Why does altitude make you lose weight? What causes weight loss at high altitudes? Many studies have looked at climbers at high altitudes and, expectedly, increased energy expenditure due to increased physical activity can contribute to some of their weight loss. Does altitude affect sleep? Sleep Disturbances Trouble sleeping is quite common at high altitude. […]
How do you calculate maximum power transfer?
How do you calculate maximum power transfer? Condition for Maximum Power Transfer Therefore, the condition for maximum power dissipation across the load is RL=RTh. That means, if the value of load resistance is equal to the value of source resistance i.e., Thevenin’s resistance, then the power dissipated across the load will be of maximum value. […]
Which forest layer has the greatest amount of net primary productivity?
Which forest layer has the greatest amount of net primary productivity? Basic ideas – NPP in terrestrial ecosystems Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. The physical environment favours vast photosynthetic output and high growth rate. Which biomes are most affected by humans? Tropical dry forests and temperate […]
How much energy is used in photosynthesis?
How much energy is used in photosynthesis? The part of the solar spectrum used by plants has an estimated mean wavelength of 570 nm; therefore, the energy of light used during photosynthesis is approximately 28,600/570, or 50 kcal per einstein. What percentage of sunlight is used in photosynthesis? 3 percent What organisms use energy for […]
What is a chain reaction simple definition?
What is a chain reaction simple definition? 1a : a series of events so related to each other that each one initiates the next. b : a number of events triggered by the same initial event. 2 : a self-sustaining chemical or nuclear reaction yielding energy or products that cause further reactions of the same […]
What is an example of a terrestrial food chain?
What is an example of a terrestrial food chain? Well, for starters, a food chain is a series of interconnected feeding relationships among different species in an ecosystem. With this in mind a common terrestrial food chain example is grass-grasshopper-snake-hawk. Primary producers, which include plants, are at the bottom (or base) of the food web. […]
What are the four basic earth systems?
What are the four basic earth systems? Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air). Which is the largest system on earth? geosphere How […]
What is the effect of temperature on the viscosity of liquids?
What is the effect of temperature on the viscosity of liquids? The result is that liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same. What is viscosity how it varies with temperature? In general, the viscosity of […]
What would happen if there was no cryosphere?
What would happen if there was no cryosphere? In the Arctic, the decline of the cryosphere is affecting fundamental biological cycles like the reproduction of carbon-storing plankton. And it may also be affecting the jet stream, making weather more extreme across the Northern Hemisphere. Will there be another ice age? Researchers used data on Earth’s […]
Can a TV show make you depressed?
Can a TV show make you depressed? A study in Preventative Science Reports found elevated depression levels when people spent more time on computers and watching TV. In fact, those who spent more than four hours each day staring at a screen were about twice as likely to have depression. Is binge watching bad for […]
