Why do objects in the sky appear to move and change so much?

Answers

Answer 1

Answer:

It depends on the climate and wind speed at the time.

If the climate is hot and no breeze it will move slower.

If it is cold and very windy it will move rapidly.

Team Kyoto and Team Copenhagen are engaged in a fierce game of Tug of War. Team Kyoto pulls to the left with a force of 5000N and Team Copenhagen pulls to the right with a force of 5000N. Explain what net force will be and in which way (if any) the rope will accelerate.


helpppp due in 20 mins no links pweysss

Answers

Answer:

net force will be 0N and the rope will not accelerate.

Explanation:

to calculate net force, you need to find the difference between the two forces, which would be 5000N - 5000N = 0N

since there is no net force, there is no movement of the rope.

i know it's been more than 20 minutes but i still hope this helps! :D

After you cross the finish line, you slow down and come to a stop, breathing hard. It takes you 10 seconds to come to a stop. What is your acceleration?

Answers

Acceleration = (change in speed) / (time for the change)

Acceleration =  -- (speed as you crossed the finish line) / (10 seconds)
