Newton’s ideas on physics “won”, and aristotle’s ideas were kicked out of science and over into history. why?
mestny [16]
Basically, Newton's ideas matched up better with experiments and observations about the natural world than Aristotle's did. Newton gave a rigorous mathematical framework that made very specific predictions about our world, while Aristotle in general made more comparative laws, that even when true were less useful than the certainty Newton's laws gave us. Many of Newton's laws have been found to be at least partially incorrect now, for instance his laws of motion fall apart at speed nearing the speed of light, his laws of gravity fall apart when talking about more than two objects and in the presence of large gravitational fields that are close together, and Newton's law of cooling is just untrue in general (though can make some approximations in narrow temperature ranges).

A hot air balloon travels 18 kilometers west and then travels 50 kilometers east. What is the current position of the hot air ba
Firlakuza [10]

Answer:

32 km east

Explanation:

In order to find the final position of the balloon, we need to calculate its total displacement.

We have:

- Displacement towards west: 18 km

- Displacement towards east: 50 km

The two vectors are on the same line: this means that we can simply add them together (taking into account the proper direction) to obtain the total displacement.

Taking east as positive direction and west as negative direction, we have:

d = 50 + (-18) = 50 - 18 = 32 km

And since it is positive, it means that the final position of the balloon is 32 km east from its initial position.
