Answer:
1. This discovery included Pluto in a newly created family of dwarf planets. It also forced the International Astronomical Union to redefine the term planet.
2. The demotion of Pluto to dwarf planet was caused by the discovery of Eris, a minor body that is larger than Pluto. This discovery triggered important events in the history of science. It also proved that there are still many objects to be discovered in the solar system. Therefore, this was a positive development.
3. This discovery was controversial to a small degree because it challenged a widely accepted belief that Pluto was a planet. However, Pluto was discovered less than a century ago, and people showed little resistance to accepting the change.
4.This discovery can be linked to the developments made in astronomy during the Scientific Revolution. It’s somewhat similar to what happened when Copernicus presented his heliocentric theory. He disputed Ptolemy’s accepted theory that Earth was the center of the solar system. Copernicus argued that the Sun was the center and that Earth and the other planets revolved around it. Both discoveries triggered more research in the field of astronomy.
Explanation:
The example asnwers
The magnitude of the force acting on the object is equal to 0.70 Newton.
<u>Given the following data:</u>
To determine the magnitude of the force acting on the object:
The impulse experienced by an object is the product of force and time.
Mathematically, impulse is given by this formula:
Where:
Making F the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Force, F = 0.70 Newton.

<span>the Philippines has emerged as what Carter in January termed “a central part” of the Obama administration’s rebalance, particularly in the security realm. In no small part due to China’s growing assertiveness in the South China Sea, Manila has cemented itself as a key location for America’s military presence; an exemplar of partnering both with Washington as well as its regional allies like Japan and Australia; and an upholder of international principles in the maritime security domain. </span>
