Surface energy

Inelastic collisions occur when the kinetic energy of an object is not conserved, but converted into other forms of energy, such as heat or potential energy. As such, they still obey the conservation of energy principle that energy cannot be created or destroyed. When two bodies undergo an inelastic collision, their combined initial kinetic energy is not equal to the final kinetic energy of the system. When a tennis ball bounces on the ground, the kinetic energy that the ball possesses just…

Power Plant. His job place always dealing with radiation around him and his co-workers. But we don’t know deep details about radiation. Let’s start by talking about the thermal radiation. Thermal radiation is energy where it transfers by the emission of electromagnetic waves. The waves hold energy away from releasing object. For a normal temperature, the radiation is in the infrared region of the electromagnetic spectrum. The relationship ,conducting the net radiation from a hot object is…

produce high energy electron beam. A magnetic condensing lens is used to condense the electron beam and a scanning coil is arranged in-between magnetic condensing lens and the sample. The electron detector (Scintillator) is used to collect the secondary electrons and can be converted into electrical signal. These signals can be fed into CRO through video amplifier as shown. In order to produce images the electron beam is focused into a fine probe, which is scanned across the surface of the…

increase in kinetic energy, the molecules vibrate and this vibration passes the heat to the surrounding molecules. Conduction only occur in solids. Convection is a type of heat transfer that only occurs with liquids and gases because it involves the liquids and gases physically moving, which a solid is unable to do. Convection happens when there is a difference in temperature between the two parts of a liquid or a gas. The warmer part rises because it expands and gains more energy and the cooler…

How much energy does dribbling take? We understand that dribbling in various places requires a lot of energy. Basketball players know that certain playing areas such as asphalt, hardwood, and cement requires different types of dribbling. In order to dribble the ball players have to keep putting energy into the ball. Energy is required to dribble a ball as well as more energy may be required to dribble in different places. You would soon find out why energy is required to dribble the ball and how…

GEOTHERMAL ENERGY 1.1 INTRODUCTION AND DEFINITION Geothermal energy is the utilization of heat present in the deep earth for the purpose of power generation or other direct use application. In general terms, geothermal energy consists of the thermal energy present in the Earth’s crust. Thermal energy in the earth is distributed between the constituent host rock and the natural fluid that is contained in its fractures and pores at temperatures above ambient levels. Globally, the most commonly…

What the stream team will be doing is going to the stream and seeing how much nitrate, phosphates, dissolved oxygen, turbidity, temperature, and pH is in the water. The stream team will look at the effect on water quality, the effect on plants and animals, the acceptable levels for swimming, sources and sources categorized, the best management practices, whether the sources are point source, or nonpoint source pollutants, and the test results. The stream team will be doing all of those topics…

Communal Areas Cleaning London Do you own a large commercial property, student property, flat share or office block? If you do, then you will have to address cleaning communal areas. The reason is because you must provide residents or visitors to such property with healthy living conditions that stand up to certain standards. You could try and take on such task on your own, but odds are it will be too large a job. By outsourcing the job to a communal areas cleaning company, you can take the…

Controversy exists over whether biodiversity issues have negative impacts on the ecosystem and environment. While some well-intentioned people believe that the environment would not be affected by biodiversity (biological diversity) problems, I hold onto the view that biodiversity issues strongly influence ecosystems in that they not only effect on the land, but also will create significant challenges for the air and the water resources. Biodiversity is commonly defined as the variety of all…

Dark Web entails, there are also some fascinating facts about it. For example, did you know that it has been reported that the Deep Web itself “is approximately 400 to 550 times larger than the surface web, and also contains 7,500 terabytes of information compared to the 19 terabytes of info in the surface web? Also, the…
