Informative Speech: Nuclear Energy Purpose: The purpose of this speech is to inform others about the production‚ utilizations and impacts of nuclear energy. I. INTRODUCTION A. Attention Getter: When most people think of nuclear energy‚ the first thing that comes to their minds is a devastating bomb explosion or a nuclear power plant meltdown. But‚ in reality‚ nuclear energy is a sustainable energy source that has an enormous variety of uses. B. Thesis: The uses of nuclear energy range from being a

ENERGY: Energy is the amount of force or power when applied can move one object from one position to another or Energy defines the capacity of a system to do work. Energy exists in everybody whether they are human beings or animals or non-living things for e.g.: Jet‚ Light‚ Machines etc... Energy can have many forms: kinetic‚ potential‚ light‚ sound‚ gravitational‚ elastic‚ electromagnetic or nuclear. The many different natural and renewable energy technologies are by no means breakthrough. Many

Work and Energy Worksheet Section 1 Work: 1. A person pulls a toboggan for a distance of 35.0m along the snow. The force in the rope (tension) is 94.0N. How much work is done on the sled? Solution: W= Fd W= 94.0N x 35.0m W= 3290 Nm or J 2. The cable of a large crane applies a force of 2.2x10^4N to a demolition ball as it lifts it vertically a distance of 7.6m. a) How much work is done on the ball? b) Is the work positive or negative? Why? Solution:

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 Although these units are part of the metric system‚ they have been superseded in the International System of Units by the joule.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:

Discuss the contention that sustainable tourism is‚ perhaps‚ an impossible dream. The definition of sustainable tourism is much debated. However‚ a suitable meaning can be inferred from the broadly used definition of sustainable development‚ an economic process to which sustainable tourism is intrinsically linked. Sustainable tourism would be that which ‘meets our needs today‚ without compromising the ability of people in the future to meet their needs’ (Swarbrooke‚ 1999‚ p. 3). These needs would

disk of radius R = 0.25 m has a string wrapped around it‚ and a m = 3 kg weight is hanging on the string. The system of the weight and disk is released from rest. a) When the 3 kg weight is moving with a speed of 2.2 m/s‚ what is the kinetic energy of the entire system? KETOT = KEwheel+KEweight = (1/2)(I)(w2)+(1/2)(m*v2) =(0.5* v2)(m+1/2M) =0.5*(2.2^2)*(3+(.5*15)) J b) If the system started from rest‚ how far has the weight fallen?

Once installed‚ energy is free Fourteen solar farms have a combined installed capacity of 388.4 megawatts and in 2011 generated 0.1 billion kilowatt-hours. (Source: Canadian Centre for Energy Information compilation‚ 2013) There are now 3‚133 megawatts of solar power installed in the U.S. That’s enough to power nearly 3 million homes. The average cost
