Answer:

1) 3.1 m/s

2) 7 m/s

Explanation:

Distance due north = 80 m

Distance due south = 30 m

Distance between north and south = (80 - 30) m = 50 m

Total time = (12 + 4) sec = 16 sec

1) Average speed = 50/16 = 3.1 m/s

2) Average velocity = Total distance/total time = (80 + 30) m/16 s = 110/16 = 7 m/s

If a car used 260.000 W of power to complete a race in 15 s. how much work did the car do?
marta [7]

Work done by the car is 3900 J

Explanation:

  • Power and work are related by the equation, Power = Work Done/Time
  • Power is the rate at which work is done.
  • Here, the car uses power of 260 W and time taken is 15 s.

Work Done = Power × Time

                   = 260 × 15 = 3900 J

Which of the following is not an example of natural climate change?
wlad13 [49]

(c) is the correct choice.

El Nino (a), Earth's orbit (b), and solar energy output (d) are all "natural" occurrences.  You can't do a thing aboutum.

Fossil fuels ... or, more precisely, humanity's use of vast quantities of fossil fuels as a convenient source of huge quantities of energy ... and the subsequent increase of Carbon Dioxide in the planet's atmosphere, is not the result of "natural" processes.  It's the result of human efforts to <em>alter and control</em> Nature, through <em>artificial</em> processes.

What is a disadvantage of shared decision-making?
Snezhnost [94]
The disadvantages of shared decision making are:
Adopting a wrong advice from a member can lead to a big risk to the company and the business. 
Further, increased number of advice also confuses the person, about which to follow and which to ignore. 
There is also diffusion of responsibility and lowered efficiency.
