I believe that answer is nitrogen.
This number has 3 sig figs.
1 watt = 1 joule per second = 1 newton meter per second = 1 kg m2 s-3

Answer:</h2>
<u>A. A nuclear power plant</u> produces radioactive wave.
<h2>
Explanation:</h2>
A plant in which a nuclear reactor is used as a source to produce heat is known as nuclear power plant. The heat formed by the reactor is used to form steam which can be used to drive turbines to produce electricity.
The coolant in reactor gets heated by the fission process taking place in the reactor. It is a cyclic process where the steam is condensed and reverted back. A nuclear power plant in active condition produce a small amount of radiation which can be sensed within a radius of 50 miles.
A line from second to home creates a right triangle with 45 degree angles.
This makes the diagonal line the side length of the square multiplied by the sqrt(2)
Second to home = 90sqrt(2) = 127.279 feet ( round answer as needed)
