and particle 2 is " gaining " at a rate of (10/7)m/s leftward ; this is their relative velocity at that time . Thus , this "gap" of 23cm between them will be closed after an additional time of (0.23m)/(10/7m/s)=0.16s has passed . At this time (t=0.82+0.16=0.98s) the two particles are at x=(−2/7)(0.98)=−28cm

The purpose of the red-core yarns in the synthetic sling is to detect the strength loss and also to reveal the damage in the red corn yarns.
What is synthetic sling?Lifting slings constructed of synthetic materials like nylon or polyester are known as synthetic slings. These kinds of slings, which can also be called synthetic lifting straps or synthetic rigging slings, are thin, flexible, and protected by a jacket.
Sling Webbing features red core yarns to visibly indicate damage and serve as a reason for sling rejection because of this. Synthetic sling are flexible.
Therefore, it can be concluded that The red-core yarns in the synthetic sling are used to both reveal and detect strength loss in the red maize yarns. It also acts as the basis for sling rejection.

O D. Horsepower; torque; torque
Clear my choice
Answer:
C
Explanation:
As horsepower is the rate at which that force torque is a twisting or turning force, horsepower is produced. Hence option C is correct.
What is horsepower?Horsepower is defined as a unit used to describe the pace at which labor is done or to quantify power, frequently in relation to the output of engines or motors. Standardization and types of horsepower vary widely. A car's engine power is measured in horsepower (hp); the greater the number, the more power is transferred to the wheels and, in theory, the faster it will travel.
To put it simply, horsepower is your overall speed and power, whereas torque allows you to feel the sensation of acceleration when you put your foot down. When you realize that horsepower is derived from torque, this makes sense. Torque is a unit of rotational or twisting force. The power an engine produces is referred to as horsepower.
Thus, as horsepower is the rate at which that force torque is a twisting or turning force, horsepower is produced. Hence option C is correct.

. What is wrought iron? Discuss in brief its chemical composition, properties and applications.
Answer:
Wrought iron is an iron alloy with very low carbon content with respect to cast iron.
Explanation:
It is soft, ductile, magnetic, and has high elasticity and tensile strength. It can be heated and reheated and worked into various shapes.
Answer:
Wrought iron is an ferrous metal with a very low amount of carbon (less than 0.08%) compared to cast iron (2% or more). It is a semi-molten mass of iron with a fibrous sheath (up to 2% by weight), giving it a "grain" similar to wood grain, visible when bent or bent to the point of fracture. Wrought iron, malleable, easy to draw, corrosion resistant and easy to weld. Explanation:
An egg with an initial temperature 25C was place into a boiling water for 15 minutes. Heat from the boiling water enters the egg and changes its temperature gradually over time and space. Using the 2 dimensional finite element method, prove that the temperature of the egg varies from the shell to the center of the egg. You may need to develop your own nodes before start deriving the equations.
It is proved from the below that the temperature of the egg varies from the shell to the center of the egg.
Using the 2-dimensional finite element method, we will need to find the Biot number of the system by using the formula:
[tex]\mathbf{Bi = \dfrac{h_c r_o}{k} }[/tex]
According to the Heisler chart, the curves in the graph represent a range of values for the inverse of the Biot number,
where;
[tex]\mathbf{Bi = \dfrac{h_c r_o}{k} }[/tex]
here;
k = the material's thermal conductivity h = the heat transfer coefficient.By developing nodes based on assumptions;
[tex]\mathbf{Bi = \dfrac{1700 \times 0.025}{0.682} }[/tex]
Bi = 62.32
The inverse of Biot number is:
[tex]\mathbf{=\dfrac{1}{Bi}}[/tex]
[tex]\mathbf{=\dfrac{1}{62.32}}[/tex]
= 0.016
Similarly, the Fourier number [tex]\mathbf{F_o}}[/tex] is calculated by using the expression;
[tex]\mathbf{F_o = \dfrac{\alpha t }{r_o^2} }[/tex]
[tex]\mathbf{F_o = \dfrac{k t }{\rho c_pr_o^2} }[/tex]
where;
time (t) = 15 mins = (15 × 60) sec[tex]\mathbf{F_o = \dfrac{0.682 \times 15 \times 60 }{958.4 \times 4211 \times 0.025^2} }[/tex]
[tex]\mathbf{F_o = 0.243}[/tex]
Using the 2-dimensional finite element method, the temperature ratio is:
[tex]\mathbf{\dfrac{T(0,t) -T_{\infty}}{T_o -T_{\infty}} = 0.1 }[/tex]
T(0,t) = 100 + 0.1(4-100)
T(0,t) = 100 + 0.1(-96)
T(0,t) = 100 - 9.6
T(0, t) = 90.4° C
Therefore, we can conclude that it is proved that the temperature of the egg varies from the shell to the center of the egg.
