How does the movement of air work? Movement of air caused by temperature or pressure differences is wind. Consequently, air blows anticlockwise around a low pressure centre (depression) and clockwise around a high pressure centre (anticyclone) in the northern hemisphere (see Figure 3.1). This situation is reversed in the southern hemisphere. What are the three […]

Where does food spend the longest amount of time?
Where does food spend the longest amount of time? After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food […]

How do you find the potential energy of a simple pendulum?
How do you find the potential energy of a simple pendulum? The potential energy, in the case of the simple pendulum, is in the form of gravitational potential energy U=mgy rather than spring potential energy. What is the equation for potential energy? The formula for potential energy depends on the force acting on the two […]

Where is batch reactor used?
Where is batch reactor used? 1 Introduction. Batch reactors are used in a number of industries producing small quantities of high-valued materials such as cell cultivation, polymer synthesis and crystallization. To operate the batch reactor with success, the final quality performance has to maintain with minimum cost. What is the principle of batch reactor? Heating […]
Are hybrid cars expensive to maintain?
Are hybrid cars expensive to maintain? Normally, routine maintenance and minor repairs are no higher on a hybrid than on a regular car. In fact, they may actually be lower. Because hybrids cost more up front than standard cars of similar size, buyers debate whether the higher gas mileage really saves people money. Do hybrids […]
What is the definition of law of conservation of matter in science?
What is the definition of law of conservation of matter in science? According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and kind of atoms after the chemical change as were present before the chemical change. Can you create more matter? In the […]
