Answer:- The speed of the satellite is 7.6
.
Solution:- It's a unit conversion problem that could be solved using dimensional analysis which is also known as train trail method.
The given speed of the satellite is 17000 miles per hour and we are asked to convert it to kilometers per second.
given:
1 Kilometer = 0.62 mile
1 hour = 3600 second
Let's use this given info and plug in the values to make the set up as:
![17000\frac{mile}{hour}(\frac{1 kilometer}{0.62 mile})(\frac{1 hour}{3600 second})](https://tex.z-dn.net/?f=17000%5Cfrac%7Bmile%7D%7Bhour%7D%28%5Cfrac%7B1%20kilometer%7D%7B0.62%20mile%7D%29%28%5Cfrac%7B1%20hour%7D%7B3600%20second%7D%29)
= 7.616
We round the answer to two significant figures, since the given number(17000) has only two significant figures.
Hence, the speed of the satellite is 7.6

Cl03 is a polyatomic ion with a charge of -1. So 2 of those brings that charge to -2. Ca=+2. So Ca=+2 and (Cl03)2= -2. This would balance out the equation. The final result would be Ca(ClO3)2
Answer:
The answer is A
Explanation:
Wavelength is the distnce between the peak or crests in a wave.
I think the major difference is that 0.5 is exactly equal to a half. The other 0.555555 is equal to a half plus five hundredths plus thousandths plus five ten thousandths plus five hundred thousandths, plus five millionths and so forth; and therefore it is greater than 0.5. In other words 0.555555 is called a recurring decimal.
