b. elevation increases.
c. acceleration decreases.
d. gravity increas
Answer:
As elevation increases, air pressure decreases, molecules spread out, and air temperature cools.
Explanation:
The high point of a transverse wave is called the crest or the peak, which is the point of maximum displacement. It can be observed by viewing a wave from the top or the side, and its height is measured as the amplitude of the wave.
The high point of a transverse wave, such as a light wave, is called the crest or peak. This is the point of maximum displacement or deformation from the equilibrium position in a transverse wave. If one visualizes a wave as a series of high and low points, similar to viewing the ocean waves from above, the crest would be the very top of the wave, whereas the trough would be the very bottom.
Referencing figures 27.4 and 1.25, a transverse wave can be viewed from above and from the side. From the side, one observes how the electric or magnetic fields vary with time. Furthermore, figure 5.5 shows that the amplitude of a wave (the height) is measured from the peak to the trough. This, combined with the wavelength (measured from peak to peak), helps in understanding the wave's properties.

b. False
Answer: True
Explanation:
A chemical reaction in which the oxidation number of an atom, ion or molecule changes due transfer of electrons between two reactants is known as oxidation-reduction reaction or redox reaction. In Redox reaction, the oxidising agent brings oxidation by gaining electrons and reducing it self.
Example:
Zn + Cu²⁺ → Zn²⁺ + Cu
Here, Cu²⁺ is an oxidizing agent which got reduced to Cu .
Thus, the given statement is true.
It's true that in an oxidation-reduction reaction, the oxidizing agent always undergoes reduction. The oxidizing agent is a substance that is capable of oxidizing other substances, meaning it causes them to lose electrons. By taking these electrons, the oxidizing agent itself is reduced.
In an oxidation-reduction reaction, also known as a redox reaction, the statement that the oxidizing agent always undergoes reduction is indeed true. The oxidizing agent is a substance that has the ability to oxidize other substances, meaning it causes them to lose electrons. In taking these electrons, the oxidizing agent itself is reduced. This is due to the principle that in a redox reaction, when one substance is oxidized (loses electrons), another substance must be reduced (gain electrons).
