Fairuz Dalilah Binti Abdul Rashid Are We Alone? : Discovering Life on Other Planets Habitable Zone and The Drake Equation A habitable zone‚ which is also known as the Goldilocks Zone‚ is basically a region where there is a probability in finding the extraterrestrial life. The finding is based on the temperature and the pressure of a certain planetary-mass objects. When the temperature is between 273K and 373K‚ there will be presence of water that can support the extraterrestrial life to live in

of operations is a rule to clarify confusion that may occur in an equation that has multiple different operations. This rule of Order of Operations states we must solve a complex equation by complete the operations in this order: Parenthesis‚ Exponents‚ Multiplication‚ Division‚ Addition‚ and Subtraction. We can remember this by this mnemonic: Pink‚ Eyes‚ May‚ Doubt‚ Anyone’s‚ Style. *** This will happen if we take this equation and NOT follow the Order of Operation*** 4+ 2 x 3 = If I did not

Coordinate Systems: A point P is described by three coordinates ‚ in cartesian (x‚y‚z)‚ in cylindrical (r‚ ϕ ‚z)‚ and in spherical (r‚θ‚ ϕ )‚ as shown. A point is also defined by the intersection of three orthogonal surfaces‚ as shown.

Contrary to many people’s thoughts about seasons‚ summer is not due to the Earth being closer to the sun and vice versa for winter (these differences are extremely small). The Earth moves around the sun anti-clockwise in an elliptical orbit‚ with one revolution representing a year (365.256 days). To complete the orbit‚ Earth travels at an approximate speed of 67‚000 miles an hour. While we are orbiting around the Sun‚ we are also rotating around an imaginary axis of the earth‚ with one revolution

Reactions and Equations Science Why should a magnesium ribbon be cleaned before burning in air? Answer Magnesium is very reactive metal. When stored it reacts with oxygen to form a layer magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper to remove this layer so that the underlying metal can be exposed into air. Question 2: Write the balanced equation for the following

THE REFRIGERATION SYSTEM AN INTRODUCTION TO REFRIGERATION APPLICATION NOTE BASIC REFRIGERATION PRINCIPLES If you were to place a hot cup of coffee on a table and leave it for a while‚ the heat in the coffee would be transferred to the materials in contact with the coffee‚ i.e. the cup‚ the table and the surrounding air. As the heat is transferred‚ the coffee in time cools. Using the same principle‚ refrigeration works by removing heat from a product and transferring that heat to the outside air
