Why does altitude make you lose weight?

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. […]

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 element has 2 protons 2 neutrons?

What element has 2 protons 2 neutrons? Helium What did Chadwick prove? In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons – elementary particles devoid of any electrical charge. For this epoch-making discovery he was awarded the Hughes Medal of the Royal Society in 1932, […]

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. […]

How much force does a falling person have?

How much force does a falling person have? OSHA limits the amount of force that a person should experience during a fall to 1,800 pounds. Forces greater than this can result in internal bleeding, damage, or death. When a personal fall arrest system is used, a shock-absorbing lanyard or fall limiter is the only way […]
