Nuclear weapons cause unimaginable death and destruction. Without a doubt‚ these are the most powerful weapons mankind has ever built. However‚ there is also a scientific side to this weaponry which Teddy Roosevelt may have indeed called very big sticks. Nuclear weapons work by releasing the enormous amounts of energy that are contained in the bonds of atoms. The bonds of atoms can be broken in two ways. The first way is by fission‚ and the second way is by fusion. Fission works by the splitting

LDR Circuit Diagram: Here is the schematic for the circuit: Light Dependent Resistors Light Dependent Resistors (LDR) are also called photoresistors. They are made of high resistance semiconductor material. When light hits the device‚ the photons give electrons energy. This makes them jump into the conductive band and thereby conduct electricity. A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases

Negative Effects Of Ionising Non ionising: There are negative effects on ionising and non ionising radiation that we are exposed to everyday. For example‚ microwave use microwaves‚ toasters use infrared red‚ TV use gamma rays and we use mobile phones that also use microwaves. These are all types of radiation which can effect

group. Radiation is energy that travels and spreads out as it goes‚ visible that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves‚ infrared and ultraviolet light‚ X-rays and gamma-rays. Hotter‚ more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like

weather forecasting I can only come to one conclusion that when all is considered the best forecasters can only give an educated guess of what is in store for weather. Through the many means at their disposal‚ such as satellites‚ ships at the ocean‚ infrared‚ radio‚ and radar transmissions even with all of these techniques no prediction is 100% accurate. One question that I asked myself was "when was the first weather forecasting ever done?"‚ I found out that in 1863 in Britain there was a united forecasting

Florida Institute of technology | FSO Report | | | Rami nahas | 4/29/2011 | | Free space optical communication is the most growing communication because it is easy to install and has a high speed because the signal is transmitted in the air. So that will introduce the atmospheric affect in the optical wave propagation. Atmospheric turbulence causes fluctuations in both the intensity and the phase of the received signal. So we need to study the effect and the limitation if we

Auto smart – A new point of view: Module 1 – What is fuel efficiency and why is it important 1) Carbon Dioxide is a green house gas because it transmits visible light but absorbs strongly in the infrared and nearly-infrared. 2) The climate change is creating congestion and increasing urbanisation. Module 2 – Fuel efficient driving 1) In order to be more fuel efficient you may buy a car that is easy on gas and not a gas guzzler‚ you can carpool with someone so they aren’t using their gas and
