Question

A period of time is usually measured by comparing it with another period of time. For example, a year on Mercury is equal to 88 Earth days. A year on Uranus is approximately 348 Mercury years. According to the passage, the way time is usually measured shows that time is?

A) Absolute and constant
B) Relative and variable
C) Linear and one-dimensional
D) Subjective and unpredictable

Answer 1

Time is measured relative to frames of reference and motion, indicating it is relative and variable, not absolute and constant.

Step-by-step explanation:

According to the passages, the way time is usually measured shows that time is B) Relative and variable. This is evident through the comparison of time measurement on different planets, where a year on Mercury is equal to 88 Earth days and a year on Uranus is about 348 Mercury years. Definitions of a day and a year vary depending on the reference point, such as Earth's rotation, the position of the Sun, or the rotation with respect to distant stars.

The variation in the understanding and measurement of time between planetary bodies and observers demonstrates that time is not absolute but is rather dependent on frames of reference and relative motion.
