Osmosis and the Egg Lab Report By: N. Mullins Date: January 20‚ 2011 Introduction This lab was designed to explain the different things osmosis does. Osmosis is the diffusion of water across a semi permeable membrane. Over three days we tested the egg in three different solutions to observe the changes. On Day 1‚ the main question we answered was what happened to the egg when it was placed in vinegar? Before doing this I came to my hypothesis was that the vinegar would eat away at the shell and eventually

Price discrimination in practice First and third degree discrimination in the train tariffs‚ etc. Price discrimination basically involves charging a different price to different groups of people for the same good.

Second‚ the firm must be able to separate markets and prevent black market. Third‚ there would exist different consumer groups who

The purpose of the egg crash is to design‚ build‚ test‚ and evaluate a landing pad to protect an egg from the collision of a hard surface falling from various heights. An individual should be able to describe the collision in terms of changing momentum‚ impulse‚ impact force‚ and impact time. All moving objects have a quantity of motion‚ otherwise known as momentum. Momentum of a moving object can be found by multiplying the mass of the object by the velocity. Because mass is measured in kilograms

In the actual productivity is affecting more the productivity in service than manufacturing companies. But still bad behaviors poison

our egg drop project were momentum and energy. In the project‚ we saw how momentum increases as a normal egg without anything to slow it down would crack. That was because the longer that the egg fell‚ the more momentum the egg gains. We also saw that by adding resistance during the fall‚ such as a plastic bag “parachute”‚ would slow down the egg enough so that it would not crack when it reached impact with the ground. The other concept that was discussed was energy. We saw that before the egg is

Elasticity is a measure of responsiveness. It shows us how much something changes when there is another change in one of the other variables that determines it. There are three elasticities of demand that we consider‚ price elasticity of demand (PED)‚ income elasticity of demand (YED) and cross elasticity of demand (XED). An important aspect of a product’s demand curve is how much the quantity demanded changes when price is changed. The economic measure of this response in the price elasticity
