Sir Isaac Newton was a famous scientist who invented the Universal Law of Gravitation in 1687. His law of gravity describes the force amongst every object that contains mass. Newton devised his idea of the law of gravity when he observed an apple fall from a tree. This then lead him speculating about whether the same force that was upheld by the apple was also maintained by the moon. Sir Isaac Newton then reached to the discovery that both the apple and the moon were motivated by the force of gravity

Food has become easier to prepare. Has this change improved the way people live? Use specific reasons and examples to support your answer. Of course‚ nowadays food has become more easier to prepare. Think about microwave-ovens‚ mixture‚ grinding machine‚ rice-cooker‚pressure cooker‚I think you already got the answer‚ right? In my point of view‚ the improvement of food preparing has obviously changed our lifestyle in a better way. These days‚ people need not use effort‚ every things are kept in

The electromagnetic spectrum is made up of six different types of waves. Radio waves‚ Microwaves‚ Infrared waves‚ Visible light‚ Ultraviolet light‚ X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultraviolet light can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers

facility that gathers sunlight‚ converts it into microwaves or laser beams‚ and transmits those to the ground; and a power receiving facility on the ground. Space-based solar power essentially consists of three elements: • a means of collecting solar power in space‚ for example via solar cells or a heat engine • a means of transmitting power to earth‚ for example via microwave or laser • a means of receiving power on earth‚ for example via a microwave antenna SBSP uses photovoltaic conversion

Ionisation Uses of ionising radion Danger of ionising radiation Non ionizing radiation refers to any type of electromagnetic radiation that does not carry enough energy per quantum to ionize atoms or molecules—that is‚ to completely remove an electron from an atom or molecule. Instead of producing charged ions when passing through matter‚ the electromagnetic radiation has sufficient energy only for excitation

the environment. This includes concepts such as atom economy‚ less toxic reagents‚ catalysis‚ and alternative energy sources. You will notice‚ for instance‚ that this reaction does not use a solvent. Consider also the amount of energy needed to microwave the reaction for 10 minutes vs. the traditional reaction conditions of heating to 250 °C for 20-30 minutes. The principle of atom economy attempts to avoid "wasting" reactant atoms. A calculation of atom economy will show the efficiency of the
