Introduction What is electrical resistance? Electrical resistance is what limits the current inside a circuit. What effects resistance? ?óÔé¼?ó Length: The longer the length of a wire the higher the resistance level will be. ?óÔé¼?ó Diameter: The thicker the diameter of a wire the lower the resistance level will be. ?óÔé¼?ó Material: Insulators have a very high resistance level and conductors have a very low resistance level. Metals are normally good conductors and plastics are very good insulators. In this assignment I am going to investigate how the length of a wire affects...

My investigation showed that up to 70cm my graph agreed with my prediction but after 70cm I'm not sure if the resistance is proportional to the length. I could have taken more readings on my graph after 70 cm and I could have taken measurements for every 2 cm after the 70cm point. I could also take my measurements up to 10 m to see if the resistance was proportional to the length for a longer length.

We are trying to find out what factors affect frictions. Friction is the force that opposes motion, or makes it difficult an object to move across a surface. The amount of friction depends on the surface type and the force pressing two objects together. I am going to...

Life is sustained by the energy from the sun. Without the sun all plants and animals would die. The sun provides 99.98% of the energy, which naturally flows through the surface environment of the earth. Put another way, the sun supplies 5000 times more energy than all other sources combined....

For many centuries, scientists have been puzzling over the question "What is everything made of?". There have been numerous theories and hypotheses drawn up over the millennia, but only one can be correct. This is atomic theory ?óÔé¼ÔÇ£ that everything is composed of atoms, which is the smallest any one...
