Answer:

Innovations in transportation and communication technologies has actually changed the way we think about distance and time

Explanation:

Transportation and communication were part of the major challenges humanity was facing in time past, the distance between places was seen as a barrier, it delayed many things, communication inclusive because of the lengthy time involved in sending messages, goods and services from one place to another, this gave birth to invention of various means of getting these major activities (that man can not do without) done without wasting much time. Ever since then man has began to see distance and time from a completely different angle, things that will take months to get done because of the great distance in time past can actually be carried out today in a couple of seconds.

If a storm is 7.5 kilometers away, how much time is expected between observations of lightning and thunder? Round your answer to
Svetlanka [38]

Answer:

22.5 s is the correct answer to the given question .

Explanation:

Given that

d=7.5km=7.5\times 10^3 m

For light:

We know that speed of light c

c=3\times 10^8 m/s

We know that

Distance = Speed \times timed=C\time tt=\dfrac{D}{t}t=\dfrac{7.5\times 10^3}{3\times 10^8}\ st=2.5\times 10^{-5}st=0.025 ms

For thunder :

Speed of sound ,v=332 m/s

Time\  taken\  by\  sound \\t\’=\dfrac{7500}{332}=22.59 s

Therefore the difference between time is given as follows

\Delta t= t' - \ t=22.59-2.5\times 10^{-5}=22.59 s

22.5 is the answer

WILL GIVEE BRAINLIEST ANSWER!!!!
Licemer1 [7]

Answer:

People have been ringing the death knell for email on and off for a few years now. But should we be listening?

The latest peal came from French IT company Atos, which declared that it would phase out internal emails by 2013. And for reasons we’ll all recongize: too much time spent dealing with too many emails, of which too few are useful and too many are spam. CEO Thierry Breton said his staff would instead use good old face-to-face communication, as well as instant messaging (IM) and social media tools.

The function below takes two numeric parameters. The first parameter specifies the number of hours a person worked and the secon
Triss [41]

Answer:

def calculate_pay(total_worked_hours, rate_per_hour):

   if total_worked_hours > 40:

       return (40 * rate_per_hour) + ((total_worked_hours - 40) * 2 * rate_per_hour)

   else:

       return total_worked_hours * rate_per_hour

Explanation:

  • Create the calculate_pay function that takes 2 parameters.
  • Inside the function check whether the total_worked_hours is greater than 40 and then return the pay by calculating with the help of formula for work over 40 hours.
  • Otherwise return the pay by multiplying the total_worked_hours with rate_per_hour.
