What is the potential difference between points? Potential difference is the energy used between two points in a circuit, therefore it is measured between two points either side of a component. We describe this as the potential difference measured across a component. What is mean by saying that the potential difference between two points is […]
How does a dipole magnet work?
How does a dipole magnet work? In Summary. The dipole magnets are used to bend the path of the electrons as they travel around the ring. Charged particles travelling in a magnetic field change direction. The stronger the current applied to the electromagnets, the more the electron beam is bent. Why are magnetic dipoles important? […]
What is the name for the imaginary line at 0 degrees longitude?
What is the name for the imaginary line at 0 degrees longitude? prime meridian What is the latitude line called? parallels What are the 5 latitude lines? Important lines of latitude: the equator (0°) the Tropic of Cancer (23.5° north) the Tropic of Capricorn (23.5° south) the Arctic circle (66.5° north) the Antarctic circle (66.5° […]
Do radio waves pass through our bodies?
Do radio waves pass through our bodies? Infrared light and radio waves We can feel the heat of infrared light because its energy is absorbed mostly by the skin. On the other hand, we cannot feel radio waves because these emit their energy deeper in the body, under the heat-sensitive cells of the skin. How […]
Why do bodies move in circular orbit?
Why do bodies move in circular orbit? Explanation of how objects under the influence of gravity move in orbits. A body in uniform circular motion undergoes at all times a centripetal acceleration given by equation (40). According to Newton’s second law, a force is required to produce this acceleration. What is the energy of orbiting […]
What limiting factor was Hurricane Katrina?
What limiting factor was Hurricane Katrina? density-dependent factor What are the 3 limiting factors? In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. What limiting factors affect human populations? […]
Where does the other 90% of energy go in an energy pyramid?
Where does the other 90% of energy go in an energy pyramid? Trophic Levels and Energy This is represented by the ecological pyramid in Figure below. What happens to the other 90 percent of energy? It is used for metabolic processes or given off to the environment as heat. What does an energy pyramid show? […]
Is solar wind visible?
Is solar wind visible? First proposed in the 1950s by University of Chicago physicist Eugene Parker, the solar wind is visible in the halo around the sun during an eclipse and sometimes when the particles hit the Earth’s atmosphere—as the aurora borealis, or northern lights. … How does solar wind affect humans? What is the […]

What comes to your mind when you hear the word humanities? When you hear the word “humanities,” what is the first thing that comes to mind? “Human nature, people, relationships, understanding others.” What is a BA in Humanities? More specifically, what is a BA in Humanities Studies? The humanities include the study of human society […]
What are the first signs of an approaching warm front?
What are the first signs of an approaching warm front? The first signs of an approaching warm front are the appearance of high, thin, wispy cirrus clouds. As the front nears, the clouds will become lower in the sky and be thicker, since there will be more air at lower elevations from which to condense […]
