Jets streams play a key role in determining the weather because they usually separate colder air and warmer air.
Answer: A = atomic number = 12
Explanation: A (atomic number) defines the chemical element. It is the numbervof protons or electrons. Neutron numbers may vary, produving isotopes of differing atomic mass. This isotope has atomic mass 28. The atomic number 12 = carbon. C28 does not really exist. If it could be produced it would be radioactive with an almost zero halflife.
Answer:
C. 7.50g
Explanation:
The percent (%) by mass of a solute in a solution refers to the number of grams contained in 100g of solution by that solute. In this case, 5% by mass of pottasium chloride (KCl) means 5g of KCl is contained in 100g of solution.
Therefore, in 150g of solution, there would be:
5g/100g × 150g
= 0.05 × 150
= 7.50g of KCl solute.
Hence, 7.50g of pottasium chloride would be expected to be collected by evaporating 150.0 g of the solution.
That only 250 warhead are needed to put the earth in nuclear winter
A Tsar Bomba (nuke with highest yield of 100,000 megatons developed by the Russians)in Tokyo results in 12 million dead instantly and a further 5 million in slow death.
Only the supergiants (US,Soviet Union,China,India,Uk,France,Pakistan,Israel and North K) have nukes with a fewer number of countries in the nuclear triad “hub”(US,Soviets,China,India) therefore these posses an unfair disadvantage.
Avearage nuke yield is 100 megatons which can wipe out a whole country.
They are not effective as one would use them unless they want to watch WW3 from their TV.
They produce high amount of radiation when you make them
Once produced they take a long time to dismantle.
I know everything about nukes so don’t hesitate to ask me about the topic:)
