How far did Amelia Earhart fly? 2,000 miles Who piloted the first non-stop flight across the Atlantic? The First Nonstop Flight Across the Atlantic Lasted 16 Harrowing Hours. John Alcock and Arthur Whitten Brown flew across the Atlantic with the help of a sextant, whisky and coffee in 1919—eight years before Charles Lindbergh’s flight. Who […]

What happen when you perform a cardiovascular activity? Cardiovascular exercise is any vigorous activity that increases heart rate and respiration and raises oxygen and blood flow throughout the body while using large muscle groups of the body repetitively and rhythmically. What is the relationship between physical activity and cardiovascular fitness? What is the connection between […]

Is current directly proportional to voltage? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is relation between voltage and current? […]

What factors influence potential and kinetic energy? Since the state of motion of an object can change with time, the kinetic energy of an object can also change with time. The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to […]

What is the use of Natrium 24? Sodium 24 is used as an electrolyte tracer to follow the path sodium takes in a person’s body to see if their uptake levels are within normal ranges, while sodium 22 is used in nuclear medicine imaging for positron emission tomography. Sodium -24 can also be used in […]

What is difference between paramagnetic and diamagnetic? Atoms with all diamagnetic electrons are called diamagnetic atoms. A paramagnetic electron is an unpaired electron. Diamagnetic atoms repel magnetic fields. The unpaired electrons of paramagnetic atoms realign in response to external magnetic fields and are therefore attracted. Why zinc is diamagnetic? Answer. Answer: Diamagnetic means the orbitals […]

How does photon interact with matter? Photons interact differently in matter than charged particles because photons have no electrical charge. give up their energy via secondary interactions (mostly ionization). The interaction of photons with matter is probabilistic, while the interaction of charged particles is certain. What happens if an incident photon collides with a moving […]

Are there any full blooded aboriginal peoples left 2020? Yes there are still some although not many. They are almost extinct. There are 5000 of them left. There are 468000 Aboriginals in total in Australia in which 99 percent of them are mixed blooded and 1 percent of them are full blooded. What is wrong […]

How do you calculate isothermal compression? It is also worth noting that for ideal gases, if the temperature is held constant, the internal energy of the system also is constant, and so ΔU = 0. Since the First Law of Thermodynamics states that ΔU = Q + W (IUPAC convention), it follows that Q = […]

Is hydrogen peroxide supposed to foam? Hydrogen peroxide does not foam in the bottle or on your skin because there is no catalase to help the reaction to occur. Hydrogen peroxide is stable at room temperature. What is the changing of liquid to a gas called? At a certain temperature, the particles in a liquid […]
