Why physics is hard?

Physics requires the ability to solve problems, which can only be acquired via practice. In addition to these difficult ideas, there are theoretical concepts, mathematical calculations, and laboratory experiments.

How to deal with physics?

It is better to comprehend the derivations than to memorise the formulas. Making a mess of several formulas will just increase your anxiety over the topic. Instead, if you strive to comprehend where they originate, you will begin to appreciate physics and its applications.

Physics is a difficult topic since it combines science and arithmetic, which may be challenging for the best of us. Nevertheless, despite how difficult it is, you can achieve if you follow a few simple guidelines and put yourself through some practice.

What is a median of 25?

Answers

The median of the first 25 whole numbers is 12.

The median is the middle point in a dataset—half of the data points are smaller than the median and half of the data points are larger.

The data set's median is the value in the center. Put all the numbers in ascending or descending order, and then choose the middle number to determine the median. There will only be one middle integer if the number of data points is odd. If the number of data points is even, you must choose the middle two numbers, add them together, and divide by two.

The first 25 whole numbers are as follows:-

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24

Here total no. of terms = n = 25 which is odd.

Therefore median = (n + 1)/2 th term

= (25 + 1)/2 th term

= 26/2 th term

= 13th term

Here, the 13th term is 12

Hence, the median of the first 25 whole numbers is 12.

Gabriella has 60 m of fencing to build a four-sided fence around a rectangular plot of land. The area of the land is 209 square meters. Solve for the dimensions (length and width) of the field.

Answers

The length and width of the rectangular plot of land is (209 / (60 - l)) and (60 - (209 / (60 - l))), respectively.

The formula to calculate the dimensions of a rectangular plot of land is area = length x width, or A = l x w. In this problem, the area of the land is 209 square meters, so A = 209. We know that Gabriella has 60 meters of fencing to build a four-sided fence around the land, so the length and width of the field must add up to 60 meters. This can be written as l + w = 60. To solve for the length and width of the field, we can first substitute the value for the area of the land into the equation for area: A = l x w. This equation can be rewritten as l x w = 209. We now have two equations that can help us solve for the length and width of the field.

We can solve this system of equations using substitution. We can substitute the equation l + w = 60 into the equation l x w = 209. This simplifies the equation to l x (60 - l) = 209. We can then solve for l by dividing both sides of the equation by (60 - l). This results in l = (209 / (60 - l)). We can then substitute this into the equation l + w = 60 to solve for w. This simplifies to w = (60 - (209 / (60 - l))).

Therefore, the length and width of the rectangular plot of land is (209 / (60 - l)) and (60 - (209 / (60 - l))), respectively.

Answers

The integral || curl F || dĞ is equal to -2. The correct answer is therefore option D that is -87.

To evaluate the integral || curl F || dĞ using Stoke's Theorem, we need to find a vector field F and a surface S such that the boundary of S is a closed curve C and the integral is equal to the flux of the curl of F through S. Using the given information, we can find the components of F as:

F = (-y, x, r)

The curl of F is given by:

curl F = (0, 0, 1)

The surface S is the part of the sphere r2 + y2 + z2 = 4 that lies above the cy-planes, oriented upward. This surface can be parameterized by:

x = rcosφcosθ

y = rcosφsinθ

z = rsinφ

where 0 ≤ φ ≤ π and 0 ≤ θ ≤ 2π.

The boundary of S is the curve C, which is the intersection of the sphere and the cy-plane. This curve can be parameterized by:

x = rcosθ

y = rsinθ

z = 0

where 0 ≤ θ ≤ 2π.

Using Stoke's Theorem, the integral || curl F || dĞ is equal to the flux of curl F through S, which is given by:

∫|| curl F || dĞ = ∫curl F · ndC

where n is the unit normal vector to the surface S.

Substituting the expressions for curl F and the parameterizations of S and C, we get:

∫|| curl F || dĞ = ∫(0, 0, 1) · (cosφcosθ, cosφsinθ, sinφ)dC

= ∫(sinφ)dC

You want to know how the form of a linear equation can be used to reveal its key characteristics.

Key Characteristics

The characteristics of a linear equation that are of interest for this problem are ...

Forms of a linear equation

A linear equation can be written in many forms. Some of these forms make it easy to determine one or more of the key characteristic listed above. Some of the more common forms are Slope-Intercept form, Point-Slope form, and Standard form. There are a number of others.

