A nucleus of carbon 14 has 6 protons and 8 neutrons. The atomic number and mass number of carbon 14 are, respectively, a) 6 and 8
b) 6 and 14
c) 8 and 14
d) 14 and 20
e) 14 and 22

6 and 14 respectively

Explanation:

proton number = atomic number

mass number = proton number + neutron number

since

talk back to him about the sport and show him your expertise or leave the room

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
