What is the principle of conservation of energy?

The word "conservation" in physics describes anything that doesn't change. This indicates that a conserved quantity is represented by a variable in an equation that is constant over time. Its value is the same whether an event occurs before or after it.

In physics, there are a lot of conserved quantities. For making forecasts in what would otherwise be exceedingly complex situations, they are frequently remarkably useful. There are three fundamental quantities in mechanics that are conserved. They are power, forward motion, and angular momentum.

According to question

Mass of the ball = 0.2 kg

Maximum height of the ball = 4 m

Gravity = 9.8 m/s²

Therefore:

Using conservation of energy, we know that P.E. top = K.E. bottom. This tells us that the potential energy at the top is all converted to kinetic energy at the bottom. We can substitute the equations for potential energy and kinetic energy

Initial kinetic energy + Initial potential energy =  Final kinetic energy + Final potential energy

1/2mv² + 0 = mgh + 0

½(0.2)v² = (0.2)(9.8)4

v² = 78.4

Answer:

[tex]x = 180 - \frac{y}{2}[/tex]

Step-by-step explanation:

Our goal here is to isolate [tex]x[/tex] on one side of the equals sign

[tex]360 = 2x + y[/tex]

Here we have 2 terms on the right side of the equals sign, [tex]2x[/tex] and [tex]y[/tex]

in order isolate the [tex]x[/tex] term we must subtract [tex]y[/tex]

However, if we subtract [tex]y[/tex] from one side of the equation we must also do the same to the other side to a maintain balanced equation.

[tex]360 = 2x + y[/tex]
[tex]-y[/tex]           [tex]-y[/tex]

[tex]360 - y = 2x[/tex]

Now to remove "2" from [tex]2x[/tex] we must do the opposite of multiplication, which is division.

There are 270725 different ways to select 4 from 52 cards if I don't care about the order of cards in my hand.

Permutation and combination: The process of ordering objects or numbers is known as permutation. Combinations are a method of choosing items or numbers from a collection or group of items so that the order of the items is irrelevant.

Combinations are used to group objects or to determine how many subgroups can be formed from the given collection of objects. Additionally, we use permutations to determine the number of potential combinations of unrelated objects.

For example, if we want to select 2 players from 6. This will be:

= 6! / 2! (6 - 2)!

= 15 ways

In the given question use the combination. We can write as:

[tex]52C_{4}[/tex] = 52!/4! (52-4)!

This expression could be written in the form

[tex]52C_{4}[/tex] = 52!/4! (52-4)!

[tex]52C_{4}[/tex] = 52!/(4! (48)!)

[tex]52C_{4}[/tex] = 52 x 51 x 50 x 49 x 48!/(4 x 3 x 2 x 48!)

As, 48! cancel out. We get,

[tex]52C_{4}[/tex] = 52 x 51 x 50 x 49/24

       = 6497400/24 = 270725

Hence, there are 270725 ways.

The best approximation for the area of the circle is 201.0in³

The size of a region on a planar or curved surface is expressed mathematically as area. The term "surface area" refers to the area of an open surface or the perimeter of a three-dimensional object, whereas "plane area" refers to the area of a shape or planar lamina. Area can be thought of as the amount of a certain thickness of material required to construct a model of the shape. For the areas of basic forms like circles, triangles, and rectangles, there are a number of well-known formulas. Any polygon can be divided into triangles to get its area using these formulas. Calculus is commonly needed to calculate the area of forms having curved boundaries. Calculus' historical growth was in large part driven by the issue of figuring out the area of plane figures.

It is possible to calculate a shape's area.

As we already know that,

The area of a circle=πr²

Here, r=8in

π=3.14

Then,

A=(3.14)(8²)

A=201.0in²

Therefore, Area=201.0in²

The absolute value function which will be narrower than  the parent function is:

f(x) = 2.9|x|

Given parent function is f(x)=|x|

Now we have to find which function from given choices will be narrower than the parent function.

Notice that adding or subtracting some number from the parenth function only shifts the graph up, down, left of right side.

But that will not make function narrorwer or broader.