Slope-Intercept form

The slope-intercept form is ...

  y = mx + b

where m is the slope, and b is the y-intercept. This form makes it easy to determine ...

slopey-intercept

This equation cannot be used to describe a vertical line.

Alternate Slope-Intercept form

We can rearrange the above equation to reveal the x-intercept.

  y = m(x -a)

where m is the slope and 'a' is the x-intercept. This form makes it easy to determine ...

slopex-intercept

This equation cannot be used to describe a horizontal line (except y=0).

Point-Slope form

The equation of a line with slope m through point (h, k) can be written as ...

  y -k = m(x -h)

This makes it easy to determine ...

slopea point on the line (not necessarily an intercept)

This equation cannot be used to describe a vertical line.

Standard form

The standard form equation of a line is similar in style to the standard form equations for other geometric figures (circle, ellipse, hyperbola). This form is ...

  Ax +By = C

where A, B, C are mutually prime (integers), and A ≥ 0. If A = 0, then B > 0. That is, the leading coefficient is positive. Integers are preferred for the coefficients, but some lines have irrational slope or other key characteristics, so integers may not be able to be used in all places.

The key characteristics cannot be read from the equation directly, but they are one step away:

slope = -A/Bx-intercept = C/Ay-intercept = C/B

Solving for the intercepts is especially easy, so we list this form as one that can be efficient for determining the intercepts.

Intercept form

A very nice form for efficiently determining the intercepts, or efficiently writing an equation from the intercepts is ...

  x/a +y/b = 1

where 'a' is the x-intercept, and 'b' is the y-intercept. This form makes it very easy to determine ...

x-intercepty-intercept

You may notice that dividing the standard form equation by C and rearranging the coefficients will give you this form:

  Ax +By = C

  (A/C)x +(B/C)y = 1 . . . . . . . divide by C

  x/(C/A) +y/(C/B) = 1 . . . . . . . intercept form

General form

The general form of a polynomial equation of any degree is ...

  f(x, y) = 0

The general form of a linear equation is ...

  Ax +By +C = 0

This is simply a rearrangement of the Standard form equation. Equations written in this form can be helpful for ...

Various 2-Point forms

When two points are given, and you want an equation of the line, various forms are available for using those coordinates. These forms make use of the fact that the slope of a line is the same everywhere, so the ratio of any difference of y-coordinates to the corresponding difference of x-coordinates is a constant (the slope). Again, slopes of 0 or "undefined" can cause trouble with certain of these forms. Here are several different arrangements of 2-point forms:

  [tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\(x_2-x_1)(y-y_1)=(y_2-y_1)(x-x_1)\\\\\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}=m\qquad\text{Slope form}\\\\\\\dfrac{x-x_1}{y-y_1}=\dfrac{x_2-x_1}{y_2-y_1}\qquad\text{inverted from the above}\\\\\\\dfrac{y-y_1}{y_2-y_1}=\dfrac{x-x_1}{x_2-x_1}[/tex]

The last three "ratio forms" are variations of each other. Any such proportion can be written 4 ways. (3 are shown) The form not shown has the variables in the denominator, which is usually not useful.

All of these forms can be written in a "general form" by subtracting one side.

The slope can be read directly from the 1st and 3rd of the forms shown here. It is m = (y2-y1)/(x2-x1).

The slope form is useful for determining ...

slope

Determinant form

Another 2-point form is one written as a determinant:

  [tex]\left|\begin{array}{cc}x-x_1&x_2-x_1\\y-y_1&y_2-y_1\end{array}\right|=0[/tex]

__

Additional comment

It can be useful to recognize the various forms and their relationship to known points on the line or other key characteristics of the function. Any of the slope or point-slope forms make it easy to write the equations of parallel or perpendicular lines through a given point. (The standard and general forms can be used for this, too.)

How do you calculate slope step by step?

When a straight line's equation is not available, determining its slope involves three stages. Determine the first two points on the line. Choose one to be (x1, y1) and the other to be in step two (x2, y2). Step three is to compute slope using the slope equation.

If you have the coordinates of two points on a line, you can use the slope formula to determine that line's slope. The slope equation is given by [tex]m=(y_{2}- y_{1} )/(x_{2} -x_{1} )[/tex], which is the ratio of the change in the y values to the change in the x values. x1 and y1 are the coordinates of the first point.

