A car travels from A, due north to a town B 4 km away. It then travels due east until it arrives town C 5 km from B. determine the distance of town C from A
Answers
Answer:
A to C = 6.4 km
Explanation:
A to B = 4 km
B to C = 5 km
A to C = using pythagorean theorem
a² + b² = c²
a = A to B = 4
b = B to C = 5
c = A to C
c² = 4² + 5²
c = 6.4 km (A to C)
According to the scenario, the distance between town C from town A is found to be 6.40 Km.
Which background does this question depend on?The background that this question depends on is known as the direction-based question. These types of questions completely depend on the distance of moving bodies like cars, persons, or any other objects as well with respect to the initial position.
According to the question,
The distance between town A to town B = 4 km.
The distance between town B to town C = 5 km.
Now, according to the Pythagoras theorem, the distance between town C to town A is as follows:
\(AC^2\) = \(AB^2 +BC^2\).
\(AC^2\) = \(4^2+5^2\)
\(AC^2\) = 16 + 25 = 41.
AC = √41 = 6.40 km.
Therefore, the distance between town C from town A is found to be 6.40 Km.

consider the simplified beam model of a ship heaving in waves on the open seas. in this model, the beam is subjected to an upwards (positive y) loading of uniform value on the left-half (0
Answers
In the simplified beam model of a ship heaving in waves, the beam experiences a uniform upward loading on the left-half and a uniform downward loading on the right-half, resulting in a deflection profile and stress distribution.
The step-by-step explanation of this model involves determining the beam deflection and stress distribution.
First, we analyze the left-half of the beam subjected to the upward loading. Using the Euler-Bernoulli beam theory, we calculate the beam deflection equation and apply the boundary conditions to solve for the constants of integration. This provides the deflection profile for the left-half of the beam.
Next, we analyze the right-half of the beam subjected to the downward loading. Following the same procedure, we obtain the deflection equation for the right-half and solve for the constants of integration using the appropriate boundary conditions.
By combining the deflection equations of the left and right halves, we obtain the complete deflection profile of the beam. Additionally, we can determine the stress distribution by considering the bending moment and moment-curvature relationship.
Overall, the simplified beam model allows us to study the behavior of a ship's beam when heaving in waves, considering the uniform loading distribution. This analysis provides insights into the deflection and stress experienced by the beam under such conditions.

the torque is required to rotate the inner cylinder at 12 r min, the outer cylinder remaining stationary is 11.0807 N-m.
we have left out some other important details, such as the time required to reach that rpm, whether the beginning state is at rest, and the axis around which the cylinder is revolving. However, we'll suppose that it will be 60 seconds (time is necessary to convert rpm to angular acceleration)
rotation around the center axis
Angular acceleration = torque + MOI
Currently, angular acceleration equals 2 rpm/(t 60).
In order to avoid getting an extremely high figure, we estimated that the diameter of the cylinder was 600 mm rather than 600 meters: angular acceleration= 1.047 rad/s² MOI for cylinder across center dia= 1/4MR²+ 1/12ML²
MOI= 10.5833 kg-m

