Observe the population growth curve and answer the questions given below:
(a) State the conditions under which growth curve ‘A’ and growth curve ‘B’ plotted in the graph are possible.
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
In an experiment to determine the figure of merit of a galvanometer by half deflection method, a student constructed the following circuit. He applied a resistance of \( 520 \, \Omega \) in \( R \). When \( K_1 \) is closed and \( K_2 \) is open, the deflection observed in the galvanometer is 20 div. When \( K_1 \) is also closed and a resistance of \( 90 \, \Omega \) is removed in \( S \), the deflection becomes 13 div. The resistance of galvanometer is nearly:
The execution of different methods or tools which may include drugs, surgical procedures in either males, females, or both to prevent conception is known as birth control.
There are different types of birth control methods such as;
