The country has developed one of the world’s most powerful economies based entirely on imported raw materials. Who is richest country in world? For example, Iceland […]

Who first discovered fission? Lise Meitner Who found nuclear? Enrico Fermi What is the first nuclear power plant in the world? Obninsk Nuclear Power Plant How safe is nuclear? The evidence over six decades shows that nuclear power is a safe means of generating electricity. The risk of accidents in nuclear power plants is low […]

What causes sudden blind spots in vision? Any damage to your retina, such as a detached retina or artery occlusion, is a possible cause of sudden blindness. A detached retina can cause total loss of vision in the affected eye, or it may only result in partial vision loss, making it seem as if a […]

When should I worry about cold feet? You should also call your doctor right away if your feet feel cold but your skin doesn’t feel cold to the touch. This could be a symptom of a neurological condition. Why is my girlfriend so cold all the time? In some people, most often women, the process […]

What are the 3 levers involved in deep squat? The levers that exist in this analysis are the back, the femur, and the shank or lower leg. The levers, as they hinge around the hip and knee joints, form the diagnostic angles used to analyze and discuss the movement. What are examples of second class […]

What is the function of voluntary muscles? Voluntary muscles are the muscles that are under conscious control and can be controlled at will or we can choose when to use them. They are also known as skeletal muscles as they are attached to the bones. Voluntary muscles are responsible for the movement of body parts […]

What should I wear in 20 C weather? 20 – 25 CELSIUS DEGREE In short, light or mixed fabrics for a variable time. KEY PIECES: if the weather is not so good, wear a denim jacket or a trench; if it is sunny, a cardigan or a maxi scarf is better. ACCESSORIES: if there is […]

What is the mass of one electron in grams? The invariant mass of an electron is approximately 9.109×10−31 kilograms, or 5.489×10−4 atomic mass units. On the basis of Einstein’s principle of mass–energy equivalence, this mass corresponds to a rest energy of 0.511 MeV. The ratio between the mass of a proton and that of an […]

Why does O 3 not exist? An electrically-neutral oxygen atom gains two electrons to form an oxygen ion with two negative charges. The ion would thus be highly unstable and potentially readily lose that outermost electron and return to O3− as the ten inner shell electrons seek to get rid of the additional electron. Why […]

When 1kg of ice at 0c is mixed with? 1 kg of ice at 0°C is mixed with 1 kg of steam at 100°C. What will be the composition of the system when thermal equilibrium is reached? Latent heat of fusion of ice = 3.36 × 103 J kg−1 and latent heat of vaporization of […]
