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 flower structure comprises four major parts or whorls—known as the calyx, corolla, androecium, and gynoecium.
Flowers come in a range of sizes and shapes, but their anatomy, in general, is the same: sepals, petals, stamen, and carpel. A whorl, or circular positioning, is created by arranging these parts in a circular pattern.
Flowers come in various forms:
