Stiletto heels undoubtedly concentrate a large amount of force into a small area. The great pressure transmitted through such a heel (allegedly greater than that exerted by an elephant standing on one foot) can cause damage to carpets and floors. The stiletto heel will also sink into soft ground, making it impractical for outdoor wear on grass. Taken from wikipedia.org.

Today we learnt about Energy and its Transformations and stuff during Physics. So basically. The law of conservation of energy states that energy cannot be created or destroyed. *TAKE NOTE! Potential Energy Heat Energy Light energy Kinetic Energy Sound Energy Electrical Energy. When we switch on the torchlight,. Tuesday, May 11, 2010. Summarizing chapter 16 (FIRST PART).

Hello, to view all my previous posts please go to "Archives". Thank you! Wednesday, May 5, 2010. What is a moment. Imagine two people pushing on a door at the doorknob from opposite sides. If both of them are pushing with an equal force then there is a state of equilibrium. If one of them would suddenly jump back from the door, the push of the other person would no longer have any opposition and the door would swing away. The person who was still pushing on the door created a moment. What is a moment.

Or you could say that a sphere is the set of all the points that are at the same distance from the center of the sphere. In nature, centrifugal force and gravity tend to make a lot of things into spheres: soap bubbles, for instance, atoms, and planets.

Hello, to view all my previous posts please go to "Archives". Thank you! Saturday, April 3, 2010. Submarines (Diving and Surfacing). A submarine or a ship can float because the weight of water that it displaces is equal to the weight of the ship. This displacement of water creates an upward force called the buoyant force and acts opposite to gravity, which would pull the ship down. Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will. Saturday, April 3, 2010.

Hello, to view all my previous posts please go to "Archives". Thank you! Monday, April 5, 2010. Measuring the volume of a cork stopper. 1) attach weights to it (so it doesn't float). 2) place it in a volume of water. 3) measure the change in height of the water level. 4) take it all out. 5) put just the weights in. 6) measure the change in height of the water level. 7) subtract 6) from 3). 8) convert height to volume by measuring the cross-sectional area of the container.

You use a suction bulb to gather a specific amount of the liquid when using a pipette, and you can push the bulb down to let the liquid out. So, you can control the amount of liquid in a pipette. But with the burette, you open the tap to let the liquid out and close it if you want to stop. But you cannot control the amount of liquid in it. Monday, March 22, 2010. Well in my opinion.
