in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
