How does radiation differ from convection? (104 points) a Radiation can move through empty space to transfer heat; convection cannot.

b Radiation needs a medium in order for heat to transfer; convection does not.

c Radiation requires objects to have direct physical contact; convection does not.

d Radiation transmits heat by circulating particles in an object; convection does not.

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

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
