Elements in the same column of the periodic table exhibit similar properties (periodicity). Carbon, in Group XIV (14), and elements below it in the same column react in similar fashion. The most similar element to carbon is silicon (Si).
Answer:
P.E = 3.675 J
Explanation:
Given data:
Height of table = 0.75 m
Mass of book = 0.5 kg
Potential energy = ?
Solution:
Formula:
P.E = mgh
g =acceleration due to gravity = 9.8 m/s²
by putting values,
P.E = 0.5 kg× 9.8 m/s² ×0.75 m
P.E = 3.675 kgm²/s²
J = kgm²/s²
P.E = 3.675 J
