is a tractor beam. Tractor beams are possible, but they are not yet advanced to the extent of Star Wars or alien abductions. The theory is that beam can reel a particle in towards the source. Currently, there are three types of tractor beams, sonic, light, and laser beams. So far, each kind of beam has only been created to move particles or teeny tiny beads. There has been a lot of work towards tractor beam technology. There have been many advances in tractor beam technology such as sonic,…

Principle of centrifugation: Particles suspended in a solution are pulled downwards by Earth’s gravitational force. In a solution, particles with higher mass…

including the transformation of radiation into matter which follow the Big Bang The Universe started with a Big Bang. At the beginning of the Big bang, there was only radiation. However over time ranging from 300 seconds to 1 million years, the particles combined to form atoms…

1. There is not much known about phage influence on microbial communities in extreme thermal environments. What may be one of the roles these phages have in this environment? - Phages are an important components of surface hot springs, they are abundant and active components of hot springs capable of killing a significant proportion of the resident microbial populations. They play an important role as predators of hot spring microbial communities and influence carbon and nutrient cycling in…

represents the energy loss at the particle surface due to the collisions with the surrounding gas molecules. There is no simple theory to explain the cooling mechanism of the particles. During the laser pulse, the particle achieves the peak temperature and emit thermal signal. After the laser pulse duration, the particle starts to cool down. The cooling of the particles is characterized by a decay function. The decay of LII signal provides information about the primary particle size and size…

Alpha (α) Radiation The alpha radiations particles have 2 protons and 2 neutrons which are in a helium nucleus. As the alpha particles emit the helium nucleus the nucleus gives away the two protons and two neutrons. As a result of this the mass number will reduce by 4 and the atomic number will result in reducing by 2. This is known as alpha decay. One source of alpha radiation could be plutonium 239. The alpha particles have many characteristics. First of all the alpha radiation has a helium…

the substance as well. If there is more internal resistance or friction, then the particles of the substance won’t slid past each other as easily and therefore make the substance more viscous. On the other ha2145nd, if there is less internal resistance or friction, then the particles of the substance will slide past each other more easily and therefore make the substance less viscous. This has to do with the particle model of…

container, and shot a stream of electrons across the glass tube. When the particles stuck to the other end of the tube, it created a patch of light that indicated where the particles landed. Thompson discovered that by using a magnetic field, he could move and deflect particles. He found that particles would always move towards the positively charged side. By using a Cathode Ray Tube, Thompson was able to conclude that some particles are negatively charged; therefore, discovering electrons.…

how gas particles are in constant motion and create collisions that results in pressure. The theory is split up into four different postulates. Number one explains how gases are made up of tiny particles. To prove that those particles take up space, postulate #2 tells us that the particles collide with each other and those collisions make pressure. Pressure can either expand or shrink a flexible container, depending on how many particles are in that container. If there are more particles then…

Beta particles are caused when a neutron in an unstable atom splits apart to form a proton/positron and an electron, the electron is referred to as a beta negative particle and the positron is refered to as a beta positive particle. The electron is shot from the nucleus and out of the atom. Beta particles have high penetration ability and low ionisation ability, beta particles can travel over one centimetre into a human body, they can travel…
