A particle (charge = +40 uc) is located on the x axis at the point x = -20 cm, and a second particle (charge = -50 uc) is placed on the x axis at x = +30 cm. What is the magnitude of the total electrostatic force on a third particle (charge = -4. 0 uc) placed at the origin (x = 0)?.

Answers

Answer 1

The total electrostatic force on the third particle will be 56 N in -x direction.

q1 = +40 μC, x1 = -20 cm = - 0.2 m

q2 = -50 μC, x2 = 30 cm = 0.3 m

q = -4 μC, x = 0

We know that, the electrostatic force between two charges

F = kQ1Q2/d²

k = 9 × 10⁹ Nm²/C²

here, d: distance between two charges

F1 = k(40×10⁻⁶)(-4× 10⁻⁶)/(0.2)²

F1 = - 36 N {(-) sign shows the force is attraction force}

so, the direction of F1 on q is -x-direction

F2 = k(-50×10⁻⁶)(-4× 10⁻⁶)/(0.3)²

F2 = 20 N {Repulsive force because both particles are having negative charge}

so, the direction of F2 on q is in the -x-direction

So Total force F = F1+F2 = 20+36 = 56 N

Therefore, the total electrostatic force on the third particle will be 56 N in the -x direction.

How to construct and plot the data in a scatter plot?

In this scenario, the street distance (in centimeters) would be plotted on the x-axis (x-coordinate) of the scatter plot while the weight (in Newtons) would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

From the scatter plot (see attachment) which models the relationship between the street distance (in centimeters) and weight (in Newtons), a linear equation for the line of best fit is given by:

y = 1.30x - 2.30

In conclusion, we can reasonably infer and logically deduce that the scatter plot indicates a linear relationship between the street distance (in centimeters) and weight (in Newtons).

Make a table of values, graph the function and use the graph to estimate the sales 12 weeks after release.

Answers

In 33 weeks, they will have sold 150 units.

What is sales of products?

Selling a good or service in exchange for cash, a benefit, or some other kind of payment is known as product sales. When a customer purchases a good or service that will meet their needs, the transaction is known as a product sale. The quantity of goods sold during a specific time period aids in calculating product sales.

Step by Step Explaination:

Equation that models the sales of the product

The equation that models the sales of the product after an initial release exists:

s = 12√4 + 10

where s denotes the total sales (in thousands)

t denotes the time in weeks

you want to replace the s with 150 in the equation and then just solve

for t.

150 = 12√4t + 10

Subtract 10 from both sides

150 - 10 = 12√4t + 10

140 = 12√4t

Divide both sides by 12      

11.66= √4t  

Taking square root on both sides of the equation.    

135.95 = 4t      

Now divide both sides by 4

33.98 = t (approximately).

so in 33 weeks, they will have sold 150 units.

Binomial expansion

The coefficient of the expansion are found in Pascal's triangle (attached). Row 5 is used for the 5th power:

  (a +b)^5 = a^5 +5·a^4·b + 10·a^3·b^2 +10·a^2·b^3 +5·a·b^4 +b^5

Answers

Other than itself, ∠FGE is an angle that is congruent to ∠FGB.

What is congruent angle?

Angles that are congruent with one another include two or more angles. This means that the dimensions of these angles are same. Angles can be acute, obtuse, exterior, or interior, and the congruence of angles is unaffected by their type. Congruent angles aren't always supplementary angles, in general. Angles must be complementary in order for the sum to be 180. Since right angles and supplementary angles have the same measure and sum up to 180, they are the only angles that can be said to be congruent.

Because ∠FGE and ∠FGB are supplementary angles, so they add up to 180 degrees. Because angle ∠FGE is 90 degrees, or a right angle, that means ∠FGB must also be 90 degrees. This makes them congruent.

Answers

Answer: The value of f(-1) is equal to 5(-1)^2 + (-1) + 4 = -5 + (-1) + 4 = -2

Step-by-step explanation:

To evaluate f(-1), we substitute -1 for x in the function f(x)=5x^2+x+4. This gives us f(-1)=5(-1)^2+(-1)+4. We simplify this by applying the exponent first, so (-1)^2=1. Then we substitute the result in the function, which gives us f(-1)=5(1)+(-1)+4. Now we can simplify it by adding and subtracting the values which gives us f(-1)=5+(-1)+4=8.

What does it mean to get a 150% salary raise? Explain in words and then give an example showing a

Answers

Answer:

If someone get a 150% salary raise, it means that the current salary will be increased by 1.5 (150/100) from the current amount.

To demonstrate this, let's assume that someone's salary is $1000, if we increase it by 150% we must calculate 150% of $1000.

[tex]1000*150\%=1000*\frac{150}{100} =1500[/tex]

150% of $1000 is $1500, since the person wll get a 150% salary raise, it means that the actual salary INCREASES that value, the final salary of a person will be:

Final salary = previous salary + amount of increase

Final salary = $1000 + $1500

Final salary = $2500
