Las dos torres que sostienen un puente colgante tienen una separación de 240m y una altura de 110m a partir de la carretera, si el cable tensor más corto mide 10m, ¿cuál es altura de un cable que se encuentra a 100m de distancia del centro?
La altura es de 169.4 metros.
Dado que las dos torres que sostienen un puente colgante tienen una separación de 240m y una altura de 110m a partir de la carretera, si el cable tensor más corto mide 10m, para determinar cuál es altura de un cable que se encuentra a 100m de distancia del centro se debe realizar los siguientes cálculos, aplicando la ecuación parabólica:
(240)² = 4P x (110-10)57600 = 4P x 10057600 = 400P57600/400 = P144 = P 200 x 200 = 4 x 144 x (Altura - 100) 40000 = 576Altura - 57600 40000 + 57600 / 576 = Altura 169.4 metros = Altura
Por lo tanto, la altura es de 169.4 metros.

Answer:
A. 15 cm²
B. 15 cm²
Explanation:
A. Original FormulaThe diagram shows the values of a, b, h. Put these in the original formula to find the area.
A = 0.5(a+b)h
A = 0.5(3 +7 cm)(3 cm) = 0.5(10 cm)(3 cm) = 15 cm²
__
B. Splitting MethodThe base of each triangle is half the difference between the two base lengths.
triangle base = (7 -3)/2 = 2 . . . cm
The area of a triangle is given by the formula ...
A = 0.5bh
A = 0.5(2 cm)(3 cm) = 3 cm²
The area of the central rectangle is given by ...
A = bh
A = (3 cm)(3 cm) = 9 cm²
Then the area of the trapezium is ...
A(triangle) +A(triangle) +A(rectangle) = A(trapezium)
(3 cm²) +(3 cm²) +(9 cm²) = A(trapezium) = 15 cm²
A positively charged electric has a charge of 2 Coulombs. If 12.5x10^18 free electrons are added to it, what will be the net charge on the said dielectric?
The net charge on the said dielectric is 0
1C = 6.25 * 10¹⁸ electrons; hence:
-12.5x10¹⁸ free electrons = (-12.5x10¹⁸ free electrons * (1C/ 6.25 * 10¹⁸ electrons))
-12.5x10¹⁸ free electrons = -2 C
A positively charged electric has a charge of 2 Coulombs, hence:
Q₁ = 2C
12.5x10¹⁸ free electrons are added to it, hence:
Q₂ = -2C

Internal combustion engine is dependent on the heat of combustion so as to make torque to move the vehicle and power the system.
A lot of heat made during combustion is not often used productively and therefore need to be removed to avoid overheating of the engine.
The heat energy that is not used for is wasted in three ways: They are:
About 33% is wasted by being dumped straight out of the exhaust to the atmosphere. About 33% is wasted by the cooling system, which prevents overheating of the engine components.

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.

Assume that you have a wireless application you would like to design,build and sell as a commercial product.You have selected a target frequency in the UHF range.How would you decide what frequency to use and how would you get permission to use it ?
The frequency to use depends on the range and distance of signal transmission. There is government communication agency in charge of issuing license in order to get carrier frequency in which the application can work with.
UHF means Ultra - high frequencies which is mostly used in television broadcasting and mobile phone. Frequency range of the UHF is between 300MHz to 3GHz.
Assuming that you have a wireless application you would like to design, build and sell as a commercial product. And you have selected a target frequency in the UHF range.
Most wireless applications make use of radio wave and microwave depending on the range of distance in which the signal will travel.
The first thing to do is to determine the distance. Whether is short or long distance.Then get a license from the right government communication agency so that a carrier wave frequency will be allocated for you.

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.
