C.) An explanation for a physical phenomenon, an explanation that hasn't been tested yet.
A) The pieces will repel because the cut end of the top magnet is not a magnetic pole.
B) The pieces will attract because the cut end of the top magnet is not a magnetic pole.
C) The pieces will repel because the cut end of the top magnet is a south pole.
D) The pieces will attract because the cut end of the top magnet is a north pole.
The answer to this problem is "OPTION C" i.e. The pieces will repel because the cut end of the top magnet is a south pole.
A magnet as a collection of tiny magnets, called magnetic domains. Each of these domain reinforces the magnetic fields of the other domains and hence the net magnetic field of magnet is generated. Each one of these domains have a tiny north and south pole. If you cut a magnet in half (along the line suggested in the problem), the newly cut faces will become the new north or south poles of the divided parts.
Answer:
c
Explanation:
Answer: To keep it basic start with temprature and inhibitors such as drugs that slow enzymes
surface area, temperature, concentration, and the presence of catalysts and inhibitors
Explanation:To slow down a reaction, you need to do the opposite. Factors that can affect rates of reactions include surface area, temperature, concentration, and the presence of catalysts and inhibitors. Temperature - Changing the temperature of a chemical reaction also affects the reaction rate.
Answer:
In driving, changes by fractions of a second in reaction time may mean the difference between a collision or the avoidance of one. On the road, distractions, speed, driving experience, and physical and cognitive fitness can seriously affect reaction times.

b. Physicists develop mathematical equations to determine its physical nature.
c. The Big Bang theory provides the scientific guidelines to enable its study.
d. Scientists are able to gather samples from NASA.
Answer: a. The cosmological principle makes assumptions that provide scientific guidelines to enable its study.
Explanation:
Scientists cannot physically test their ideas about the origin of the universe but they use cosmological principles to study. Some aspects of the assumptions made on the basis of cosmological principle can be tested. Whatever was formed at the origin of the universe is present around us. Studies are made on them and conclusions are drawn.
Cosmological principle states that on larger scale, the universe is homogeneous and isotropic. This means in which ever direction we look, its the same and there is no preference to any particular direction to make observations.
There are numerous theories associated with the origin of the universe but none can be proved. The theories can only be studied based on the assumptions made using the cosmological principle.
