Answer:
Option C
A feather falls from one end of a tube to the other inside a vacuum
Explanation:
In conservative force field, which in this case is a vacuum, you expect that there will be no loss of energy to air-friction. Therefore, when a feather falls from one end of the tube to the other side which is a vacuum, we expect no energy loss. Conservative forces are the forces that are path-independent. This implies that in a closed loop, the total work done is zero. Considering the options given, only feather falls from one end of a tube to the other inside a vacuum meets the criteria
Answer:
B)
Explanation:
Given
As the forces are on X and Y-axis. We can see the angle between the forces is 90°
Using vector addition formula. Since the angle between the forces is 90°

Answer:
Testing
Explanation:
Ancient Greek philosophers lived with the ideology to simply contemplate life. This means that their whole life revolved around thinking and questioning everything. This would include creative thinking, because they would sometimes come up with theories which require creativeness. They would often debate with their friends as to why their theory should be accepted or what their opinions were on the matter. More often than not, they argued a lot, and many philosophers went against some powerful people in the community and some were even sentenced to death.
The main process they didn't/couldn't do was the testing. They could never test certain theories because they did not have the means to.