So f(x) = |x – 2| and  f(x) = |x| + 3, can't be the answer.

Multiplying by some positive real number which is more than 1, makes function narrower.

Only f(x) = 2.9|x| from remaining choices fits that case.

Hence f(x) = 2.9|x| is the final answer.

f(x) = 1.2|x + 8|  will also make the function narrower but will shift the parent function too.

The surface area of the plane is π√14 sq. units.

It is given in the question that the equation of the plane = x+2y+3z=1 and that of the cylinder

= x² + y² = 5                                                                  [1]      

Let J be the projection on the plane x+2y+3z=1

We know that the surface area of an equation is

∫∫j  √{1+(∂z/∂x)² + (∂z/∂y)²} dA

We know that the plane is inside the cylinder.

By using the coordinates of the cylinder we can get

x = r cosθ and y = rsinθ

Squaring both sides gives us

x² = r²cos²θ

y² = r²sin²θ

Therefore we get,

x² + y² =  r²cos²θ + r²sin²θ

= r²(cos²θ + sin²θ)

We know that cos²θ + sin²θ = 1. Hence,

=  r²                                                                         [2]

From equations [1] and equation [2] we get

r² =  5

or, r = √5

Hence,

J = {(r,θ)/ 0 ≤ r ≤ √5, 0 ≤ θ ≤ 2π}

Therefore,

x +2y + 3z =1

or, z = 1/3(1 - x - 2y)

Partially differentiating z with respect to x and with respect to y gives us

∂z/∂x = -1/3

and,

∂z/∂y = -2/3

Therefore,

We already know that Surface Area = ∫∫j √{1+(∂z/∂x)² + (∂z/∂y)²} dA

= ∫∫j √{1+ (-⅓) ² + (-⅔) ²} dA

= ∫∫j √(9+1+4)/√9 dA

= √14 /3∫∫j dA

=√14/2 [2π - 0]

Answer:

28 divided by 66.29 is approximately 0.4223. To find the exact result, you would need to perform long division. The process for doing this is as follows:

Begin by dividing the leftmost digit of the dividend (28 in this case) by the divisor (66.29). In this case, the result is 0 with a remainder of 28.

Bring down the next digit of the dividend (0 in this case), so that the dividend is now 280.

Divide 280 by 66.29. The result is 4 with a remainder of 36.29.

Bring down the next digit of the dividend (0 in this case), so that the dividend is now 36.29.

Divide 36.29 by 66.29. The result is 0.54 with a remainder of 0.29.

Bring down the next digit of the dividend (0 in this case), so that the dividend is now 0.29.

Divide 0.29 by 66.29. The result is 0.004 with a remainder of 0.

The remainder is 0, so the division is complete. The result is 0.004223.

557,568 inch³ of refrigerant can be held by the tubing.

Here we have to find how much a refrigerant can hold.

Data given:

outer diameter (d) = 78inch

outer radius(r) = 39 inch

inner diameter (d') = 34 inch

inner radius (r') = 17inch

Height (h) = 12 feet

= 12 × 12

= 144 inch

the formula to find the volume of the cylinder:

volume= пr²h

So here we get

Refrigerant hold = Volume of the outer cylinder - the volume of the inner cylinder

= πr²h - πr'²h

= πh(r² - r'²)

= π ×144 ( 39² - 17²)

= π × 144 ×56 × 22

= 22/7 × 144 × 56 × 22

The slope of the line that passes through (4,1) and (2,5) is -2.The slope of a line can be expressed in many ways, including as a fraction, decimal, or even in terms of the angle of inclination.

The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.The slope of a line is calculated by finding the difference in the y-values (rise) divided by the difference in the x-values (run).

In this case, the rise is 5 - 1 = 4 and the run is 2 - 4 = -2.

Therefore, the slope of the line is 4/-2 = -2.

In the case of a horizontal line, the slope is 0, and in the case of a vertical line, the slope is undefined. The slope is a useful tool in mathematics as it can be used to determine the equation of a line, the rate of change on a graph, or the amount of change for every unit of time.
