Answer : Newton's first law of motion (also known as Law of Inertia) describes about the tendency of an object to resist change from its state of rest / motion / direction (inertia).
Whereas, Newton's third law of motion tells us that forces exists in pairs. It talks about the action & reaction forces, which are equal in magnitude but opposite in direction.
In this way, Newton's third law of motion is different from Newton's first law of motion.

The numbers in power of 10 notation would be :
3 trillion is expressed as 3 × 10¹².
Five-thousandths (0.005) are expressed as 5 × 10⁻³.
730,000,000,000,000 is expressed as 7.3 × 10¹⁴.
0.000000000082 is expressed as 8.2 × 10⁻¹¹.
3 trillion:
In standard form: 3,000,000,000,000
In powers of 10 notation: 3 × 10¹²
Explanation: In this number, 3 is multiplied by 10 raised to the power of 12, indicating that it is 3 followed by 12 zeros. This notation is particularly useful when dealing with very large numbers like the national debt or astronomical distances.
Five-thousandths (0.005):
In standard form: 0.005
In powers of 10 notation: 5 × 10⁻³
Explanation: Here, 5 is multiplied by 10 raised to the power of -3, indicating that it is 5 divided by 1,000 (10³). This notation helps represent fractions or very small quantities.
730,000,000,000,000:
In standard form: 730,000,000,000,000
In powers of 10 notation: 7.3 × 10¹⁴
Explanation: In this case, 7.3 is multiplied by 10 raised to the power of 14, indicating that it is 7.3 followed by 14 zeros. This notation simplifies the expression of extremely large numerical values.
0.000000000082:
In standard form: 0.000000000082
In powers of 10 notation: 8.2 × 10⁻¹¹
Explanation: Here, 8.2 is multiplied by 10 raised to the power of -11, indicating that it is 8.2 divided by 100 billion (10¹¹). This notation is useful when working with very small decimal fractions, such as in scientific measurements.
Powers of 10 notation with superscripts provides a clear and concise way to represent numbers across a wide range of scales, from the macroscopic to the microscopic, making it a fundamental concept in scientific notation.

Answer:
No
Explanation:
I don't think the universe has a starting and ending point because the universe is vast and has not been fully discovered. I think that the universe is endless because all of the stars, planets, and galaxy's have yet to be found and the end or start of the universe is also yet to be discovered so I think that the universe could go on forever.
The universe's starting point is believed to be the Big Bang about 13.8 billion years ago, but whether it has an ending point is still unknown.
The question of whether the universe has a starting point and ending point is a topic explored in the field of physics. According to the Big Bang theory, the universe began with a singularity approximately 13.8 billion years ago. However, it is currently unknown whether the universe will have an ending point.
One theory suggests that the universe will continue expanding forever, gradually growing colder and darker. Another theory proposes the possibility of a Big Crunch, where the universe would eventually collapse in on itself. Some scientists also speculate about the possibility of a cyclical universe, where the cycle of expansion and contraction repeats indefinitely.
It's important to note that these theories are still being studied and researched, and our understanding of the universe's origins and potential ending is continually evolving.
