How many electrons must be transferred to generate a charge of 1 C?
How many electrons must be transferred to generate a charge of 1 C? We know that the charge on an electron is negative, and it is -1.6⨯10-19 coulomb. We need to calculate the number of electrons constituting one coulomb of charge. Total charge required for 1Coulomb. So 1 Columb of charge contains 6 × 1018 […]
What happens when a hot body and cold body are kept in contact with each other?
What happens when a hot body and cold body are kept in contact with each other? Thermal energy is moved from hot spots to cold spots by convection. Convection happens when hotter territories of a fluid or gas ascend to cooler regions in the fluid or gas. Cooler fluid or gas at that point replaces […]
Why is a triple beam balance called that?
Why is a triple beam balance called that? Its name refers to its three beams, where the middle beam is the largest, the far beam of medium size, and the front beam the smallest. The difference in size of the beams indicates the difference in weights and reading scale that each beam measures. How many […]
Is electronegativity affected by effective nuclear charge?
Is electronegativity affected by effective nuclear charge? Electronegativity is how much an atom pulls in electrons. If there are a lot of shielding electrons, outer electrons won’t be drawn towards the nucleus due to the low effective nuclear charge, and so electronegativity will be low. Effective nuclear charge is directly proportional to electronegativity. Does Zeff […]
How much energy is in 1kg of coal?
What can you determine when searching ahead of you?
What can you determine when searching ahead of you? Scanning helps you to see problems ahead that may cause you to change speed or roadway position, such as vehicles and people that may be in the roadway or signs warning of problems ahead. Look ahead –In order to avoid emergency braking or steering, you should […]
Why do guys name their cars girl names?
Why do guys name their cars girl names? One theory is that the habit carried over from men’s habit of calling ships “she” and naming ships after women, most often goddesses in ancient times. Similarly, when men became dependant on motor vehicles, they were an ornament of pride and cared for with great attention by […]
