A 19-m-high and 13-m-long wall under construction and its bracing are shown in the figure above. (Ignore the numbers in the figure; the correct numbers are given in the previous sentence.) The wall is in stable equilibrium without the bracing but can pivot at its base. Calculate the force exerted by each of the 10 braces if a strong wind exerts a horizontal force of 672 N on each square meter of the wall. Assume that the net force from the wind acts at a height halfway up the wall, assume that the braces are all attached halfway up the wall, and assume that all braces exert equal forces parallel to their lengths. Neglect the thickness of the wall.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
