The force between a positively charged plastic and a neutral paper is :
Attractive because the plastic polarizes the paper Force of attractionThe force of attraction between a positively charged material and a neutral material becomes stronger as the positively charged material polarizes the neutral material which enables it to exert an attractive force on the neutral material. while
The electrical force of attraction between charged materials reduces with the increase in distance between them.
Hence we can conclude that the force between a positively charged plastic and a neutral paper is attractive because the plastic polarizes the paper.

An 800 kg cart is coasting at a constant velocity of 15 m/s. As the car coasts, a 200 kg block is dropped into it. What would be the velocity of the cart now?.
Using conservation of momentum, we will see that the new velocity is 12 m/s.
How to use conservation of momentum?
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.

[tex] {h}^{ + } [/tex]
An acid is a polar substance that dissolves in water and produces hydrogen ions.
What are acids?
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.

Your take home pay is $1500 after you have 22% withheld in taxes. What is your gross pay before the taxes were withheld? round your answer to the nearest penny.
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
Calculation of TaxGiven 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
x = $1923.076

For real numbers $x,$ what is the largest possible value of \[ 5 - (x-3)^2 ?\].
The largest possible value of f(x) will be -∞.
LimitFor 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]-∞.
