Will give brainliest how does the angle of the sun affect the climate?
please write in your own words

Depending on the different angles the sun reaches the earth at, the amount of the suns ray may differ per angle. Smaller, more concentrated areas of the suns rays would result in warmer temperatures while areas where sunlight is spread out may have colder temperatures.

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