Determine the force and moment reactions at the support A of the built-in beam which is subjected to the sine-wave load distribution. The force reaction RA is positive if upward, negative if downward. The moment reaction MA is positive if counterclockwise, negative if clockwise.
Answers
Answer:
\(R_A=\frac{2w_0l}{\pi}\)
\(M_A=\frac{w_0l^2}{\pi}\)
Explanation:
The beam is subjected to the sine-wave load distribution as shown in the figure.
As the beam is in equilibrium condition, so net force and moment in any direction are zero.
Assuming the length, \(l\), of the beam is along the x-axis and the loading direction is along the y-axis.
The load density, w, per unit length, at a distance of x from the point A, for the sine-wave load is
\(w=w_0\sin\left(\frac{\pi}{l}x\right)\),
where \(w_0\) is constant (maximum load density)
\(R_A\) is positive if upward, so w is negative as it is acting in the downward direction.
A small force, dF, in the downward direction, due to load on a small element dx at a distance of x from the point A is
\(dF=wdx\) in the downward direction
\(\Rightarrow dF=-w_0\sin\left(\frac{\pi}{l}x\right)dx\cdots(i)\)
The moment, dM about point A, due to small force, dF, is
\(dM=(dF)x\)
As the moment in the clockwise direction is negative, so
\(dM=-(dF)x \cdots(ii)\)
\(\Rightarrow dM=w_0\sin\left(\frac{\pi}{l}x\right)xdx\cdots(i)\)
At equilibrium state, net force along the y-direction will be zero, i.e
\(\Sigma F_y=0\)
\(\Rightarrow R_A+\int_{0}^{l}dF=0\)
\(\Rightarrow R_A=-\int_{0}^{l}dF\cdots(iii)\)
From equation (i)
\(\int_{0}^{l}dF=\int_{0}^{l}w_0\sin\left(\frac{\pi}{l}x\right)dx\)
\(\Rightarrow F=\int_{0}^{l}w_0\sin\left(\frac{\pi}{l}x\right)dx\)
\(=-\left[\frac{lw_0}{\pi}\cos\left(\frac{\pi}{l}x\right)\right]_0^l\)
\(=-\frac{l}{\pi}w_0(-1-1)\)
\(\Rightarrow F=\frac{2w_0l}{\pi}\cdots(iv)\)
The center of F is at the centroid of the sine-curve in the downward direction.
Putting this value in the equation (iii), we have
\(R_A=\frac{2w_0l}{\pi}\)
Again, at the equilibrium state, net force along the y-direction will be zero, i.e
\(M_A+\int_{0}^{l}dM=0\)
\(\Rightarrow M_A-\int_{0}^{l}(dF)x=0\) [from (ii)]
\(\Rightarrow M_A=\int_{0}^{l}\left\(dF)x\)
\(\Rightarrow M_A=F \bar{x}\)
Where \(\bar{x}\) is the x-coordinate of the centroid.
Due to symmetry, \(\bar{x}=\frac l 2\)
So, \(M_A=F\times \frac l 2\)
\(\Rightarrow M_A=\frac{2w_0l}{\pi}\times \frac l 2\) [ using (iv)]
\(\Rightarrow M_A=\frac{w_0l^2}{\pi}\)
Hence, the reaction force and the moment at point A are
\(R_A=\frac{2w_0l}{\pi}\)
\(M_A=\frac{w_0l^2}{\pi}\)

Another manufacturer offers a unit that is actually two LEDs, one that emits red light with a wavelength of 630 nm, the other emits green light with a 540 nm wavelength. The yellow light from both LEDs looks identical when shined on a wall.
Suppose that each type of LED was used to shine light through a diffraction grating. In each case, there will be a pattern that appears on the screen. Describe the differences (if any) between those patterns as completely as you can.
Answers
Answer:
The light from the first LED will appear as yellow while the light from the second LED won't appear as Yellow light when passed through a diffraction grating
Explanation:
There are two types of LED's
First LED emits only yellow light with wavelength of 590 nm
Second LED : emits red light with wavelength of 630 nm and emits green light with a 540 nm wavelength
The second LED produces a yellow light because of the mixture of red and green lights
therefore when the light from the SECOND LED is passed through a diffraction grating, the light is split into its components ( i,e green and red lights ) this is because the lights are not on the same wavelength
A plant has ten machines and currently operates two 8-hr shift per day, 5 days per week, 50 weeks per year. the ten machines produce the same part each at a rate of 30 pc/hr. (a) determine annual production capacity of this plant. (b) if the plant were to operate three 8-hr shifts per day, 6 days per week, 51 weeks per year, determine the annual percentage increase in plant capacity
Answers
Answer:
83.6%
Explanation:
(a)On its current schedule, the plant can theoretically produce ...
(30 pc/h/machine)(10 machine)(8 h/shift)(2 shift/day)(5 day/wk)(50 wk/yr)
= (30)(10)(8)(2)(5)(50) pc/yr = 1,200,000 pc/yr
__
(b)On the proposed schedule, this production becomes ...
(30 pc/mach)(10 mach)(8 h/sh)(3 sh/da)(6 da/wk)(51 wk/yr)
= (30)(10)(8)(3)(6)(51) pc/yr = 2,203,200 pc/yr
The increase in capacity is ...
(2,203,200/1,200,000 -1) × 100% = 83.6% . . . capacity increase
_____
Additional comment
The number of parts per shift did not change. Only the number of shifts per year changed. It went up by a factor of (3/2)(6/5)(51/50) = 1.836. Hence the 83.6% increase in capacity.
We have to assume that maintenance and repair are done as effectvely as before in the reduced down time that each machine has.

