The magnitude of the repulsive force between a +500μC charge and a +100μC charge which are 5 m apart is 2N.
The repulsive force between two charges = (k q₁ q₂)/r²
q₁ q₂ are the charges
r is distance between the charges
k= 9×10⁹ Nm²C²
F= (500μC) (+100μC)9×10⁹/25
= 2N
A movement between two charges that are same or comparable is referred to as repulsion. The tension between two electrons (negative charge). Two charges of a different sort are drawn toward one another by the force of attraction, which is defined as "a force between two charges that are distinct or different."
At a distance, magnetism is an attractive or repulsive force. The repulsive force gives rise to a metric that measures how a system's gravitational mass changes. According to the force-based approach, the forces that attract and repel other atoms come from their subatomic arrangement and control how they behave.

In mathematics, what is linear equation?There is not more then one or two variables in a linear equation. In a linear equation, no variable is raised to a power larger than one or utilized as the denominator of a fraction. When you locate two values that satisfy a linear equation and display them on a coordinate grid, every one of the points falls on the same line.
What is a linear equation with one variable?A linear equation in one variable seems to be an equation that has just one solution and is stated in the form ax+b = 0, where a but instead b are two integers and x is a variable. 2x+3=8, for example, is a mathematical expression with a single variable.

Given that, the sum of the two numbers is 14.
What is an equation?In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, x represents the smaller of the two numbers.
Then the larger number is
The sum of twice the smaller number and two more than the larger number = 2x+2
Now, x+2x+2=14

Suppose that the world's current oil reserves is
R=1970 billion barrels. If, on average, the total reserves is decreasing by 24 billion barrels of oil each year, answer the following:
A.) Give a linear equation for the total remaining oil reserves, R, in terms of t, the number of years since now. (Be sure to use the correct variable and Preview before you submit.)
R=
B.) 12 years from now, the total oil reserves will be____billions of barrels.
C.) If no other oil is deposited into the reserves, the world's oil reserves will be completely depleted (all used up) approximately_______years from now.
(Round your answer to two decimal places.)
From the given situation, we have that:
A) The linear equation is R(t) = 1970 - 24t.
B) 12 years from now, the total oil reserves will be 1682 billions of barrels.
C) Approximately 82.08 years from now.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, the parameters are given as follows:
b = 1970, m = -24.
Hence the linear function is:
R(t) = 1970 - 24t.
For item b, the amount is of R(12), hence:
R(12) = 1970 - 24(12) = 1682.
12 years from now, the total oil reserves will be 1682 billions of barrels.
For item c, we have to solve for t when R(t) = 0, hence:
1970 - 24t = 0
24t = 1970
t = 1970/24
t = 82.08.
Approximately 82.08 years from now.

Answer:
k = 110
Step-by-step explanation:
You want the integer multiple of pi that is the area of 300° of a donut with inner radius 8 cm and outer radius of 14 cm.
Area of a circleThe area of a circle is given by the formula ...
A = πr²
Then the area of the outer circle is ...
A = π(14 cm)² = 196π cm²
The area of the inner circle is ...
A = π(8 cm)² = 64π cm²
Donut areaThe area of the whole donut is the difference of these areas:
whole donut area = (196 -64)π cm² = 132π cm²
Shaded areaThe shaded area of the figure represents 300° of the 360° full donut. The area is proportional to the central angle, so the shaded area is ...
shaded area = (300°/360°)×whole donut area
shaded area = 5/6 × 132π cm² = 110π cm²
Comparing this to the expression kπ cm², we see that ...
k = 110

If the demand function for a commodity is given by the equation p2 + 16q = 1200 and the supply function is given by the equation 300 − p2 + 10q = 0, find the equilibrium quantity and equilibrium price. (Round your answers to two decimal places.)
The equilibrium quantity and equilibrium price are 34.62 and 25.42 respectively
How to find the equilibrium quantity and equilibrium price?The functions are given as
Demand: p^2 + 16q= 1200
Supply function: 300 - p^2 + 10q
Rewrite the demand function as
p^2 + 16q - 1200 = 0
At equilibrium, demand = supply
So, we have:
p^2 + 16q - 1200 = 300 - p^2 + 10q
Using a graphing calculator, we have:
