Newtons third law of motion By: Crismaily Valdez Evaluate Newton Third law of motion work ● For every action there is a equal and opposite reaction. The Introduction in every interaction‚ there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal

Reaction: The documentary of Al Gore is very interesting‚ because it does not only give you information about global warming but also it will awaken you to take good care of our mother earth. It clearly showed the environmental conditions our planet is facing. Part of the reason why I like it was that Gore presents a powerful message that combines factual information‚ humor and‚ ultimately‚ hopes. I really like how Al Gore relates his life story with what was happening in the earth‚ especially global

Modern History Modern history‚ or the modern era‚ describes the historical timeline after the Middle Ages. Modern history can be further broken down into the early modern period and the late modern period after the Great Divergence. Contemporary history describes the span of historic events that are immediately relevant to the present time. The beginning of the modern era started approximately in the 16th century. Many major events

Solar Energy Essay Fossil fuel comes from the earth‚ from the decomposition of dead living things underground. Fossil fuel is easy to get and is cheap‚ but fossil fuel takes millions of years to form and is not a renewable energy and it contains a large amount of carbon in it. There are some types of fossil fuel like; coal‚ natural gas and petroleum. Fossil Fuel makes electricity‚ motor oils and other things that are used in our daily lives. When fossil fuels are burnt‚ they produce heat‚ which

Effects of Water Pollutions Water is important for the existence of life on earth. All organisms require it and aquatic plants and animals live their life in water. Water pollution occurs when you have toxins and pathogens present in water in dangerous amounts than permissible. One of the worst forms of pollution in the ecosystem is water pollution. When you hold a glass of water it may appear to be clean and clear. But the fact is there are millions of microscopic pollutants suspended

Combustion of Alcohols Purpose: The purpose of this investigation is to use calorimetry to determine the molar enthalpy change in the combustion of each of a series of alcohols. Question: How do the enthalpies of combustion change as the alcohol molecules become larger? Prediction: I predict the bigger the molecule the more the energy will be released. Materials: On lab sheet Procedure: On lab sheet Observation: On other page Analysis: b) i) Ethanol – q=(100g)(4.18J/g/C)(25.5C) q=10659J

WATER QUALITY AND CONTINMINANTION Introduction I. Body Paragraph #1 – Background~ Water quality is decided by assessing three classes of attributes: biological‚ chemical‚ and physical. There are criteria of water quality set for each of these three categories of properties. The standards for drinking water are developed by the Environmental Protection Agency (EPA)‚ World Health Organization (WHO) etc. All municipal (public) water supplies must be measured against these standards. Testing how