\(F = G * m1 * m2 / r^2\)
\(m = rho * (4/3) * pi * r^3\)
r = 65 mm = 0.065 m
a = 3.7r = 0.241 m
b = 2.1r = 0.137 m
c = 0.6r = 0.039 m
m_copper = rho_copper \(* (4/3) * pi * r^3\)
\(= 8,960 kg/m^3 * (4/3) * pi * (0.065 m)^3\)
= 0.0138 kg
m_steel = rho_steel \(* (4/3) * pi * r^3\)
= \(7,860 kg/m^3 * (4/3) * pi * (0.065 m)^3\)
= 0.0119 kg
F = G m_copper m_steel / \(r^2\)

optimal mix of output
the most desirable combination of output attainable with existing resources, technology, and social values
Answers
The optimal mix of output is the most desirable combination of output attainable with existing resources, technology, and social values. It is the result of the interaction between the input and output markets that operate within an economy.
An optimal mix of output occurs when the level of production results in the maximum possible satisfaction of the population's needs and wants. It is often used to describe the balance between the output of goods and services in a specific market or the economy as a whole. It is a critical concept in economic theory because it determines the level of economic growth and development that can be achieved in a given period.
The optimal mix of output is also determined by the allocation of resources. Scarce resources must be allocated efficiently to produce goods and services that are in high demand and have a significant impact on social welfare. The efficient allocation of resources is one of the key determinants of economic growth and development. Economists refer to this process as the "allocation of resources."
The optimal mix of output can be affected by changes in the market, such as changes in technology or consumer preferences. These changes can affect the optimal mix of output by creating new opportunities for producers to introduce new products or services.
Changes in consumer preferences can also change the optimal mix of output as producers shift production to meet the changing needs of consumers.

What makes it challenging to build new nuclear power stations in the UK?
Answers
One of the major reasons is the high cost associated with the construction of new nuclear plants.
The construction and operation of nuclear plants require a significant amount of capital investment, which makes it difficult for investors to take the risk. Additionally, the high cost of decommissioning nuclear plants and the disposal of radioactive waste is also a major concern.
Another challenge associated with building new nuclear power stations is public opposition. Many people are skeptical about the safety of nuclear power, especially after incidents like in Japan. This has led to protests and campaigns against the construction of new nuclear plants, making it difficult for the government to get public support.
The lengthy regulatory process is also a major challenge in building new nuclear power stations in the UK. The approval process involves multiple stages and can take several years to complete. This results in significant delays and increased costs.
Furthermore, the lack of skilled labor and expertise in the nuclear industry is also a challenge. Many of the skilled workers in the industry are approaching retirement age, and there is a shortage of new workers to replace them.
In conclusion, building new nuclear power stations in the UK is a challenging task due to high costs, public opposition, regulatory hurdles, and a shortage of skilled workers. Addressing these challenges will be essential for the successful development of new nuclear power stations in the future.
