There is NOT a difference in speed between a car going forwards at 5 m/s and a car moving backwards at 5 m/s.

Speed is just the rate of change of the position of an object. It is calculated by dividing the change in position (distance traveled) by the time it takes to move said distance.

The distance between the two points is always positive because the direction does not matter.

However, if we are looking for the velocity, the direction DOES matter. In this example, the velocity moving forwards is 5 m/s while the velocity moving backwards is -5 m/s.

In other words:

<em>Speed </em>is looking at the <em>magnitude</em>

<em>Velocity </em>is looking at the <em>magnitude </em><em>and </em><em>direction.</em>

Wegener's theory of continental drift was largely dismissed by the mid-1900s. What new evidence was able to revive this theory,
gavmur [86]

Answer:

<u>C. The coastlines of South America and Africa were similar in shape, suggesting that they shared a common tectonic plate.</u>

Explanation:

  • As suggested by the Alfred Wegener, the plates of the South America and the African plants had a similar geologic history and thus shared a common tectonic boundary and hence validate the proof of the superclass and the drifting of the plates at various time zones.  
  • Thus after the 1960s the plate tectonic theory came into the limelight and was heavily recognized to be fit the works of the drifting of the continental landmasses.

Which reaction would you employ to build a disaccharide from two monomers of glucose?
GenaCL600 [577]

Answer:

D. dehydration synthesis

Explanation:

Dehydration means removing water, and synthesis means building or creating something. Therefore, the synthesis of dehydration is defined as removing water to build something. This process occurs by removing a molecule of -OH (hydroxyl group) and a molecule of -H to form H2O or water. This results in the covalent bonding of two monomers (small molecules) to form a polymer (larger molecule).

Dehydration synthesis uses condensation in the process and when this continues for a long period of time, a long and complex chain is formed, such as those of disaccharide or polysaccharides. It is also responsible for storing excess glucose molecules as well as larger polysaccharides such as starch and glycogen.
