What is an example of a secondary source? Common examples of secondary sources include academic books, journal articles, reviews, essays, and textbooks. What are the different types of data sources? Data Source Types Databases. Flat files. Web services. Other sources such as RSS feeds. What are the different sources of data collection? Depending on the […]
What is nitrogen fixation definition?
What is nitrogen fixation definition? Nitrogen fixation is the process by which atmospheric nitrogen is converted by either a natural or an industrial means to a form of nitrogen such as ammonia. In nature, most nitrogen is harvested from the atmosphere by microorganisms to form ammonia, nitrites, and nitrates that can be used by plants. […]
Why is methane the worst greenhouse gas?
Why is methane the worst greenhouse gas? The 20-year global warming potential of methane is 84. That is, over a 20-year period, it traps 84 times more heat per mass unit than carbon dioxide (CO2) and 32 times the effect when accounting for aerosol interactions. Which greenhouse gas traps the most heat? Methane. Methane, the […]
What is the standard interval between contour lines on a map?
What is the standard interval between contour lines on a map? Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. Why do contour lines never cross? Contour lines never cross on a topographic […]
Is a smoker at a higher risk of getting the COVID-19 virus than that a non-smoker?
Is a smoker at a higher risk of getting the COVID-19 virus than that a non-smoker? See full answer Can the COVID-19 survive in drinking water? Currently, there is no evidence about the survival of the COVID-19 virus in drinking-water or sewage. What is the coronavirus disease? Coronaviruses (CoV) are a large family of viruses […]
Can hackers turn your lights off?
Can hackers turn your lights off? According to a report from Check Point, a software security firm, the lights contained a vulnerability that would allow for a hacker to not only turn them off and on but could potentially allow someone to install malware on my computer and network using the lights as a gateway […]
What is the velocity of a body in circular motion?
What is the velocity of a body in circular motion? Since the body describes circular motion, its distance from the axis of rotation remains constant at all times. Though the body’s speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body’s speed and its direction of travel. Can […]
How does volume affect buoyancy?
How does volume affect buoyancy? Buoyancy is created when the contained volume of a certain material (gas or liquid) that is lighter and placed into a heavier surrounding material either gas or liquid. So if the volume of the buoyant (lighter) object is increased then the buoyancy will also increase. How do you calculate buoyancy […]
What are the lines around the nucleus called?
What are the lines around the nucleus called? As the electrons zip around, they can move in any direction, as long as they stay in their shell. Any direction you can imagine — upwards, downwards, or sidewards — electrons can do it. Electrons are constantly spinning in those atomic shells and those shells, or orbitals, […]
What is the best angle for air to glass transition?
What is the best angle for air to glass transition? 56.31° Can the Brewster’s angle occur at the interface from air to glass? The Brewster’s angle can occur at the air/glass interface because there are infinite ways that the incidentand refractive angle will add up to 90°. What will be the Brewster angle for a […]
