Even when bullets of the same ammunition are fired from the same gun, the bullets are generally not a one hundred percent match for each other

true is the answer

HOPE THIS HELPS :)

The correct answer is True.

Explanation:

Bullets usually do not match one hundred percent with each other when fired from the same weapon. The reaction in the bedroom where the hammer hits the bullet causes a deformation, which caused instability in its trajectory. This reaction is violent and does not always occur in the same way.

Have a nice day!

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
