1.        En el último campeonato, Ruth Beitia (72 kg) consiguió una marca de 1,96 m en salto de altura. Supongamos que, cuando estaba a 1,90 m, llevaba una velocidad de 3 m/s. En ese punto, ¿es mayor la energía potencial o la energía cinética? Calcula la energía mecánica.​

i'm not sure

explanation:

i'll try whatever you got

ok whats the question if not i cannot you i need question and need a thing to answer

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
