a) Create a java project named school
b) Add two classes, namely student and lect
c) In student class, create the following methods:
i. calculate_stud_age – This method should take year of birth of the student as a
parameter and calculate and return the student’s age
ii. calculate_ave_mark – This method should take three marks of the student ,
Math, English and Physics marks as parameters and return the average mark.
d) In the lect class, create the following methods:
i. get_name – This method should take a string (name of the lect) and
an integer (experience of the lect in years). This method should
output the name of the Lect together with his designation
based on the years of experiences determined by the following:
Professor – if experience is >= 20 years
Associate professor – if experience is >=15 years
Senior lecturer – if experience is >= 10 years
Associate lecturer – if experience is >=5 years
Junior lecturer – if experience is <5 years

____ AgNO3(aq) + ____K2CrO4(aq) → ____Ag2CrO4(s)+ ____KNO3(aq)
we discussed various approaches to understanding what motivates human behaviour. Two somewhat similar theories have come out of the psychoanalytic and humanistic approaches. Based on Henry Murray’s work within the psychoanalyticperspective, David McClelland proposed that people have three primary motivations: achievement, affiliation, and power. Using a humanistic framework, Edward Deci and Richard Ryan proposed self-determination theory, also suggesting that people have three basic motivations: autonomy, competence, and relatedness.
- In what ways are the three types of motivations proposed by McClelland similar to those proposed by Deci and Ryan? In what ways are they different?
- Which theory do you think provides the better explanation for what motivates human behaviour? Why?
Calculate ∆H for the reaction 2C(s) + H2(g) → C2H2(g) using the following data:
H_2(g) +1/2 O_(2(g))→H_2 O_((l)) ∆H=-286 kJ
C_((s))+O_(2(g))→〖CO〗_(2(g)) ∆H=-394 kJ
C_2 H_2(g) +5/2 O_(2(g))→2〖CO〗_(2(g))+H_2 O_((l)) ∆H=-1 300 kJ
