Given the values provided:
Natality = 25
Mortality = 24
Immigration = 2
Emigration = 3
The net increase in population (M) can be calculated as follows:
M=Natality−Mortality+Immigration−Emigration
M=25−24+2−3
M=1+2−3
M=3−3
M=0
Based on the given values, the net increase in the population (M) is 0. Therefore, the correct option is (B) 0.
The population size of a village is influenced by several factors: births (natality), deaths (mortality), immigration (individuals entering the village), and emigration (individuals leaving the village). The net increase in population is calculated by considering all these factors.
We are given the following information:
The net increase in population (\(\Delta P\)) can be calculated as:
\(\Delta P = \text{Natality} - \text{Mortality} + \text{Immigration} - \text{Emigration}\)
Substituting the given values:
\(\Delta P = 25 - 24 + 2 - 3 = 0\)
Therefore, the net increase in population is:
0
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
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
