radiating electric field (or electromagnetic signal) produced when radio stations broadcast? Include a description of what is producing the signal as well as the reasoning behind how this could produce a signal. We know that electromagnetic radiation is produced by accelerating charges. In the radio transmitter‚ electrons oscillate up and down and are thus accelerating. An electron will exert a force on another electron when they are some distance away‚ like charges repel. When the electron in

GENETICALLY ALTERED CORN Corn or maize only exists in its modern form because of humans. Evidence from archaeological And genetic studies suggests that corn was bred and cultivated by early Mexican inhibiters as Early as 10‚000 years ago. The early Mesoamericans managed to develop corn from its grassy Ancestor by selective breeding. Corn was bred from a wild grain called teosinte. Teosinte is so unlike modern corn that originally botanists didn’t think the two were even related. An ear

Identification: Corn snakes are a relatively small and slender species. Corn snakes have a very vibrant colouration consisting of bright oranges‚ orangey-reds and reddish-browns. Their base colour is usually an orange to reddish-brown colour with a variety of different patters across the entirety of its body. Herpetologists at the North Carolina Museum of Natural Sciences‚ described corn snakes scale and colour patterns as "dark-margined red or brown mid-dorsal blotches and smaller lateral blotches

Bubble-Ology Glycerin Sugar Corn Syrup Introduction The secret to a good bubble is something called surface tension‚ an invisible bond that holds water molecules together. Water is a polar molecule‚ so it has plus and minus ends just like magnets that attract each other. When the water molecules align with each other they stick together‚ creating surface tension. You might think that it is the surface tension of the water that holds the skin of a bubble together. Actually‚ the surface tension

heat in white‚ black and silver will be explored. Infrared radiation is invisible radiant energy‚ it lies between the visible light and the microwave portion of the electromagnetic spectrum. Heat is the main source of infrared energy‚ heat is produced by the movement of atoms and molecules. This experiment was conducted to investigate how black‚ white‚ and silver cans would absorb heat. The electromagnetic spectrum is made up of gamma rays‚ X-rays‚ ultraviolet‚ visible‚ infrared‚ microwaves and

About Radiation: Radiation is an energy that is transmitted in the form of waves or tiny particles. These are electromagnetic waves‚ which are classified as ’ionizing radiation’ and ’non ionizing radiation’. Electromagnetic radiation is when an object gives out electromagnetic radiation. For example when you on a torch light‚ the light is an example of radiation. Ionising radiation has more energy than non ionising radiation. Therefore it is enough to cause chemical changes by breaking chemical
