside of the beaker permeates the intestine (Dialysis tubing) inducing a chemical reaction that will turn the liquid in the intestine (Dialysis tubing) blue-black.
