heavier‚ it will sink. The force of buoyancy is important in many different areas‚ and especially in the making of ships. The surface area that is touching the water of the ship is very large‚ due to the shape of the hull‚ and that‚ beside the density of the ship‚ is what keeps the ship floating. An important example of how surface area affects buoyancy is when people float in the water. Everyone knows that it is much easier to stay afloat when we are lying on our backs than when we are in a standing

For example‚ Business Week has recently run two cover stories‚ one titled “Who Can You Trust?” (October 5‚ 1998) and the other titled “The Numbers Game” (May 14‚ 2001)‚ that suggest that the credibility of earnings reports is being eroded by earnings management.

(v1). Using the density of water (1.0g/mL)‚ this volume can be converted into mass. This concept is shown by the equation [M= (v2-v1) x (1.0g/ml)]. To determine the energy consumed by the melting ice (E)‚ we must determine the energy released by the water to make the ice to melt. This energy can be determined by using the equation to calculate the energy of the temperature changes. The mass of the water releasing heat is determined by multiplying the initial volume (v1) by the density of water (1.0g/mL)
