Two point charges (Q_(1))=9.00\times 10^(-9)C,Q_(2)=(-33\times 10^(-9)C) are separated by a distance of r=0.800m. What is the magnitude of the electric field at the midpoint between these charges, in units of ( N)/(C)?

Answer:

Linear Function

Step-by-step explanation:

A linear function has constant slope

That means the ratio of y differences to x differences must be the same throughout the function. In other words the rate of change of the function y value is the same throughout the function

IF we look at the table we see that as x increases by 1, y decreases by 15

For example at x = 0, y = 20 and at x = 1, y = 5

So change in y/change in x = 0  = (5-20)/(1-0) = -15/1 = -15

If we look at another pair of points, say x = 1, y=5 and x = 2, y = -10

we get the rate of change = (-10 - 5)/(2-1) = -15/1 = -15

This is the same for any two x, y pair of values

So it is a linear function

Answer:

The correct statements are:

* The scatter plot has a cluster with a span for variable A from 2 to 7.

* The scatter plot has an outlier at (15, 2).

A scatter plot is a graph that shows the relationship between two variables. The points on the graph are plotted by their coordinates. The independent variable is plotted on the x-axis, and the dependent variable is plotted on the y-axis.

In the scatter plot, the points are clustered around a line. The line represents the relationship between the two variables. The cluster of points means a strong correlation between the two variables. The outlier at (15, 2) indicates that one data point does not fit the general trend.

The scientific definition of work is different in many ways from its everyday meaning. The definition of work in physics reveals its relationship to energy – whenever work is done, energy is transferred.

For a work to be done, in a scientific sense, a force must be exerted, and there must be displacement in the direction of the force. With this said, we can say that Work is the product of the component of the force in the direction of the displacement and the magnitude of this displacement.

Mathematically, the above statement is expressed as follows:

W = (F cos θ) d = F. d

0.26x + 16.9..........

Answer:

y=0.26x+16.9

explanation:

The area of the circle \( r = 4 \sin \theta \) in the first quadrant is 8 square units.

To find the area of the circle \( r = 4 \sin \theta \) in the first quadrant, we need to integrate the equation with respect to theta within the appropriate range.

In the first quadrant, theta ranges from 0 to π/2. We can rewrite the equation as \( r^2 = (4 \sin \theta)^2 \) to eliminate the square root.

Expanding the equation, we get \( r^2 = 16 \sin^2 \theta \).

Using the conversion formula for polar coordinates, the area element in polar coordinates is given by \( dA = \frac{1}{2} r^2 d\theta \).

Substituting the value of \( r^2 \), we have \( dA = 8 \sin^2 \theta d\theta \).

Now, we can integrate the area element from 0 to π/2 to find the total area:

\[ A = \int_0^{\frac{\pi}{2}} 8 \sin^2 \theta \, d\theta \]

Using the trigonometric identity \( \sin^2 \theta = \frac{1 - \cos(2\theta)}{2} \), we can simplify the integral:

\[ A = 8 \int_0^{\frac{\pi}{2}} \frac{1 - \cos(2\theta)}{2} \, d\theta \]

Integrating, we get:

\[ A = 4 \left[ \theta - \frac{\sin(2\theta)}{2} \right]_0^{\frac{\pi}{2}} \]

\[ A = 4 \left( \frac{\pi}{2} - \frac{\sin(\pi)}{2} - 0 + \frac{\sin(0)}{2} \right) \]

\[ A = 4 \left( \frac{\pi}{2} - 0 \right) \]

\[ A = 2\pi \]

Therefore, the area of the circle \( r = 4 \sin \theta \) lying in the first quadrant is 2π square units, which is approximately 6.28 square units when rounded to two decimal places.

