What does light mean? Light is one of the most universal and fundamental symbols. It is the spiritual and the divine, it is illumination and intelligence. Light is the source of goodness and the ultimate reality, and it accompanies transcendence into the Nirvana of Buddhist doctrine. What does light mean in life? It may mean […]
Is friction a form of mechanical energy?
Is friction a form of mechanical energy? The mechanical energy of the system remains constant provided there is no loss of energy due to friction. The energy would transform to kinetic energy when the speed is increasing. The mechanical energy of the system increases provided there is no loss of energy due to friction. Is […]
Which metal oxides is easiest to decompose on heating?
Which metal oxides is easiest to decompose on heating? The simplest kind of decomposition reaction is when a binary compound decomposes into its elements. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. Mercury(II) oxide is a red solid. When it is heated, it decomposes into mercury metal and oxygen […]
What is the reaction force that propels a rocket forward?
What is the reaction force that propels a rocket forward? As these gases are pushed out in one direction, there is a reaction force that pushes the rocket in the other direction. This reaction force is called thrust. What is the difference between space shuttles and other rockets? The space shuttle launched like a rocket. […]
Why is frost shattering climate related?
Why is frost shattering climate related? Freeze-Thaw Weathering: also called frost-shattering as it occurs in cold climates when temperatures are often around freezing point and where exposed rocks contain many cracks. As the water turns into ice it expands and exerts pressure on the surrounding rock, causing pieces to break off. What is the meaning […]
What is the ratio of velocity to speed?
What is the ratio of velocity to speed? The displacement of the body in given time is always equal to or less than distance covered, because, velocity is displacement per unit time and speed is distance covered per unit time, therefore, ratio of magnitude of velocity and speed is always equal to or less than […]
What kind of information does a life cycle cost LCC analysis provide?
What kind of information does a life cycle cost LCC analysis provide? Performing a life-cycle cost analysis (LCC) gives the total cost of a lighting system—including all expenses incurred over the life of the system. What is lowest life cycle cost? Lowest life-cycle cost (LCC) is the most straightforward and easy-to-interpret measure of economic evaluation. […]
What will be the momentum of a stone having mass of 10 kg?
What are the 2 Equations for electrical energy?
What are the 2 Equations for electrical energy? If voltage, (V) equals Joules per Coulombs (V = J/C) and Amperes (I) equals charge (coulombs) per second (A = Q/t), then we can define electrical power (P) as being the totality of these two quantities. This is because electrical power can also equal voltage times amperes, […]
