of water and paper towels (1). Description of the apparatus: The apparatus consists of a 110 cm long uniform graduated glass tube of 1(1/2) diameter connected to a rubber tubing and a water reservoir supported by a stand. The level of water in the glass tube is changed by moving the attachment to the reservoir (2). Diagram of Apparatus: Theory: Transverse wave- if the particle in a medium vibrates at right angles to the direction of propagation of a wave. It is said to be transverse wave

While the 117 year old Mullaperiyar Dam is technically very dangerous calling for de commissioning‚ it is illogical for the people of the area to panic of any imminent danger‚ says the Forum of the Civil Engineering Post Graduate Scholars. A discussion organized by the forum observed that relevant technical parameters are overlooked by even the so called experts. Erroneous factors The Probable Maximum Flood (PMF)‚ an important parameter to evaluate the danger posed by dams arrived for the area

Global warming is the gradual heating of the earth by the trapped infrared rays by the thickening ozone layer caused by carbon dioxide emissions. Fresh water stored in lakes‚ rivers and reservoirs is evaporating due to the rising temperature. This has been a major issue in places such as Las Vegas‚ a city in a MEDC with high population demand of water where 90% of water it gets is from the Colorado River basin which has dried up more than

Running Head: Energy Conversion Energy Conversion Marlon Walker Professor Abdul Kahn SCI 110: Integrated Science October 21‚ 2011 Abstract Energy conversion has been a topic of debate and research for many years. Scientists conduct experiments in hopes of finding an alternative to relying on burning fossil fuels for electricity. While companies who believe their alternative is the best choice‚ debate over whose source is the “greenest”. Whether it be biomass‚ hydroelectricity‚ solar

Water was an essential resource for the Romans. There was water to be found easily‚ but how would they move it to their cities in a cleaner way? Luckily‚ the Romans thought of this idea and began working. This water collecting pipe‚ was famously known as the first aqueduct. The Romans were the first to build the aqueducts‚ so they could bring constant flowing water to the city. The water could be used for baths‚ latrines‚ fountains‚ and private households. The aqueducts improved the water

More recently‚ reforestation and changed agricultural practices have improved this somewhat. (Pearson Education‚ 2011) Nitrogen is needed by all organisms to make proteins. Almost 78% of the atmosphere is nitrogen thus meaning that the main reservoir for the nitrogen cycle is the air. This atmospheric nitrogen is called non-reactive nitrogen. This form of nitrogen cannot be used directly by plants or

such as perlite‚ gravel‚ mineral wool‚ expanded clay or coconut husk. Researchers discovered in the 18th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions‚ soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water‚ plant roots are able to absorb them. When the required mineral nutrients are introduced into a plant’s water supply artificially‚ soil
