Answer:
A
Explanation:
heat energy is transfered through a hot object touching a cold object
Answer: The half-reactions represents reduction are as follows.
Explanation:
A half-reaction where addition of electrons take place or a reaction where decrease in oxidation state of an element takes place is called reduction-half reaction.
For example, the oxidation state of Cr in
is +6 which is getting converted into +3, that is, decrease in oxidation state is taking place as follows.
![Cr_{2}O^{2-}_{7} + 3 e^{-} \rightarrow Cr^{3+}](https://tex.z-dn.net/?f=Cr_%7B2%7DO%5E%7B2-%7D_%7B7%7D%20%2B%203%20e%5E%7B-%7D%20%5Crightarrow%20Cr%5E%7B3%2B%7D)
Similarly, oxidation state of Mn in
is +7 which is getting converted into +2, that is, decrease in oxidation state is taking place as follows.
![MnO^{2-}_{4} + 5 e^{-} \rightarrow Mn^{2+}](https://tex.z-dn.net/?f=MnO%5E%7B2-%7D_%7B4%7D%20%2B%205%20e%5E%7B-%7D%20%5Crightarrow%20Mn%5E%7B2%2B%7D)
Thus, we can conclude that half-reactions represents reduction are as follows.
Answer:
Thick deposits of sediments carried off of the shelf
Explanation:
The continental rise is a thick deposit of sediments that accumulate between the continental slope and the abyssal plain
A is wrong. The area of land that drops toward the deep ocean basins is the continental slope.
B is wrong. The 75-mile shallow flat area just off coastlines is the continental shelf.
D is wrong. The surf area along coastlines is the surf zone

Answer:
<h2>
0.50 m/s</h2><h2>
</h2>
Explanation:
Velocity = distance over time
where distance = 5.20 m
time = 10.4 s.
velocity = <u> 5.20 m </u>
10.4 s.
= 0.50 m/s
