Answer:The answer is B
Explanation:
There is less water lost due to evaporation and therefore more available to plants. Mulch and minimum tillage results in twice as much available water as does deep tillage. This is an immediate benefit. We are looking for future benefits: less runoff and erosion, more soil stays in place, the soil is more fertile, and farmers use less fossil fuels.

Answer:
the rate slow down
Explanation:
there is less kinetic energy in the system so fewer molecules will have the required energy to overcome the activation energy barrierv
Answer:
this is the reason why scientists opt to transmit data at lower frequency instead of electromagnetic even it can carry more data at a higher frequencies is because using higher frequencies of electromagnetic spectrum travel shorter distances but have higher data carrying capacity.So this physical characteristic of electromagnetic waves limits the range and availability of frequencies for sending information.
Explanation:
Communication refers to the process of conducting and obtaining information in the form of signals. The electromagnetic waves are used by the high technology communications systems, and there are different kinds of electromagnetic waves, which are utilized like microwaves, infrared, radio waves, and others.
However, there are some of the limitations with the applications of electromagnetic waves:
1. Due to a confined number of broadcast frequencies, the application of transmitters must be restricted in a certain manner or they will lead to interference.
2. The physical features like buildings and mountains can interfere or prevent certain transmissions.
3. In the air, the signals can be misleaded due to atmospheric conditions and the signals from the space are at certain occasions get distorted by solar activity.
Answer:
pH=11.
Explanation:
Hello!
In this case, since the data is not given, it is possible to use a similar problem like:
"An analytical chemist is titrating 185.0 mL of a 0.7500 M solution of ethylamine(C2HNH2) with a 0.4800 M solution of HNO3.ThepK,of ethylamine is 3.19. Calculate the pH of the base solution after the chemist has added 114.4 mL of the HNO3 solution to it"
Thus, for the reaction:
Tt is possible to compute the remaining moles of ethylamine via the following subtraction:
Thus, the concentration of ethylamine in solution is:
Now, we can also infer that some salt is formed, and has the following concentration:
Therefore, we can use the Henderson-Hasselbach equation to compute the resulting pOH first:
Finally, the pH turns out to be:
NOTE: keep in mind that if you have different values, you can just change them and follow the very same process here.
Best regards!
