Answer:
0.182 m/s
Explanation:
m1 = 30,000 kg, m2 = 110,000 kg, u1 = 0.85 m/s
let the velocity of loaded freight car is v
Use the conservation of momentum
m1 x u1 + m2 x 0 = (m1 + m2) x v
30,000 x 0.85 = (30,000 + 110,000) x v
v = 0.182 m/s
Answer:
well its simple the worker wouldn't actually be working
The valence electrons are the electrons in the outermost electron shell of an atom.
Explanation:
The number of electrons in an atom's outermost valence shell governs its bondingbehaviour.
That is why elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table.
Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell, corresponding to the electron configuration <span><span>s2</span><span>p6</span></span>.
This tendency is called the octet rule, because the bonded atoms have eight valence electrons.
