To identify characteristics of a sample in your survey, there are many factors to consider of your samples. The first four characteristics you need to focus on are gender, age, income level, and education level. All four of these characteristics must be proportional to that of the population. You also need to consider the geographic location. Only take samples from the immediate geographical area. Finally, an important characteristic of the survey is the sample size. You do not want to ask to...

This demonstrates the difference between hard polymers and soft polymers. The bag does not leak water as it molds to the softer polymer of the bag. If the pen had poked a harder polymer, most likely, there would have been leaking from the holes. This demonstrates characteristics of water, and how polymers can work. This also shows how certain leaks can be stopped.

Newtons proposed the concept of inertia. According to him an object at rest tends to stay at test and an object in motion tends to continue in motions unless acted up on by an external force. This is the principle of inertia. The tendency of the body to continue to stay as it was is called its inertia. You can demonstrate this principle with a simple experiment. As shown in the video when the hoop is pulled out the pen cap falls in to the bottle. Here the hoop is acted upon but the cap is not...
