Sustainable Energy 1. How can electricity be defined? Electricity can be defined as the flow of electrical power or charge. It is a type of energy fuelled by the flow of electrons from positive and negative points within a conductor. 2. What is an electrical circuit? 3. What components are required to create an electrical circuit? In order to create an electrical circuit‚ you need: a) A source of electric power (battery or generator) b) A load to absorb the power (lamp

Questions: 1. When we say that something gives us “energy‚” what does that mean? What is a biological definition of energy? When we say that something gives us “energy” it means that‚ that drink gave us power to get up and do things. It energizes us so we can accomplish something. The biological definition of energy is the strength and vitality required for sustained physical or mental activity. 2. What is the physiological role of each of the molecules in your table? The role of each of the

At the end of the lab all of the matter (such as the string‚ the ball and the books) stayed in the area. The potential energy‚ that was stored in the ball on the high shelf and suspended weights as well as the stored mechanical energy of the sling shot‚ had left the system in the

In today’s world‚ most of us know that it is important to turn off lights and other electrical appliances to conserve energy‚ but not everyone understands that the reason for the emphasis on cutting back on the use of energy is due to the inevitable depletion of our environment’s nonrenewable resources. Of course‚ electric power is not the only factor that has lead to our supply of nonrenewable resources declining in recent decades. The overdependence on natural gas and oil to fuel our cars and

Maltese Solar Energy: The Power of the Sun Nowadays fossil fuels are becoming more scarce than ever. Therefore to produce energy‚ mankind is investing in new technologies that produce energy from renewable sources. Solar Energy is considered as one of the most frequently used renewable energy source in countries from all over the world‚ including our beloved island. Quite a few of Maltese families have installed solar panels in their homes. One of the main drawbacks in installing a solar

Importance of Electrical Energy Electric Energy We need energy in various forms like heat‚light‚sound etc.The development new technology made it possible to convert electrical energy into any form of energy.This gives electrical energy an important position in the world.The running of the modern industrial structure depends on the low cost and the uninterrupted supply of electricity.In short we can say that a country is developed if the per capita consumption of electrical energy is much higher.

PLAN Introduction: After having built up knowledge about the kinetics of reactions I decided to do an investigation in this area. I was initially introduced to this particular reaction1 in EP6.4 and then in AA2.1. I was interested in using this reaction as a means of potentially supporting and quantifying some of the theories that I have studied along with also perhaps extending on them. Aim: Using a clock reaction I shall: Investigate the effect of concentration for each reactant and

Calories: The name calorie is used for two units of energy. Although these units are part of the metric system‚ they have been superseded in the International System of Units by the joule. One small calorie is approximately 4.2 joules. Calories are also most known to be used in foods and diet‚ which is key to athletes. Joules: A Joule is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre. Kilocalories:
