Energy Systems Assignment By Thysje Fartlek Training Before we started the fartlek training‚ our bodies were using the aerobic system and bi-products of this system are carbon dioxide (CO2) and water (H2O). Our heart rate (HR) was low‚ 60-70 beats a minute‚ and our breathing rate (BR) was slow and deep‚ 1 breathe about every 6 seconds. The demand for fuel was low because we didn’t need to supply the muscles in our body quickly. Once we started walking‚ the demand for fuel increased but only

are two primary methods for generating electricity from water. One method uses the energy potential of trapped water in dams in a more sophisticated version of the water wheel‚ and the other method of generating electricity is to capture energy from ocean waves. Electricity generated from water is entirely renewable‚ sinccete water is an abundant natural resource First method:When a dam is used to generate energy‚ tunnels are installed in the dam when it is built. These tunnels are lined with turbines

Examples of Radiant Energy The term radiant energy refers to energy that travels by waves or particles‚ particularly electromagnetic radiation such as heat or x-rays. Radiant energy is created through electromagnetic waves and was discovered in 1885 by Sir William Crookes. Fields in which this terminology is most often used are telecommunications‚ heating‚ radiometry‚ lighting‚ and in terms of energy created from the sun. Radiant energy is measured in joules.
