Beta decay occurs when the neutron to proton ratio is too great in the nucleus and causes instability. And gamma decay occurs when the nucleus has too much energy. 3. What is meant by nuclear fission? Nuclear fission is a nuclear reaction that produces a lot of energy, and occurs when the nucleus of an atom splits into two parts spontaneously or with the impact of another particle.
How Do Photocopiers, Powder Paint and Precipitators Work? Photocopiers, powder paint and precipitators are all very useful, and work in a very specific way, static electricity is the base of this. Static electricity is a collection of immovable charges on an object or molecule. Static build up is caused by friction, when two insulating materials are rubbed together electrons are taken from one and moved onto the other. This leaves a positive charge on one material and a negative one on the other, the charge depends on the material.
On top of this, the helium nucleus is clearly labeled and is shown containing two neutrons and two protons (which are also labeled using an “N” and a “+”). Similarly, my model of beta decay is labeled in the same manner as that of the alpha decay model. In beta decay, an unstable atom uses its natural tendency to become stable to “transform” one neutron into a proton. Subsequently, the new positive charge requires an electron to be released from the atom’s orbit. This process is shown clearly in my model due to the fact that it states that the atom gets the energy to carry out this process from the instability of itself.
The magnetic field permeates the tissue and causes the nucleus scale magnets in the tissues to rotate. By observing what frequencies are absorbed by the atoms the doctors can determine what sorts of atoms are present at a particular place in the body. 2. Explain how a sound is actually a form of energy? In what medium do sound waves travel?
With Magnetic force no movement is necessary in contrast to electric force. C. The last part requires you to compare and contrast motors and Generators, C) In a generator the interaction of moving objects creates a magnetic field and that field generates the electric power. An electric motor uses energy created by a magnetic field. FRI. POST Thread
The particles of a substance that is "cold" are moving slowly, and the particles of a substance that are "hot" are moving quickly. The second one is Electric energy; it consists of moving charged particles (usually electrons). The moving electrons can induce heat, light, or magnetic fields to turn motors. Electricity is a type of kinetic energy. 5.
Nuclear fusion and nuclear fission are two different types of energy-releasing reactions in which energy is released from high-powered atomic bonds between the particles within the nucleus. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one. Nuclear fission is a class of nuclear change. Nuclear fission occurs when a very heavy nucleus splits into two smaller nuclei, each more stable than the original nucleus. Most fission reactions happen artificially by bombarding nuclei with neutrons.
Respiration can occur at all times in a cell because no stages in the process require sunlight. Whereas photosystem II requires sunlight for the photolysis of water and to excite electrons, so photosynthesis can only happen in a cell when sunlight is present. For example, photosynthesis cannot take place during the night but respiration can. Both processes take place inside the cells. The site of photosynthesis is
Lactic Acid Fermentation can only produce 2 ATP (as in alcoholic fermentation) but ethanol is not produced. Lactic acid is toxic to cells, which means anaerobic respiration can only occur for short
BETA PARTICLES Beta rays are much lighter energy particles. The beta particle is an energetic electron given off by the nucleus of unstable isotopes to restore an energy balance. They leave the nucleus at a speed of 270,000 kilometers per second. They can be stopped, for instance, by an aluminum sheet a few millimeters thick or by 3 meters of air. The RS-500 can detect most energetic beta particles through the case.
