Did NASA launch a probe into its atmosphere? What was its name?

Are the 1,000 mph winds sustained or do they deminish at times?

If it is sustained, how can the planet remain in one piece with that much wind?

Only serious theories and/or facts that pertain to these questions will be considered for 'Best Answer'.

I got the equations and the solution, now how do I balance?

•HgCl2 + Na2CO3 = 2NaCl + HgCO3
•No2(Co3) + Pb(No3)2 = Pb(Co3) + No2(No3)2
•No2(Co3) + KI = No2I + K(Co3)
•Pb(No3)2 + Na2(SO4) = Pb(SO4) + Na2(No3)2
•BaCl2 + Na2(SO4) = Ba(SO4) + Na2Cl2
•CuCl2 + No2(Co3) = Cu(Co3) + No2Cl2
•CuCl2 + KI = CuI + KCl2¬

thank you

A project to build a huge machine called the 'Super Conducting Super Collider' that would have explored the nature of matter and energy, was cancelled in 1993. What do you think it would have explored if it had been built. The advancement of human knowledge requires that investments should be made in projects like these. It sure was expensive but it would have cost a fraction of the money that nations invest in weapon systems. What were the reasons for its cancellation.

Show that the given line integral is independent of path.
Then, evaluate the line integral I by finding a potential function f and applying the Fundamental Theorem of Line Integrals.
I=∫(0,0)(1,2)(x+y)dx+(x-y)dy, where (0,0) is the lower bounded point and (1,2) is the upper one

hey guys
I know some one out there knows the answer to this question........
How does concentration affect the enthalphy curve? You can use the enthalphy curve for water as an example. ( I think its also known as the heating curve).
Thanks

On a separate sheet of paper (or computer software program like Word) construct a truth table for the statement below, and determine if the statement is a tautology, a contradiction, or contingent:
p > [~q > (q v ~q)]

Then answer the following questions based on your and number each response so I can be sure which question you are answering:

1. How many rows do you need to complete the proof?
2. What are the truth values for the statement inside the parentheses of the statement which reads: (q v ~q)?
3. State whether the statement is a tautology, contradiction, or contingent and justify your answer.

Then answer the following questions based on your work and number each response so I can be sure of which question you are answering:
1. How many variables are involved in the proof?
2. How many rows do you need to complete the proof?
3. What rows have all true premises?
4. What are the truth values for the fourth row of the proof for each premise and the conclusion?
5. Is the argument valid?
