The growth of the minimum hourly wage in a factory from 1940 to 1990 is shown in the table. Find the longest period for which the minimum wage remained constant. Year 1940 1945 1950 1955 1960 1965 1970 1975 1980 1985 1990 Minimum hourly wage..

The graph shows the relationship between Annie's earnings and the number of hours she works overtime. Why does the graph intersect on y -axis? => Annie has to pay initially $30 to the company. or Annie works minimum 30 hours. or Annie′s daily wage is $30. or Annie′s ..

A function is said to be monotonic if it is either increasing or decreasing but not both in a given interval. Consider the function The given function is increasing function on R. Therefore it is a monotonic function in [0,1]. It has its minimum value at x = 0 which is equal to f ..

Cellular respiration is common to all organisms - plants or animals. However, the external respiration, that is, the mechanism of gaseous exchange is different for different organisms. In plants, it is through pores over the body surface. In animals, the various ways of gaseous exchange are also ca..

It can be summarized that the spontaneous processes occur because of the two tendencies: (i) Tendency of a system to acquire a state of minimum energy. (ii) Tendency of a system to acquire a state of maximum randomness. The overall tendency for a process to take place by itself is called..

In case of solutions showing positive deviation from Raoult's law, at one of the intermediate compositions, the total vapor pressure is the highest and the boiling point is the lowest. Similarly in case of solutions showing negative deviations from Raoult's law, at one of the intermediate compositi..

The lateral pressure that the blood exerts against the walls of the blood vessels is called blood pressure. It is caused by a) contraction of the ventricles b) resistance to the passage of blood through arterioles and capillaries. The pressure existing in the arteries is called arterial blood ..

The minimum amount of energy required to emit electrons from a metal surface is called the work function or threshold energy of that metal. The number of electrons emitted per second i.e. the rate of emission depends upon the material of the surface temperature of the surface area..

(a) Center of gravity in loading a ship When a ship floats in the water the forces of buoyancy and gravity balance each other because they are equal. The following three diagrams show how loads affect the center of gravity and stability of a ship. A fully loaded ship [figure (a)] brings the c..

Pressure - When a force is applied on a surface in a direction perpendicular to the surface, the force is called thrust. Pressure on a solid surface is the thrust per unit area of the surface. Pressure is a scalar quantity. The SI unit of Pressure is N m - 2 or Pascal (Pa) Pressure varies..
