(iii) Why oil floats in water? (b)The density of two liquids (A and B) is given as 1000kg/m' and 600kg/m' respectively. The two liquids are mixed in certain proportion and the density of the resulting liquid is 850kg/m'. How much of liquid B (in grams) does a lkg of the mixture contain? Assume that the volume of the two liquids is addictive when mixed. 5. (a) (i) State the applications of hydraulic press. (ii) Dams are constructed thicker at the bottom than the top. Give reasons. (b) (i) Describe two experiments to show that exert pressure. (ii) Explain why tracks which carry heavy loads have many wheels. (iii) If the mercury barometer is 75.58 cm at the base of the mountain and 66.37cm a the summits. What is the height of the mountain? 6. (a) (i) What is regulation?​

wavelength divides in half and speed stays the same.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

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
