Answer:
On April 21, the altitude of Polaris, as viewed from a location in New York State, was measured as 41.3°.
Explanation:
Answer : The time taken by the reaction is 7.856 seconds.
Explanation :
The expression used for second order kinetics is:
![kt=\frac{1}{[A_t]}-\frac{1}{[A_o]}](https://tex.z-dn.net/?f=kt%3D%5Cfrac%7B1%7D%7B%5BA_t%5D%7D-%5Cfrac%7B1%7D%7B%5BA_o%5D%7D)
where,
k = rate constant = 
t = time = ?
= final concentration = 0.13 mole/L = 0.13 M
= initial concentration = 0.25 mole/L = 0.25 M
Now put all the given values in the above expression, we get:


Therefore, the time taken by the reaction is 7.856 seconds.
Answer: circuit B, Circuit A, Circuit B
Explanation:
Edgunity
1) 1 second = 1000000 microseconds
2) 186000 / 1.61 = 115527.9503 Km
3) We use the equation:
Speed = distance / time
4) rearrange for distance by multiplying both sides by time to get;
Distance = speed x time
5) plug in the values:
Distance = 115527.9503 x 0.000001
= 0.1155279503 Km
