The momentum of a proton would be:

(a) For particle moving with speed 0.010c

p = 5.016 × 10^(-21) kgms^{-1}

p = 9.398 MeV/c

(b) For particle moving with speed 0.50c

p = 2.89 × 10^(-19) kgms^{-1}

p = 541.5 MeV/c

(c) For particle moving with speed 0.90c

p = 23.73 × 10^(-19) kgms^{-1}

p = 4446.35 MeV/c

For given question,

We need to calculate the momentum of a proton moving with a given speed.

We know that, the equation for relativistic momentum is,

\(p=\frac{mv}{\sqrt{1-\frac{v^2}{c^2} } }\)

We know, the mass of proton (m) = \(1.67\times 10^{-27}\) kg

(a) For particle moving with speed 0.010c

v = 0.010c

the momentum of a proton would be,

\(\Rightarrow p=\frac{(1.67\times 10^{-27}kg)\times (0.010\times 3\times 10^8)\frac{m}{s} }{\sqrt{1-\frac{0.01^2~c^2}{1^2~c^2} } }\\\\\Rightarrow p=5.016\times 10^{-21}~~kgms^{-1}\)

(b) For particle moving with speed 0.50c

v = 0.50c

the momentum of a proton would be,

\(\Rightarrow p=\frac{(1.67\times 10^{-27}kg)\times (0.50\times 3\times 10^8)\frac{m}{s} }{\sqrt{1-\frac{0.5^2~c^2}{1^2~c^2} } }\\\\\Rightarrow p=2.89\times 10^{-19}~~kgms^{-1}\)

(c) For particle moving with speed 0.90c

v = 0.90c

the momentum of a proton would be,

\(\Rightarrow p=\frac{(1.67\times 10^{-27}kg)\times (0.90\times 3\times 10^8)\frac{m}{s} }{\sqrt{1-\frac{0.90^2~c^2}{1^2~c^2} } }\\\\\Rightarrow p=23.73\times 10^{-19}~~kgms^{-1}\)

Now, we need to convert answers into MeV/c

1 MeV = 1.6 × 10^(-13) kg.m²/s²

⇒ 1  kg.m²/s² = 625 × 10^(10) MeV

1 c = 299,792,458 m/s

⇒ 1 m/s = 3.3356E-9 c

So, 1  kg. m/s = 1.8737259e+21 MeV/c

(a) For p = 5.016 × 10^(-21) kgms^{-1}

⇒ p = 5.016 × 10^(-21) × 1.8737259e+21

⇒ p = 9.398 MeV/c

(b) For p = 2.89 × 10^(-19) kgms^{-1}

⇒ p = 2.89 × 10^(-19) × 1.8737259e+21

⇒ p = 541.5 MeV/c

(c) For p = 23.73 × 10^(-19) kgms^{-1}

⇒ p = 23.73 × 10^(-19) × 1.8737259e+21

⇒ p = 4446.35 MeV/c

Therefore, the momentum of a proton would be:

(a) For particle moving with speed 0.010c

p = 5.016 × 10^(-21) kgms^{-1}

p = 9.398 MeV/c

(b) For particle moving with speed 0.50c

p = 2.89 × 10^(-19) kgms^{-1}

p = 541.5 MeV/c

(c) For particle moving with speed 0.90c

p = 23.73 × 10^(-19) kgms^{-1}

p = 4446.35 MeV/c

Kenna will need 20 square feet of material for one flag. Thus, Kenna will need 100 square feet of material to make all five flags.

To determine the amount of material Kenna will need to make each flag and all five flags, we need to calculate the area of one flag and then multiply by five. Kenna's flag design is sketched on a coordinate plane, and assuming each grid mark represents a foot, we can count the number of squares enclosed by the flag design to determine its area. Counting the squares, we find that the flag design encloses 20 squares, which means that each flag will require 20 square feet of material. Multiplying 20 by 5, we find that Kenna will need a total of 100 square feet of material to make all five flags. Therefore, Kenna should purchase 100 square feet of material to make the racing flags for the car race.

John's family will travel 600 miles on the first day of their road trip to Florida.

To find the number of miles John's family will travel on the first day, we can use the formula:

distance = speed x time

We know that the total distance of the trip is 1,023 miles and the average driving speed is 60 miles per hour. So, if we can find the driving time on the first day, we can calculate the distance traveled on the first day.

We are given that the driving time on the first day is 10 hours. Therefore, the distance traveled on the first day can be found by:

distance = speed x time

distance = 60 miles/hour x 10 hours

distance = 600 miles

Therefore, the percent increase in temperature is approximately 65.44%.

The percent increase in temperature, we need to find the difference between the initial and final temperatures, divide that by the initial temperature, and then multiply by 100 to get a percentage:

Calculate the variation between the initial and end values. Subtract the beginning value from its absolute value. Add 100 to the result.  

Even in a low-emission scenario, the earth is predicted to rise by two degrees Celsius by 2050, suggesting that we might not be able to keep the Paris Agreement. Compared to the average temperature between 1850 and 1900, the global temperature has increased by 1.1°C.

percent increase = ((final temperature - initial temperature) / initial temperature) x 100

In this case:

percent increase = ((1034 - 625) / 625) x 100

percent increase = (409 / 625) x 100

percent increase = 65.44%

Based on the given informations, the change in y as t changes from 1 to 6 is approximately 3.870. Therefore the correct option is (A).

