Meristematic cells do not show the property of storage of food. Rest of the statements are characters of meristem.

The displacement is the shortest path between initial and final position. Displacement = AC = (Under Root) √AB₂ + BC₂ = (Under Root) √15₂ + 20₂ = 25 m

Displacement is a vector quantity, it means its value can be positive, negative or zero.

We know that, Momentum = mass X velocity P = mv = kg-m/s Or = kg-ms⁻₁ So, SI unit of momentum is kg-m/s.
