Potato family (Solanaceae) has the following key characteristics:
Thus, the floral formula of plants in the potato family (Solanaceae) is ♀, K₅, C₅, A₅+₁, G₂, as given in option (B).
The correct answer is: (B) ⚥, K(5), C5, A5, G(2).
The floral formula of a plant belonging to the potato family (Solanaceae) is represented as:
These characteristics are typical of the flowers in the Solanaceae family, which includes important plants like potato, tomato, and tobacco. The floral formula represents the arrangement and number of parts of the flower.
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 \( g = 10 \, \text{m/s}^2 \)):
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
