If the pH of an aqueous solution is increased from 3.5 to 4.3, it means that the solution has become less acidic. The increase in pH value indicates a decrease in the concentration of hydrogen ions in the solution, making it more basic or alkaline.

ترجم حلول Ai The smaller the object, the smaller the surface area will be. This statement is generally true. In most cases, as an object decreases in size, its surface area will also decrease. This is because surface area is directly related to the physical dimensions of an object. For example, imagine a cube that is 1cm in size. The surface area of this cube would be 6 square centimeters. If the cube were to be reduced in size to 0.5cm, its surface area would decrease to 1.5 square centimeters. However, it is important to note that this relationship may not hold true in all cases, as the shape and structure of an object can also affect its surface area. Additionally, certain properties of objects, such as fractals, can lead to more complex relationships between size and surface area.

Two power system A and B are interconnected by a tie line and have power frequency constants Ka and KB per Hz. An increase of load of 500MW on system A causes a power transfer of 300 MW from B to A. If the tie line is then opened, the frequency of system A falls to 49Hz and B rises to 50Hz, find the value of KA and KB.
