Answer:
Explanation:
Polonium is not flammable, although highly reactive and can reach temperatures of up to 500°C
Answer: No
Explanation:
Electrons have negative charge. It's charge can be decimal because it's about 1.6*10-19 But number of electrons passing through a metal cannot be a decimal number. If you use Q = ne
Q - total charge
e - Charge of an electrone
n - Number of electrons
You might get decimal value for n but it doesnt mean that it shoud have decimal value . Then you have to get nearest less digit value for answer. We cant divide electrons in to pieces
do not last as long as pure gold
much more valuable than pure gold
much softer than pure gold
The carpet is more likely to accumulate excess electric charge (static electricity) over time when there is no good way for it discharge. The dry air, as was said, insulates the carpet and makes it prone to such accumulation. This is less the case with humid air that allows the carpet to continuously discharge a portion of its electric charge over time and thus spares us--the walkers--a minor shock.
Dry air is a better electrical conductor than humid air, which is why you are more likely to receive a shock after walking across a carpet when the air is dry compared to when the air is humid.
The reason you are more likely to receive a shock after walking across a carpet when the air is dry than when the air is humid is because dry air is a better electrical conductor than humid air. When the air is dry, it has a lower field strength, meaning that it takes a smaller voltage to create a spark. On the other hand, humid air breaks down at a lower field strength, so it takes a larger voltage to create a spark. This is why you are more likely to get a shock on a dry day.
