How fast was the ""the thing"" that was heading for the submarine group?

130.0000433 knots = 66.8778 m/s

Explanation:

"the thing" was a submersible th was at released from the Benthic Explorer and splashes into the water to answer the distress call of a sunk submarine. The thing moved at a velocity of 130.0000433 knots.

since electrons are negative the answer is neagtaive

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
