The locus of a point on the circumference of a circle as it rolls without slipping on a straight line is called a cycloid. In this case, the circle has a diameter of 46mm and makes 1½ revolutions.
To understand how the locus is formed, imagine a point P on the circumference of the rolling circle. As the circle rolls without slipping, point P traces a path on the ground.
To determine the shape of this path, we can divide the rolling motion into two parts: the horizontal and vertical components.
1. Horizontal Component:
During each revolution, the point P moves a distance equal to the circumference of the circle, which is π times the diameter. In this case, the diameter is 46mm, so the circumference is 46π mm.
Since the circle makes 1½ revolutions, the total horizontal distance covered by point P is 1½ times the circumference of the circle, which is 1½ * 46π mm.
2. Vertical Component:
The vertical distance covered by point P is equal to the diameter of the circle, which is 46mm.
Combining the horizontal and vertical components, we can plot the locus of point P. Each point on the locus represents the position of point P as the circle rolls.
To draw the locus, we can start by marking the initial position of point P at the starting point of the rolling circle. From there, we can calculate the coordinates of point P at regular intervals, corresponding to the distances covered by the circle.
For example, if we divide the total horizontal distance covered by point P into 10 equal intervals, we can calculate the x-coordinate for each interval by dividing the total distance by 10.
Similarly, since the vertical distance remains constant, the y-coordinate of point P remains the same throughout.
By plotting these coordinates, we can trace the shape of the locus of point P as a cycloid.
I hope this helps you. :)

A bicycle with 540mm wheel diameter passes over a segment arched culvert of radius 760mm. draw the locus of a point on the circumference of the wheel when it makes one complete revolution
Answers
In order to draw the locus, we can construct a circle with a radius of 1696.62mm centered at the center of the culvert.
How to calculate the valueThe diameter of the wheel is given as 540mm, so the radius of the wheel is half of that: 540mm / 2 = 270mm. The circumference of the wheel can be calculated as 2π times the radius: 2π × 270mm
≈ 1696.62mm.
Since the circumference of the wheel is approximately 1696.62mm and point P traces out a circle, the locus of point P will be a circle with a circumference of 1696.62mm.
Hence, to draw the locus, we can construct a circle with a radius of 1696.62mm centered at the center of the culvert.

Almost all collisions are due to driver error

The statement "almost all collisions are due to driver error" is absolutely false.
What are the major reasons for collisions on road?The major reasons for collisions on road are as follows:
Overspeed.Distractions to drivers by passengers.Mix driving with drinking.Not appropriately following the rules of traffic.Avoiding Safety Gear like Seat belts and Helmets.Non-adherence to lane driving and overtaking in a wrong manner.With the help of the above reasons for collisions on road, it is clear that in all cases, only the driver is not responsible for road accidents. But yeah, most of the time driver is responsible for the same.
But sometimes, the driver is not faulty in any circumstances, still, he/she faces strong criticism for the fact that the driver is not driving the vehicle properly.

He found this was not a good option after all. Which explanation most logically explains why the steel was not optimal for this project?
A) Steel becomes too hot in the sun and can burn the children.
B) Steel is a composite material, and these rarely work well when building prototypes.
C) Steel is too malleable and therefore not sturdy enough.
D) Steel is an inorganic material, and these are rarely efficient.
Answers
Answer:
The correct option is;
A) Steel becomes too hot in the Sun and can burn the children
Explanation:
The properties of steel includes;
Low specific heat capacity, high thermal and electrical toughness, high hardness, high tensile strength, high yield strength, appreciable elongation, high fatigue strength, can easily corrode, high malleability and ability to creep
Therefore, due to the low specific heat capacity, which is 0.511 J/(g·°C) and high conductivity of steel which is about 32 W/(m·k), the temperature of the steel can rapidly rise and the hot steel surface can readily conduct the heat, (due to the temperature difference) to other bodies that come in contact

The question states that x has is value in between and including 1.9 and 2.1. So the number is greater than or equal to 1.9 but less than or equal to 2.1.
In option A \(x\geq 2.1\) this means that the value of x is greater than or equal to 2.1 which does not satisfy the condition mentioned in the question
In option D \(x\) is greater than or equal to 2.1 but less than or equal to 1.9 which does not satisfy the condition mentioned in the question.
In option C \(x\) is greater than or equal to 1.9 and less than or equal to 2.1 which does satisfy the condition mentioned in the question.

a. What percent of tart cherries are produced in this state?

Answers
Answer:
Percent of not tart cherries = 21%
Explanation:
Given:
Production of cherry tart = 79
Find:
Percent of tart cherries
Percent of not tart cherries
Computation:
Percent of tart cherries = Production of cherry tart[100% / 100]
Percent of tart cherries = 79[100% / 100]
Percent of tart cherries = 79%
Percent of not tart cherries = 100% - Percent of tart cherries
Percent of not tart cherries = 100% - 79%
Percent of not tart cherries = 21%

The magnetic field at a point P whose coordinates are P (0, 0, d) is 2μi/3πd
What is magnetic field?A magnetic field is the region where the effect of a magnetic force is felt.
How to find the magnetic field at P?First, we need to find the magnetic field due to each wire, then we find the resultant magnetic field at P
Magnitude of the magnetic field on a wireThe magnitude of the magnetic field on each wire is given by B = μi/2πr where
μ = permeability of free space, i = current and r = distance of point from wire.Magnetic field in current i/3 in positive y direction at PGiven that
i = i/3 and r = d, we have thatB₁ = μ(i/3)/2πd
= μi/6πd
Magnetic field in current i/3 in negative y direction at PGiven that
i = -i/3 and r = d, we have thatB₂ = μ(i/3)/2πd
= -μi/6πd
The net magnetic field in the y- direction at PB' = B₁ + B₂
= μi/6πd - μi/6πd
= 0
Magnetic field in current i/3 in positive x direction at PGiven that
i = i/3 and r = d, we have thatB₃ = μ(i/3)/2πd
= μi/6πd
Magnetic field in current i in positive y direction at PGiven that
i = i and r = d, we have thatB₄ = μi//2πd
The net magnetic field in the x- direction at PB" = B + B
= μi/6πd + μi/2πd
= μ(i + 3i)/6πd
= μ4i/6πd
= 2μi/3πd
The net magnetic field at PSo, the net magnetic field at P is B = B' + B"
Since
B' = 0 and B" = 2μi/3πdB = B' + B"
= 0 + B
= B"
= 2μi/3πd
So, the magnetic field at a point P whose coordinates are P (0, 0, d) is 2μi/3πd
