Molecules and polyatomic ions are formed by covalent bonds.
The net force = sum of all forces acting on the body
If we take left side as -ve and right side as +ve,
then,
The net force here would be equal to,
10N + (- 3N)
= 7N.
Therefore, a net force of +7N ( + indicates it's moving towards right) is acting on the book of mass 2kg.
Answer:
oxygen combines with small molecules. energy is released and it happens in the cytoplasm
Explanation:
D. Unbalanced forces are acting on it.
