Because the work is directly proportional to the displacement given a constant force while power is indirectly proportional to work. Therefore we can conclude that power is also directly proportional

Osmosis on Egg Introduction: The purpose of this lab was to test the effects of hypertonic‚ isotonic‚ and hypotonic environments on the weight of a shell-less egg. We tested the weight of the egg after thirty minutes in water as well as corn syrup. I hypothesized that when the egg was placed in water‚ it would swell and gain weight because it was in a hypotonic environment. That hypothesis was correct as the egg grew slightly and the weight when up. I also hypothesised that when the egg was placed

to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears. The reason for this is because vinegar has acetic acid and the shell has calcium carbonate‚ when these come into contact it produces carbon dioxide. This is the reasoning for the little bubbles when the egg is first put into the vinegar. After the shell discinigrates it will become rubbery from the acetic acid‚ at this point the egg could very well bounce. | |

make more researches about it. In this case‚ the one I am interested is egg in a bottle. Secondly‚ we have to make a question or problem which we will try to answer at the end of the experiment. For this experiment‚ my question is what (will) happen when air molecules expand. Thirdly‚ created the hypothesis to predict or guess what will happen in this experiment. Here‚ I think that air pressure will make the egg fit through the mouth of a bottle. After we have a topic‚ question and hypothesis

Cody Morton 10 October 2011 Drop in the Bucket Imagine a family that is struggling to get by and are suddenly stripped from their suburban home because of a natural disaster‚ such as a flood‚ that tore through the house like it was butter‚ and flooded their basement to halfway up their stair case to the second level. Everything they had worked for‚ all the memories made and all of their most prized possessions were lost. But the insurance denied the claim and did not give you any money to rebuild

these patients is known as “foot-drop.” Foot-drop is the result of weakness or damage to the common peroneal nerve or a paralysis of the tibialis anterior muscle causing an inability to dorsiflex the foot during the swing phase of gait. This results in the patient having to clear the toes of the effected foot by using some type of compensatory motion of the legs or hips. There are a number of techniques that can be used to help to reduce the effects of foot-drop‚ one of the oldest and most common

Physics (from Ancient Greek: φυσική (ἐπιστήμη) phusikḗ (epistḗmē) “knowledge of nature”‚ from φύσις phúsis "nature"[1][2][3]) is the natural science that involves the study of matter[4] and its motion through space and time‚ along with related concepts such as energy and force.[5] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[a][6][7] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy
