A small, jagged particle with a density of 1.2 g/cmº deposits on the ground before afarge, round particle with a density of
0.82 g/cm
Which most likely influences the rate of deposition of the jagged particle?
Please help!!!

they are made of gases.

they have a spherical shape.

they make energy through fusion.

the answer is option a.

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
