Where is a oceanic to oceanic convergent boundary? We continue our trip up western North America to find a convergent plate boundary where oceanic crust subducts beneath oceanic crust. North of the contiguous U.S. lies Canada, and north of Canada lies Alaska. A line of volcanoes, known as the Aleutian Islands, is the result of […]
Which is brighter 40W or 60W bulb?
What is the main problem with floating point numbers?
What is the main problem with floating point numbers? The problem is that many numbers can’t be represented by a sum of a finite number of those inverse powers. Using more place values (more bits) will increase the precision of the representation of those ‘problem’ numbers, but never get it exactly because it only has […]
What is the actual mass of 1 u?
Is the normal force conservative?
Is the normal force conservative? The normal force is non-conservative, and therefore has no associated potential energy. The type of work done by the normal force, however, will depend upon the specific situation: Substantial deformation is a signal that the normal force has done measurable negative work (dissipating mechanical energy) on the system. Is tension […]
What increases slow wave sleep?
What increases slow wave sleep? Exercise can improve sleep by reducing sleep latency and increasing slow-wave sleep (SWS). Some studies, however, report adverse effects of exercise on sleep architecture, possibly due to a wide variety of experimental conditions used. Is Slow wave sleep good? Sleep is thought to be important for efficient daytime functioning. Deep […]
What are the factors that cause tectonic plates to move?
What are the factors that cause tectonic plates to move? Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. […]
Which is the correct path of light in a compound microscope?
Which is the correct path of light in a compound microscope? The path of light through a microscope. Modern microscopes are complex precision instruments. Light, originating in the light source (1), is focused by the condensor (2) onto the specimin (3). The light then enters the objective lens (4) and the image is magnified. What […]
Who is most affected by climate change?
Who is most affected by climate change? The Germanwatch institute presented the results of the Global Climate Risk Index 2020 during COP25 in Madrid. According to this analysis, based on the impacts of extreme weather events and the socio-economic losses they cause, Japan, the Philippines and Germany are the most affected places by climate change […]
Como se determina la fuerza electrostatica?
¿Cómo se determina la fuerza electrostática? Ep= V q [=] J La energía potencial se puede definir como la capacidad para realizar un trabajo que surge de la posición o la configuración . En el caso eléctrico de una carga puntual esta ejercerá una fuerza sobre cualquier otra carga y la energía potencial surge del […]
