B: 210.8 rounded to 210 is totally wrong, and the reason why is because 210.8 rounded to the nearest whole number is 211, not 210. So B is the one with the error (this option is correct) and the other user that said D, is wrong since 18.42 does round to 18.4.
Hope this helped!

<span>The answer to this question would probably be "</span><span>D. The same background radiation was observed coming from all directions of space."
The background radiation here is referring to the Cosmic Microwave Background Radiation, one of the observational evidences of the Big Bang Theory which was discovered by Penzias and Wilson as they were doing some observations with a microwave receiver. </span>
Please READ Newton's first law of motion, and you'll see how nicely it explains that fact.
The answer to this is
<span>A mass on a spring will oscillate vertically when it is lifted and released. The gravitational potential energy increases from a minimum at the lowest point to a maximum at the highest point. ... The total mechanical energy at those points is the sum of the elastic and gravitational potential energies.</span>

Neon is actually: Lithium. And the difference is Lithium reacts readily with water. <span>where Beryllium does not</span>