Answer:

£15.20

Step-by-step explanation:

butter : sugar : flour = 2 : 1 : 9

Total mass for 1 recipe = 30 g

2 + 1 + 9 = 12

12x = 30

x = 30/12

x = 2.5

For 1 scone:

butter = 2x = 2(2.5) g = 5 g

sugar = x = 2.5 g

flour = 9x = 9(2.5) g = 22.5 g

Cost for 1 scone:

butter: 5 g × £2.50/(500 g) = £0.025

sugar: 2.5 g × £1.60/(1000 g) = £0.004

flour: 22.5 g × £0.6/(1500 g) = £0.009

Cost for 1 recipe = £0.025 + £0.004 + £0.009 = £0.038

Cost for 400 scones = 400 × £0.038 = £15.20

A baking scale measures mass to the tenth of a gram, up to 650 grams. Which of the following measurements is possible using this scale?

a.3.8 grams

b.120.01 grams

c.800.0 grams

d.54 milligrams

Solution

The scale measures mass to the tenth of a gram

The scale measures up to 650 grams

a.3.8 grams

This measures to the tenth of a gram (to one decimal place) and it is not up to 650 grams

b.120.01 grams

This measures to hundredth of a gram ( 2 decimal places) and it is not up 650 grams.

c.800.0 grams

This measures to the tenth of a gram but exceeds the 650 grams limit

The average value of f over the rectangle R is 6(e2 - 1).

To find the average value of the function f(x, y) = 4ey x ey over the rectangle R = [0, 6] ⨯ [0, 1], we need to calculate the double integral of f over R and divide it by the area of R:

fave = (1/area(R)) ∬R f(x, y) dA

where dA denotes the area element in the xy-plane.

First, we can simplify the expression for f(x, y) by using the properties of exponentials:

f(x, y) = 4ey x ey = 4e2y x

Now we can evaluate the integral:

f_ave = (1/area(R)) ∬R f(x, y) dA

= (1/(6*1)) ∫[0,6] ∫[0,1] 4e2y x dy dx

= (1/6) ∫[0,6] 4x ∫[0,1] e2y dy dx

= (1/6) ∫[0,6] 4x [e2y/2]0¹ dx

= (1/6) ∫[0,6] 2x (e2 - 1) dx

= (1/3) (e2 - 1) ∫[0,6] x dx

= (1/3) (e2 - 1) [(6²)/2]

= (18/3) (e2 - 1)

= 6(e2 - 1)

The coordinates of the first point of intersection in rectangular form are (x, y) = ((5/2), (5/2)).

To find the points of intersection between the polar curves r = 5 sin(θ) and r = 5 cos(θ), we need to equate the two equations and solve for θ. Let's start by setting the two equations equal to each other:

5 sin(θ) = 5 cos(θ)

Dividing both sides by 5 gives:

sin(θ) = cos(θ)

Now, we can use the trigonometric identity sin(θ) = cos(90° - θ). Replacing cos(θ) with sin(90° - θ), the equation becomes:

sin(θ) = sin(90° - θ)

Since the sine function is equal to itself for any angle plus multiples of 360°, we can write:

θ = 90° - θ + 360°  x  n

Here, n represents any integer value. Solving for θ, we get:

2θ = 90° + 360°  x  n

Dividing both sides by 2, we have:

θ = 45° + 180°  x  n

Now, let's substitute this value of θ back into the original equation r = 5 sin(θ) (or r = 5 cos(θ)) to find the corresponding r-values.

For θ = 45°:

r = 5 sin(45°) = 5 cos(45°)

Using the values of sine and cosine for 45°, we get:

r = 5  x  √(2)/2 = 5  x  √(2)/2

Simplifying further, we have:

r = (5/2)  x  √(2)

Therefore, the coordinates of the first point of intersection are (r, θ) = ((5/2)  x  √(2), 45°).

Now, let's consider the value of θ for n = 1:

θ = 45° + 180°  x  1 = 45° + 180° = 225°

For θ = 225°:

r = 5 sin(225°) = 5 cos(225°)

Using the values of sine and cosine for 225°, we get:

r = 5  x  (-√(2)/2) = -5  x  √(2)/2

Simplifying further, we have:

r = (-5/2)  x  √(2)

Therefore, the coordinates of the second point of intersection are (r, θ) = ((-5/2)  x  √(2), 225°).

To convert these polar coordinates into rectangular coordinates, we can use the formulas:

x = r  x  cos(θ) y = r  x  sin(θ)

For the first point of intersection, (r, θ) = ((5/2)  x  √(2), 45°):

x = ((5/2)  x  √(2))  x  cos(45°) = (5/2)  x  √(2)  x  √(2)/2 = (5/2) y = ((5/2)  x  √(2))  x  sin(45°) = (5/2)  x  √(2)  x  √(2)/2 = (5/2)
