Answer:

Explanation:

  • From the diagram, tanФ = opp/Adj = 2.4m/7m
  • tanФ = 0.3429. Ф = arctan ( 0.3429 )
  • Therefore, Ф = 18.92°

Given force perpendicular to AC from the diagram = 720N

  • Resolving vertically; PsinФ = 720

a) P = 720/sin18.92° = 2220N = the magnitude of the force P

b) To get component along line AC;

  • resolving horizontally, component along AC = PcosФ
  • = 2220 x cos 18.92° = 2100N

Using selection sort, how many times longer will sorting a list of 40 elements take compared to a list of 5 elements
Hoochie [10]

It will take 8 times more time to sort a 40-element list compared to the time spent on a 5-element list.

We can arrive at this answer as follows:

  • We can see that if we divide a group of 40 elements into groups containing 5 elements, we will have 8 groups.
  • In this case, the time it would take to sort the list of one group of 5 elements would be repeated 8 times so that we could sort all the groups and their elements.

Another way to do this is to divide the number 40 by 5. We would have the number 8 as a result, which indicates that we would need 8 times more time to sort a list of 40 elements, compared to a list of 5 elements.
