Kamal is experimenting with an electron beam. He brings a metal bar close to the beam. The path of the beam does not change. What can be said about this metal bar?
Select all that apply.
-The metal bar may be magnetic
-The metal bar is not electrically charged.
-The metal bar may be electrically charged.
-The metal is not magnetic

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great 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
