A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)): 
The protection, preservation, and management of ecosystems and natural habitats refers to biodiversity conservation and ensuring that they are healthy and functional.
The protection, upliftment, and scientific management of biodiversity refer to the conservation of biodiversity so as to maintain it at its threshold level and derive sustainable benefits for the present and future generation.
The following are the three main objectives of Biodiversity Conservation-
