The Pyramids of Giza and the Great Sphinx | The Relevance to Mathematics | The Pyramids of Giza and the Great Sphinx are modern wonders that were made in ancient times. The Sphinx and the Pyramids of Giza were made in the time of ancient Egypt. The Sphinx was built by ordinary Egyptians‚ under the command of a Pharaoh. The sphinx is a creature that appears in Egyptian mythology as a monsters used by the magicians of the house of life. The house of life was a set of magicians that fought to

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

Direct energy conversion system Direct energy conversion systems that could operate in the 100-700°C temperature range with high efficiencies (>30%) provide an attractive compact alternative to internal combustion engines for many military applications. They will also expand the possibilities for waste heat recovery applications. The core of the solution we are proposing is a metal/semiconductor nanocomposite that will allow us to modify four intrinsic material properties in order to fabricate

Potential Energy: Potential energy is the stored energy of position possessed by an object. Potential Energy Formula : Potential Energy: PE = m x g x h Mass: Acceleration of Gravity: Height: where‚ PE = Potential Energy‚ m = Mass of object‚ g = Acceleration of Gravity‚ h = Height of object‚ Examples: 1. A cat had climbed at the top of the tree. The Tree is 20 meters high and the cat weighs 6kg. How much potential energy does the cat have? m = 6 kg‚ h = 20
