Transformer

A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding (Stairway,Walking) creates a varying magnetic flux in the transformer's core, and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF) or "voltage" in the secondary winding. This effect is called mutual induction. If a load is connected to the secondary, an electric current will flow in the secondary winding and electrical energy will be transferred from the primary circuit through the transformer to the load. In an ideal transformer, the induced voltage in the secondary winding (VS) is in proportion to the primary voltage (VP), and is given by the ratio of the number of turns in the secondary (NS) to the number of turns in the primary (NP) as follows:

Stairway

Stairway, staircase, stairwell, flight of stairs or simply stairs are names for a construction designed to bridge a large vertical distance by dividing it into smaller vertical distances, called steps. Stairways may be straight, round, or may consist of two or more straight pieces connected at angles. Special stairways include escalators and ladders. Alternatives to stairways are elevators, stairlifts and inclined moving sidewalks as well as stationary inclined sidewalks. The step is composed of the tread and riser. Tread - the part of the stairway that is stepped on. It is constructed to the same specifications (thickness) as any other flooring. The tread "depth" is measured from the outer edge of the step to the vertical "riser" between steps. The "width"

Walking

Walking (also called ambulation) is the main form of animal locomotion on land, distinguished from running and crawling.[1][2] When carried out in shallow waters, it is usually described as wading and when performed over a steeply rising object or an obstacle it becomes scrambling or climbing. The word walk is descended from the Old English wealcan "to roll". Walking is generally distinguished from running in that only one foot at a time leaves contact with the ground; for humans and other bipeds, running begins when both feet are off the ground with each step. (This distinction has the status of a formal requirement in competitive walking events, resulting in disqualification at the Olympic level.) For horses and other (Rain) quadrupedal species, the running gaits may be numerous, and while walking keep three feet at a time on the ground. The average human child achieves independent walking ability around 11 months old.[3] For humans, walking is the main form of transportation without a vehicle or riding animal. Although walking speeds can vary greatly depending on factors such as height,

Rain

Rain is liquid precipitation, as opposed to other kinds of precipitation such as snow, hail and sleet. On Earth, it is the condensation of atmospheric water vapor into drops heavy enough to fall, often making it to the surface. Rain is the primary source of fresh water for most areas of the world, providing suitable conditions for diverse ecosystems, as well as water for hydroelectric power plants and crop irrigation. However, not all rain reaches (Door) the surface; some evaporates while falling through dry air. This is called virga, a phenomenon

Shower

A shower is a device for washing, typically consisting of an enclosed area and an overhead nozzle. To use a shower, a person stands in the enclosed area while the nozzle sprays water down on the body. Showers are primarily used for hygiene and washing purposes and are (Jet Airliner) often installed in bathrooms. The practice of using a shower to promote

Jet Airliner

A jet airliner is an airliner that is powered by jet engines. This term is sometimes contracted to jetliner. In contrast to today's relatively fuel-efficient, turbofan-powered air travel, first generation jet airliner travel was noisy and fuel inefficient. These inefficiencies were addressed by the invention of turboprop and turbofan engines.

Forest

A forest is an area with a high density of trees. There are many definitions of a forest, based on the various criteria.[1] These plant communities presently cover approximately 9.4% of the Earth's surface (or 30% of total land area) in many different regions and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. Although a forest is classified primarily by trees a forest ecosystem is defined intrinsically with additional species (Semi-trailer truck) such as fungi.[2] A woodland
