What age group is most suicidal?

What age group is most suicidal? The NVDRS 2015 data showed that, among men of all races, men over 65 were the most likely to die of suicides (27.67 suicides per 100,000), closely followed by men 40–64 (27.10 suicides per 100,000). Men 20–39 (23.41 per 100,000) and 15–19 (13.81 per 100,000) were less likely to […]

Is electric potential a scalar?

Is electric potential a scalar? Electric force and electric field are vector quantities (they have magnitude and direction). Electric potential turns out to be a scalar quantity (magnitude only), a nice simplification. Is electric potential energy? Electric potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated […]

What is happening in the Calvin cycle?

What is happening in the Calvin cycle? The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight. What happens during carbon fixation? Carbon […]

What are the different sources of energy?

What are the different sources of energy? Different Sources of Energy Solar Energy. The primary source of energy is the sun. Wind Energy. Wind power is becoming more and more common. Geothermal Energy. Source: Canva. Hydrogen Energy. Tidal Energy. Wave Energy. Hydroelectric Energy. Biomass Energy. How bad is cotton for the environment? Since cotton is […]

How do you kill germs on your hands?

How do you kill germs on your hands? Washing hands with soap and water is the best way to remove all types of germs and chemicals. If soap and water are not available, use an alcohol-based hand sanitizer with at least 60% alcohol. How long do germs live on hands? Flu germs live for about […]

What is the value of absolute pressure?

What is the value of absolute pressure? Absolute Pressure Defined A full vacuum has an absolute pressure reading of 0 PSIA and average barometric pressure at sea level is ~14.7 PSIA. When measuring gauge pressure, current atmospheric pressure is the baseline and is therefore read as 0 PSIG. What does absolute pressure depend on? Pressure […]

Can an object be heavy but not dense?

Can an object be heavy but not dense? An object, such as a sailboat, may be very heavy, but the sailboat is not dense because its mass is spread out over a large volume. Heavy objects sink and light objects float. How can I learn real magic at home? 6 Tips for Beginner Magicians Learn […]

What produces a reverse fault?

What produces a reverse fault? Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall, you have a reverse fault. Reverse faults occur in areas undergoing compression (squishing). How do faults affect Earth’s surface? Earthquakes occur on faults. A fault is a thin zone of crushed rock […]

Who invented quantum theory?

Who invented quantum theory? Max Planck Why did Einstein disagree with quantum mechanics? Einstein’s opponents thought he simply didn’t understand quantum mechanics – but he knew the problem was deeper. Quantum entanglement of two particles means – bear with me here – that the quantum wave function describing them cannot be mathematically factorised into two […]
