the mass number minus the atomic number
Answer:
Passive solar heating uses building design to utilize sunlight, while active solar heating uses technology.
Explanation:

W, because as time is moving up at a consistent rate the speed is as well, creating the straight line.
Av Speed = total distance / time time = 32+ 46 / 2.7 = 28 m/sec
Av velocity = total displacement / time total = S / t
S = sqrt( 32^2 +46^2) = 56 m
Av Velocity = 56/ 2,7 = 20.75 m/sec
with angle tan^-1 = 0.7 north west ( about 35 degrees north west)
Explanation:
The protons determines the atomic number which helps in identifying an atom of an element