To find the change in y as t changes from 1 to 6, we need to integrate the given function with respect to t over the interval [1, 6] and then find the difference between the values of the integral at the two endpoints.

∫₁⁶ 6e\(.^{(-0.08(t-5)^2)}\)  dt

We can use the substitution u = t - 5 to simplify the integral:

∫₋₄¹ 6e\(.^{(-0.08u^2)}\)  du

Unfortunately, there is no closed-form solution for this integral. We can use numerical integration methods, such as Simpson's rule or the trapezoidal rule, to approximate the integral. Using Simpson's rule with a step size of 1, we get:

∫₋₄¹ 6e\(.^{(-0.08u^2)}\) du ≈ 3.870

Therefore, the change in y as t changes from 1 to 6 is approximately 3.870, which corresponds to option (A).

Answer:

A = 225\(\pi\) or A = 706.858

Step-by-step explanation:

The formula to find the area of a circle is A=\(\pi r^{2}\), with r being the radius.

In this case, 15 is your radius, so you just replace r with 15, like so:

A=\(\pi 15^{2}\), then simplify \(15^{2}\)

A = \(225\pi\)

From here you can leave the answer in its exact form, \(225\pi\), or you can simplify it by multiplying 225 times pi. In that case, your answer would be: 706.858 (rounded to the thousanths place).

If radius of a circle is 15 m then the area of circle is 225π square units.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Given that radius of a circle is 15m.

We have to find the area of the circle.

The formula for area of the circle is A=πr²

Given r is 15

Substitute r=15 in the area formula.

A=π(15)²

=π×15×15

=225π

Hence, if  radius of a circle is 15 m then the area of circle is 225π square units.

What is Vertically opposed angles?

Two lines intersecting at a point create vertical angles. Every time they are on an equal footing. Alternatively stated, four angles are created anytime two lines cross or intersect. Two opposed angles are equal and are referred to as vertical angles, as we can see. Due to their position opposite one another, they are also known as "Vertically opposed angles."

Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. The equality of the vertically opposed angles has been established.

To find the volume of the solid bounded by the paraboloid and the plane, we need to determine the limits of integration for x, y, and z.

The paraboloid is given by z = 2 - 4x^2 - 4y^2, and the plane is given by z = 1. We want to find the volume of the region where z is between the paraboloid and the plane, which means 1 ≤ z ≤ 2 - 4x^2 - 4y^2.

To determine the limits of integration for x and y, we need to find the boundaries of the region in the xy-plane where the paraboloid intersects the plane z = 1.

Setting z = 1 in the equation of the paraboloid, we have:

1 = 2 - 4x^2 - 4y^2

Simplifying, we get:

4x^2 + 4y^2 = 1

Dividing by 4, we have:

x^2 + y^2 = 1/4

This represents a circle centered at the origin with radius 1/2.

In polar coordinates, we can parameterize the circle as:

x = (1/2)cosθ

y = (1/2)sinθ

Now we can set up the integral to find the volume:

V = ∫∫∫ dz dA

The limits of integration for z are from z = 1 to z = 2 - 4x^2 - 4y^2.

The limits of integration for x and y are from -1/2 to 1/2 (since the circle has radius 1/2).

Therefore, the integral becomes:

V = ∫(∫(∫(1 to 2 - 4x^2 - 4y^2) dz) dA)

Converting to polar coordinates, the integral becomes:

V = ∫(∫(∫(1 to 2 - 4r^2) r dz) dr dθ)

Evaluating the innermost integral with respect to z, we get:

V = ∫(∫((2 - 4r^2 - r) dr) dθ)

Next, we integrate with respect to r:

V = ∫(2r - (4/3)r^3 - (1/2)r^2) dθ

Finally, we integrate with respect to θ from 0 to 2π:

V = ∫(2r - (4/3)r^3 - (1/2)r^2) dθ, θ = 0 to 2π

Evaluating this integral will give us the volume of the solid bounded by the paraboloid and the plane.

The values of Q(C1), Q(C2), and Q(C3) are 4, 4, and π, respectively.

The concept of the integral is a fundamental part of calculus and it is used to calculate the area under a curve or the volume of a 3-dimensional object. In this context, we will be exploring the integral of a two-dimensional set in the R^2 plane.

For every two-dimensional set C contained in R^2 for which the integral exists, the function Q(C) is defined as the double integral of the function (x^2 + y^2) over the set C. The double integral is a mathematical tool for finding the total volume under a surface.

Let's consider the three sets C1, C2, and C3 and find Q(C1), Q(C2), and Q(C3).

C1={(x,y) : −1 ≤ x ≤ 1, −1 ≤ y ≤ 1}

Q(C1) = ∬C1 (x^2 + y^2) dxdy = ∫^1_{-1}∫^1_{-1} (x^2 + y^2) dxdy = ∫^1_{-1} [(x^2 + y^2)/2]^1_{-1} dx = 4.

C2 ={(x,y):−1≤x≤1,−1≤y≤1}

Q(C2) = Q(C1) = 4.

C3 = {(x,y):x^2 + y^2 ≤1}

Q(C3) = ∬C3 (x^2 + y^2) dxdy = π.

In conclusion, the values of Q(C1), Q(C2), and Q(C3) are 4, 4, and π, respectively.
