Coaches are responsible for training athletes, scheduling practices and managing equipment. Most coaches work non-traditional hours, including evenings and weekends. Physical education teachers and coaches can combine their interest in being active in their daily lives with a career helping others to do the same. Teaching is focused on imparting knowledge and learning, where the teacher is in charge of the interaction. It has little to do with the student as an individual. Coaching is centred around the student. Coaches focus on the development and guidance of students.

A Constitution refers to a system of laws and principles that act as a basis for governance in a country. There are two types of constitutions.

A Constitution that has been systematically and meticulously written down and embodied in a single document is known as a Written Constitution.

An Unwritten Constitution is the one in which no provisions or laws of the constitution are set in writing but they are documented despite not being incorporated in a single book.

When hydrogen gas present on discharge tube passed through high voltage & low pressure, the radiations emitted passed through spectroscope and spectrum is obtained on photographic plate. Hydrogen spectrum contains several lines known as series. The series present in hydrogen spectrum are:-

Created in China, the printing press revolutionized society there before being further developed in Europe in the 15th Century by Johannes Gutenberg and his invention of the Gutenberg press. German goldsmith Johannes Gutenberg is credited with inventing the printing press around 1436, although he was far from the first to automate the book-printing process. Woodblock printing in China dates back to the 9th century and Korean bookmakers were printing with moveable metal type a century before Gutenberg.

Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. ... For example, when a pendulum swings upward, kinetic energy is converted to potential energy. Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.

Temperature , climate, area, rainfall, etc are the two factors that determine the growth of natural vegetation. Temperature and humidity are the main factors which determine the character and extent of vegetation. E.g. an area with high temperature and high humidity supports evergreen forest, while an area with high temperature and low humidity supports thorny bushes (desert).

Physical and Human Geography is the principal branches of Geographical sciences. Physical geography is what we are more familiar with as it involves earth's land areas, bodies of water, plant life etc. ... Human geography is more about people's religion, culture and way of life. Under physical geography we study the things like mountains, rivers, natural vegetations and animal life, etc. The sub-fields of physical geography are landforms, climate, water, soil, etc. Bio-geography is the study about plants and animals found on the earth's surface and in hydrosphere.

A process used to determine the viability of a project or procedure based on the experiential application of clearly defined and repeatable steps and an evaluation of the outcomes. The goal of a systematic approach is to identify the most efficient means to generate consistent, optimum results. The systematic approach studies only one issue and continues to examine its spatial variations. That means related to different spaces, you study your location. On the other hand, the regional approach studies the multiple characteristics after dividing or segmenting the location at hand, on the basis of region.

Physical geographers study Earth's seasons, climate, atmosphere, soil, streams, landforms, and oceans. Some disciplines within physical geography include geomorphology, glaciology, pedology, hydrology, climatology, biogeography, and oceanography. Its subject matter is the physical and human phenomena that make up the world's environments and places. Geographers describe the changing patterns of places in words, maps, and geo-graphics, explain how these patterns come to be, and unravel their meaning.

The basic role of accounting is to provide relevant financial information to the businessmen and the stakeholders. Furthermore, facilitating the decision making processes and keeping them updated. There are two types of functions of accounting, first, historical functioning and second, managerial functionals. 

There are five basic roles or functions within the department:

• Accounts receivable.
• Accounts payable.
• Payroll.
• Financial controls.
• Financial reporting.

Geography has been branded a unique science of bridging the gap between social sciences and natural sciences. Hence we have two main sub-disciplines in geography. These sub-disciplines are Physical Geography (natural sciences) and Human Geography (social sciences). Geography's two main branches are physical geography and human geography. Geographers identify and locate major physical and human geographic features of various places and regions in the world.  Geography is the study of places and the relationships between people and their environments. 7 - 12+ Earth Science, Geography, Human Geography, Physical Geography.

Solutrean paintings include images of horses and goats, as well as handprints that were created when artists placed their hands on the cave wall and blew pigment over them to leave a negative image. Numerous other caves in northern Spain contain Paleolithic art, but none is as complex or well-populated as Altamira. The paintings may have been used in religious rituals.
In terms of a specific purpose, some experts believe that the paintings may have been used during a ritual where a shaman would enter the cave and go into a trance in order to make contact with spirits.
