What did Japan want in WWII?
What did Japan want in WWII? Faced with severe shortages of oil and other natural resources and driven by the ambition to displace the United States as the dominant Pacific power, Japan decided to attack the United States and British forces in Asia and seize the resources of Southeast Asia. Why did Germany declare war […]
How many hours of sun does a north-facing garden get?
How many hours of sun does a north-facing garden get? You’ll get quite a bit at the height of summer, I should think about 7 hrs a day ime, central England latitude — more if you’re further north. Obviously at the ends of the day (morning, early evening. Good aspect for a conservatory (won’t get […]
Why are mental maps useful?
Why are mental maps useful? Mental maps provide people with essential means of making sense of the world and of storing and recalling information about the patterns of Earth’s physical and human features. Students must build their mental maps to develop detailed understandings of peoples, places, and environments. Who gave concept of mental map? The […]
What are three effects of urbanization?
What are three effects of urbanization? Poor air and water quality, insufficient water availability, waste-disposal problems, and high energy consumption are exacerbated by the increasing population density and demands of urban environments. Strong city planning will be essential in managing these and other difficulties as the world’s urban areas swell. Which of the following is […]
What is the importance of ribosomes?
What is the importance of ribosomes? Ribosomes facilitate the synthesis of proteins in cells (i.e., translation) (see Figs. 1-1 and 1-3). Their function is to “translate” information encoded in mRNA into polypeptide chains of amino acids that make up proteins. There are two types of ribosomes, free and fixed (also known as membrane bound). How […]
How do you say pay attention to detail?
How do you say pay attention to detail? When you are trying to show you are detail-oriented on your resume, be specific about what you have done that proves you are detail-oriented. For example, instead of merely saying “detail-oriented,” try including a statement like “analyzed data to check for errors and inaccuracies.” What type of […]
Why does aluminum foil block WiFi signals?
Why does aluminum foil block WiFi signals? If you’ve ever thought of resorting to aluminum foil to redirect your home’s poor WiFi signal, it turns out you’re not actually that far off the mark. The foil, an electrical conductor, creates a barrier called a Faraday Cage around the phone, blocking the radio signals on which […]
What is the formula for capacitance of a capacitor?
What is the formula for capacitance of a capacitor? The generalised equation for the capacitance of a parallel plate capacitor is given as: C = ε(A/d) where ε represents the absolute permittivity of the dielectric material being used. How can you increase the capacitance of a parallel plate capacitor? The capacitance of a set of […]
What is resonance frequency of LC circuit?
What is resonance frequency of LC circuit? Resonance occurs when an LC circuit is driven from an external source at an angular frequency ω0 at which the inductive and capacitive reactances are equal in magnitude. The frequency at which this equality holds for the particular circuit is called the resonant frequency. How does an LC […]
