Can you drive in freezing rain? Don’t drive, if you don’t have to. If you are aware of freezing rain conditions, stay home. Even with the reduction of speed, slick conditions like freezing rain just means that you will slide slower across the ice-ridden roads. Is driving with sleet dangerous? One of the reasons it […]
What is magnitude of the image?
What is magnitude of the image? in magnetic resonance imaging, an image formed from the amplitude of the signal, distinct from the phase information. What is the importance of magnitude and phase? Both the magnitude and the phase functions are necessary for the complete reconstruction of an image from its Fourier transform. Figure(1. 5a) shows […]
What is the decline in soil quality caused by improper use?
What is the decline in soil quality caused by improper use? Soil degradation is the decline in soil condition caused by its improper use or poor management, usually for agricultural, industrial or urban purposes. It is a serious environmental problem. Soils are a fundamental natural resource, and are the basis for all terrestrial life. What […]
When an electric current operates a buzzer makes a sound?
When an electric current operates a buzzer makes a sound? Explanation: When a buzzer is attached to a certain circuit and we press the key then the circuit gets complete. As a result, the current will start to flow from the batter or cell and moves towards the buzzer. Thus, buzzer produces sound due to […]
What is the most energy efficient heating system for homes?
What is the most energy efficient heating system for homes? Active solar heating may be the most efficient option for heating your home. Electric resistance heating can be expensive to operate, but may be appropriate if you heat a room infrequently or if it would be expensive to exte… What is the most economical heating […]
Why secondary maxima are less intense than the central maximum?
Why secondary maxima are less intense than the central maximum? Why does the intensity of the secondary maximum become less as compared to the central maximum? Answer: The intensity of light of a secondary maximum goes on decreasing with the order of the maximum. Hence, the intensity of secondary maxima becomes less as compared to […]
How do you measure high temperature?
How do you measure high temperature? Pyrometer, device for measuring relatively high temperatures, such as are encountered in furnaces. Most pyrometers work by measuring radiation from the body whose temperature is to be measured. How do you measure temperature over 100 degrees? Fahrenheit and Celsius are two different scales for measuring temperature. A thermometer measuring […]
Can you drive without airbags?
Can you drive without airbags? It’s not illegal to drive without airbags, if your vehicle was manufactured before 1989. So the question then arises: What happens if you have no airbags and get into a crash? Airbags help slow down the change in momentum and help reduce the forces in a crash. How unsafe is […]
How do people eat in space?
How do people eat in space? Astronauts mainly drink water while in space, but flavoured drinks are also available. Freeze-dried drink mixes such as coffee or tea, lemonade and orange juice are provided in vacuum sealed pouches. The astronauts then add water to the beverage pouch through the pressurised hose and suck the drink through […]
What increases effective population size?
What increases effective population size? One of the things that can influence the effective population size is the sex ratio of the breeding animals. We can estimate Ne using information from a population census or pedigree database about the numbers of males (Nm) and females (Nf) that produce offspring in a generation. How does population […]
