<h2>Emerging Technologies that will make Hydroelectric Energy Source Safer</h2>

The variation in technology to labor lower loads and higher peaks make the hydroelectric energy source safer, more usable, more efficient and cleaner. The plants can also adapt speed drives changing the capability to suffice various sorts of demands which includes great speed response. Such variation can alter the income rate by 85%. The spread of operating range of the plant can increase income rate by 61%.

For question #17, use the following picture:
Serhud [2]

Explanation:

18. __Double displacement__ 2LiBr + Pb(NO₃)₂ → PbBr₂ + 2LiNO₃

In a double displacement reaction, there is an actual exchange of partners to form new compounds.

 The driving condition for this kind of reaction are:

  • formation of an insoluble compound called precipitate
  • formation of water or any other non-ionizing compound
  • liberation of a gaseous product.

19. ___Single displacement___ Fe + 2HCl  → FeCl₂  + H₂

In a single displacement reaction, one substance replaces another.

  • The replacement of a metallic ion in solution by a metal higher in the activity series than the metal in solution falls into this category.
  • The positions of the two elements in the activity series serves as the driving force.

20. ___Synthesis___ CaO + H₂O  →  Ca(OH)₂

Synthesis is a combination reaction

  • This reaction involves the formation of a single product from two or more reactants.
  • A compound forms from the union of two or more reactants
  • The large and negative heat of formation of the product is the driving force for this reaction.

21. ______Decomposition__ NiCl₂   →  Ni + Cl₂

In a decomposition or cracking reaction, two or more product forms from a single reactant.

The breakdown of a compound into its component individual elements or other compounds fall into this category.

  • The driving force for this reaction is the high heat of formation of the compound and the extreme instability of the compound.
  • A stable compound can also be decomposed on heating and applying pressure.

An object increases vert its velocity from 22M/S 236M/S and five seconds. What is the acceleration of the object
MariettaO [177]

Answer:

\boxed {\boxed {\sf a=42.8 \ m/s^2}}

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

a=\frac{v-u}{t} (<em>v </em>is the final velocity, <em>u</em> is the initial velocity, <em>t </em>is the time).

The velocity increased from 22 m/s to 236 m/s in 5 seconds. Therefore:

v=236 \ m/s\\u=22 \ m/s\\t= 5 \ s

Substitute the values into the formula.

a=\frac{236 \ m/s - 22 \ m/s}{5 \ s}

Subtract in the numerator.

  • 236 m/s-22 m/s=214 m/s

a=\frac{214 \ m/s}{5 \ s}

Divide.

a=42.8 \ m/s^2

The acceleration of the object is <u>42.8 meters per square second.</u>

Correct the sentence below to reflect an “I” statement. 
Anarel [89]
The word “you” shouldn’t be used, and I learned the I statement to have your feelings stated, then when, then because, and finally a want. So, to correct this, an appropriate statement would be “ I feel misunderstood when I am treated like a child because my curfew is set for 9:00 pm on the weekends and I want to be seen as your equal and as though you are not superior to me. You can use the word “you” after stating you want something out of the other person.

A neutral metal comb is held near an object with a negative charge. What happens to the comb?
mixas84 [53]

Answer:

Neutral comb is charged through induction.

Explanation:

The local charging of the comb is caused because of induction. The electron is pushed in the comb to the away side of the charged particle because of the negative charge which makes the close part positively charge.

Then after that when the observer move the comb away from the charge then the electron of the comb is redistributed.
