How can I generate electricity cheaply? The IRENA report found that solar and onshore wind are the cheapest energy sources. It states that in 2017 wind turbine prices had an average cost of $0.06 per kWh, and at times dropped to $0.04 per kWh. What is the cheapest power generation? solar power schemes Is using […]
What is the best wattage microwave to buy?
What is the best wattage microwave to buy? A 1,000-watt or 1,200-watt option is the best for most people’s needs, however. It’s enough power to heat or defrost anything from the freezer section thoroughly. Cheaper microwaves with under 700-watts take longer to cook your food efficiently and may struggle to heat things evenly. How do […]
Who is the tallest man on earth in 2020?
Who is the tallest man on earth in 2020? Sultan Kösen Who is the shortest man alive? Chandra Bahadur Dangi Who is the tallest kid in the world? Brenden Adams Born September 20, 1995 Ellensburg, Washington, U.S. Known for Formerly the tallest teenager in the world Height 7 ft 8 in (2.34 m) How tall […]
How do you calculate half-life examples?
How do you calculate half-life examples? The quantity of radioactive nuclei at any given time will decrease to half as much in one half-life. For example, if there were 100g of Cf-251 in a sample at some time, after 800 years, there would be 50g of Cf-251 remaining. After another 800 years (1600 years total), […]
Is a high pressure system Hot or cold?
Is a high pressure system Hot or cold? High pressure systems can be cold or warm, humid or dry. The origin of a high-pressure region determines its weather characteristics. If a high-pressure system moves into Wisconsin from the south during the summer, the weather is usually warm and clear. What do you notice about the […]
What will be the magnetic field outside and inside a long current carrying solenoid?
What will be the magnetic field outside and inside a long current carrying solenoid? Outside the solenoid the magnetic field will be weak and the field lines will curl up to form closed loops. Hence, the magnetic field inside a solenoid carrying current will be the same at all the points. What is the value […]
What is the relationship between absorbance and concentration?
What is the relationship between absorbance and concentration? One factor that influences the absorbance of a sample is the concentration (c). The expectation would be that, as the concentration goes up, more radiation is absorbed and the absorbance goes up. Therefore, the absorbance is directly proportional to the concentration. How do you calculate absorbance from […]
What does miasma mean in Greek?
What does miasma mean in Greek? In Greek mythology, a miasma is “a contagious power that has an independent life of its own. Until purged by the sacrificial death of the wrongdoer, society would be chronically infected by catastrophe.” An example is Atreus who invited his brother Thyestes to a delicious stew containing the bodies […]
Why are telescopes limited?
Why are telescopes limited? The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. Is the human eye diffraction limited? The human eye is close to being fully diffraction-limited, at least for photopic (cone-based) vision at the center […]
Can electrons travel through air?
Can electrons travel through air? In order to create an electrical current, electrons must be ripped off of the air molecules so that they are free to move and form a current. Rather, air displays a complex relationship between the applied voltage and the resulting electrical current traveling through the air. Can current flow in […]
