An acid is a polar substance that dissolves in water and gives hydrogen ions

[tex] {h}^{ + } [/tex]

An acid is a polar substance that dissolves in water and produces hydrogen ions.

An acid is a chemical that, when added to water, releases hydrogen (H+) ions. A hydrogen ion is made up solely of a proton. When examining the chemical formulas of various acids, we can see that they all include at least one hydrogen (H).

Any acid that entirely ionizes in solutions is considered a strong acid. This indicates that when dissolved in a solution, it emits the most hydrogen ions or protons.

For instance: Hydrochloric acid or HCl Acids are examples of organic chemicals that belong to the carboxylic acid, sulfonic acid, and phenol groups as well as the inorganic substances known as the mineral acids, such as sulfuric, nitric, hydrochloric, and phosphoric acids.

Therefore, a polar chemical that dissolves in water to form hydrogen ions is an acid.

The emf of the solar cell moving the electrons from the positive to the negative terminal is 1.5 V

The electromotive force (EMF) is defined as the energy supplied by a battery per unit charge. Mathematically, it can be expressed as:

Electromotive force (EMF) = Work (W) / charge (Q)

EMF = W / Q

EMF = W / Q

EMF = 2.4×10¯¹⁹ / 1.6×10¯¹⁹

EMF = 1.5 V

Light from the sun allows a solar cell to move electrons from the positive to the negative terminal, doing 2.4×10−19 J of work per electron. What is the emf of this solar cell?

Answer:

461 = dividend

3 = divisor

Explanation:

Step 1:

Start by setting it up with the divisor 3 on the left side and the dividend 461 on the right side like this:

   3 ⟌ 4 6 1

Step 2:

The divisor (3) goes into the first digit of the dividend (4), 1 time(s). Therefore, put 1 on top:

       1    

   3 ⟌ 4 6 1

Step 3:

Multiply the divisor by the result in the previous step (3 x 1 = 3) and write that answer below the dividend.

       1    

   3 ⟌ 4 6 1

      3    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (4 - 3 = 1) and write the answer below.

       1    

   3 ⟌ 4 6 1

     - 3    

       1    

Step 5:

Move down the 2nd digit of the dividend (6) like this:

       1    

   3 ⟌ 4 6 1

     - 3    

       1 6  

Step 6:

The divisor (3) goes into the bottom number (16), 5 time(s). Therefore, put 5 on top:

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

Step 7:

Multiply the divisor by the result in the previous step (3 x 5 = 15) and write that answer at the bottom:

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

       1 5  

Step 8:

Subtract the result in the previous step from the number written above it. (16 - 15 = 1) and write the answer at the bottom.

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1  

Step 9:

Move down the last digit of the dividend (1) like this:

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

Step 10:

The divisor (3) goes into the bottom number (11), 3 time(s). Therefore put 3 on top:

       1 5 3

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

Step 11:

Multiply the divisor by the result in the previous step (3 x 3 = 9) and write the answer at the bottom:

       1 5 3

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

           9

Step 12:

Subtract the result in the previous step from the number written above it. (11 - 9 = 2) and write the answer at the bottom.

       1 5 3

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

     -     9

           2

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Answer:

Explanation:

The largest possible value of f(x) will be -∞.

For solving this question, you can calculate the limit of f(x) for x→∞.  Since the definition of limit is: the limit of  f(x), as x approaches b , equals L. See:  [tex]\lim _{x\to \ b \:}f(x))=L[/tex]

Therefore:

[tex]\lim _{x\to \infty \:}\left(5-\left(x-3\right)^2\right)\\ \\ \lim _{x\to \infty \:}\left(5\right)-\lim _{x\to \infty \:}\left(\left(x-3\right)^2\right)[/tex]

Applying the Constant Law -   The limit of a constant is the constant itself: [tex]\lim _{x\to \infty \:}\left(5\right)=5[/tex]

Applying the Difference Law -  The limit of a difference is the difference of the limits: [tex]\lim _{x\to \infty \:}\left(\left(x-3\right)^2\right)=\infty[/tex]

Thus,

[tex]\lim _{x\to \infty \:}\left(5-\left(x-3\right)^2\right)= \lim _{x\to \infty \:}\left(5\right)-\lim _{x\to \infty \:}\left(\left(x-3\right)^2\right)= 5- \infty=- \infty[/tex]

The largest possible value of f(x) will be -∞.

The result is consistent since it is possible to note that [tex](x-3)^2[/tex]positive number. Also, see that there is a difference between 5 and  [tex](x-3)^2[/tex]-∞.

Using the values given for the take home and tax as 227% , we assumed a gross pay of x value and found the gross pay to be $1923.076

Given Data

Take home pay = $1500

Tax = 22% of gross

Let the gross pay be x

Hence, let us find 22% of x

= 22/100*x

=0.22x

Amount of pay = 0.22x

We know that the Take home pay is  = Gross - Tax

Substituting our data we have

1500 = x-0.22x

1500 = 0.78x

Divide both sides by 0.78

x = 1500/0.78

Using conservation of momentum, we will see that the new velocity is 12 m/s.

We know that the momentum un a closed system must be conserved, in this case, our system is the cart and the block.

Initially, the cart moves with a velocity of 15 m/s, and has a mass of 800 kg, then the initial momentum is:

P = 15m/s*800kg = 12,000 kg*m/s

Then a block of 200kg is dropped on the cart, so the new mass of the cart is 1,000 kg, then the new momentum is:

P = 1,000kg*V'

Where V' is the new velocity, and by conservation of momentum, we must have that:

12,000 kg*m/s = 1,000kg*V'

( 12,000 kg*m/s)/1,000kg = V' = 12 m/s.

The new velocity of the cart is 12 m/s.