The inverse of a number is it's reciprocal. Divide 1 by the number to obtain its reciprocal.

For example, the reciprocal of 5 is 1/5, and the reciprocal of 0.5 is 2. The reciprocal of a number x is denoted by 1/x or x^(-1).

For example, to find the reciprocal of 8, you would divide 1 by 8, like this:

1/8 = 0.125

To find the reciprocal of a fraction, you can also turn the fraction upside down to get its reciprocal. For instance, 4/3 is 3/4's inverse.

To find the inverse of a matrix, you can use the following formula:

A^(-1) = (1/det(A)) * adj(A)

where A is the matrix, det(A) is the determinant of the matrix, and adj(A) is the adjugate of the matrix. The transposition of a matrix's cofactor matrix is adjugate. The cofactor matrix is a matrix of the determinants of the minors of the original matrix, each of which is multiplied by a cofactor (-1)^(i+j). The minors of a matrix are the determinants of the square submatrices formed by deleting one row and one column from the matrix. The determinant of a matrix is a scalar value that can be computed from its elements.

For example, consider the matrix A:

[a b]

[c d]

The determinant of A is:

det(A) equals (a * d) - (b * c).

The cofactor matrix of A is:

[d -b]

[-c a]

The adjugate of A is the transpose of the cofactor matrix, so it is:

[d -c]

[-b a]

The inverse of A is then:

A^(-1) = (1/det(A)) * adj(A)

= (1/((a * d) - (b * c))) * [d -c]

How do one find the slope of a graph?

The slope is computed mathematically as "rise over run" (change in y divided by change in x).

In accordance with the slope equation, the slope of such a line may be determined by dividing the rise of the line between two positions by the run of the same line between the same two sites.

b = y - intercept

A line that is perpendicular to it is y = (-1/m) x + b

The slope of the perpendicular line is -1/m

Rewriting the given equation 2y = 3x - 1, we get:

y = (3/2) x - 1/2

So, the slope of the perpendicular line is the reciprocal of 3/2 which is multiplied by -1.

The slope of the line = -2/3

Therefore, the slope of a line that is perpendicular to the line whose equation is 2y = 3x - 1 is -2/3.

Answers

The required regression  equation for the line of best fit, where x represents the month and y-hat represents the predicted time is;

y = -2.78x + 48.5

How to find the regression equation?

A regression equation is defined as the equation that is used in stats to find out what relationship, if any, exists between sets of data

From the given table, let x represents the month and y represents the time. Thus;

Mean of x; x-bar = (1+2+3+4+5+6)/6 = 21/6

x-bar = 3.5

Mean of y; y-bar = (47+43+39+36+35+33)/6

y-bar = 233/6 = 38.83

∑x = 21

∑y = 233

Using statistics calculator;

Sum of squares (SSX) = 17.5

Sum of products (SP) = -48.5

The general form of a regression Equation is;

y-bar = bx-bar + a

Where;

b = SP/SSX

= -48.5/17.5

= -2.77143

a = y-bar - b(x-bar) = 38.83 - (-2.77×3.5) = 48.53333

y = -2.78x + 48.5

Thus, the required regression equation is y = -2.78x + 48.5 for the line of best fit.

What is a transformation in math grade 7?

Answers

A transformation in mathematics is a process of manipulating a polygon.

A transformation in maths is nothing but a process that manipulates a polygon or any other two-dimensional object on a plane or coordinate system. A transformations describe how two-dimensional figures move around a coordinate system.

The original shape of the object before any transformation is called the Pre-Image and the final shape and position of the object is called as the Image.

In mathematics, there are five different transformations:

Dilation, Reflection, Rotation, Shear and Translation

Therefore, transformation is a process of manipulating a polygon.

What is the formula of mean method?

Answers

The formula of mean method is  [tex]\frac{Sum of all values}{Number of values}[/tex].

The formula for the mean, also known as the average, is:

mean =  [tex]\frac{sum of all values}{number of values}[/tex]

For example, if you have a list of numbers [1, 2, 3, 4], the mean would be calculated as follows:

mean = (1 + 2 + 3 + 4) / 4 = 10 / 4 = 2.5

The mean is a measure of central tendency that gives you an idea of the typical value in a set of numbers. It is calculated by adding up all the values in the set and dividing the sum by the number of values.
