Answer:
hydrogen chloride...........
Answer:
Explanation:
Since 
, we calculate the resistance rate by deriving this formula with respect to time:
Deriving what is left (remember that 
):
So we have:
Which for our values is (the rate of <em>I(t)</em> is decreasing so we put a negative sign):
For astronomical objects, the time period can be calculated using:
T² = (4π²a³)/GM
where T is time in Earth years, a is distance in Astronomical units, M is solar mass (1 for the sun)
Thus,
T² = a³
a = ∛(29.46²)
a = 0.67 AU
1 AU = 1.496 × 10⁸ Km
0.67 * 1.496 × 10⁸ Km
= 1.43 × 10⁹ Km
Answer:
What is a Pure Substance?
Explanation:
It is something which cannot be divided into parts by physical means, as it's all made up of the same thing. Pure substances are either elements or compounds. Elements can NOT be separated into other types of matter (physically or chemically).
I think comets because they are small and they are composed of ice or water. Hope it helps :)
