V = final velocity
u = initial velocity
a = acceleration
s = displacement
Take downward direction as positive.
v^2 = u^2 + 2as
v^2 = 0.8^2 + 2(1.6)(5.5)
v^2 = 18.24
v = 4.27 m/s
Answer:
Explanation:
Allotropes are the elements that occur naturally in different forms in the nature.
For example Oxygen is in O2 state for breathing air and O3 in ozone layer.
Also C exits as diamond, graphite,coal and other numerous forms in nature.
<span>The atomic number of
a neutral atom is equal to the number of protons and the number of electrons of
the atom. The atomic weight meanwhile is equal to the sum of the number of
protons and number of neutrons. In this case, the atomic number of the atom is 3 and the atomic mass is 7. Hence the element is Lithium, a metal </span>
