The other 3 percent is filled with 20 other elements‚ which are needed to live. Some of those elements are calcium‚ phosphorus‚ potassium‚ sulfur‚ sodium‚ magnesium‚ and many more. In the circulatory system‚ two elements that are critical to the circulatory system are iron and oxygen‚ without these two elements it would be impossible for the system to function. The circulatory

member in two scenarios (going up and down the stairs of the second floor and the third floor of the Main Building) wherein weight was also considered and following this‚ the power output of each member was also computed. Using the Logger Pro‚ the kinetic and potential energies of a ball in free fall were graphed and compared. At the end of the experiment‚ it was said that member #2 was the most “powerful” among the group since she had the highest power output both in going up and going down the stairs

clipboard glued to various surfaces with diffirentiating frictional properties. In order for us to test the varying Static friction or Kinetic friction we used a Newton force gauge‚ some wooden blocks‚ and a metal weight. The actual experiment consisted of two parts. The first part measured the net force‚ or more specific the net force required to overcome the kinetic friction coefficient‚ to move the block across the frictional surfaces (the Clipboard itself‚ cork‚ rubber‚ and sandpaper).

one twice the mass of the other‚ experience the same force for the same time. What is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? You have to use the conservation of the

QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)

well since the egg broke the moment it landed. Though we managed to calculate the amount of Potential energy at the start and how much kinetic energy it had when it reached the bottom. Things we learned that was relevant to the lab were what Potential Energy and Kinetic Energy was. Potential Energy is stored energy due to objects relative position‚ while Kinetic energy was energy of motion; amount of energy depends on objects mass and velocity. The lab with the roller coaster showed examples of
