How has the economy of canada changed?

4vir4ik [10]

Answer:

The service sector jobs that have increased in importance differ in some significant respects from traditional manufacturing jobs. Service industries have a higher incidence of part-time and temporary workers, rely more on unpaid overtime and make greater use of flexible work arrangements. At the same time, the proportion of workers with at least a university degree is, on average, higher in services than in manufacturing, suggesting that work is becoming more knowledge-intensive. An examination of labour shifts alongside a previous analysis that used Census data to determine the knowledge intensity of different industries indicates that structural change is indeed supporting Canada's evolution towards a knowledge-based economy

A decomposition of labour compensation growth over 1976–79 to 2001–05 resulted in findings that were generally similar to those derived from the shift-share analysis of productivity growth.

Determine the geographic coordinates of St. John's (NL) and Papeete (Tahiti). Calculate the angular distance (in degrees and rad

Allushta [10]

Answer:

Explanation:

Here, geographic coordinates of

St. John's (NL) is latit

The angular distance is 100o

To covert it into radians,

1o = pie/ 180o = 0. 0174444 radians

therefore,

100o =?

multiply 100 with 0. 0174444 we get,

= 1. 7444 radians

Now we have a formula to calculate the distance between these two cities.

Let y is the distance between two cities

Therefore,

Y = (x/360) x 2 x pie x R

Here,

x = angular distance between the cities.

pie = 3. 14

R= radius of earth = 6371km

Hence, by putting these values in the above formula we get,

Y = (100/360) x 2 x 3. 14 x 6371

= (0. 277777) x 40009. 88

= 11113. 82 km
