The Second Industrial Revolution was another great leap forward in technology and society. New innovations in steel production, petroleum and electricity led to the introduction of public automobiles and airplanes. You wanna know how everything began? Let's see
The Second Industrial Revolution, which began in the middle of 19th century (1850-1970). It was a period of growth for pre-existing industries and expansion of new ones; such as the steel, oil and electricity fields. The development of new technologies led to the introduction of two things that would change the world: public transport and planes.
During the Second Industrial Revolution, the existing manufacturing and production methods were improve. For instance, steel replaced iron in the building business. It was strong and it was cheap. So, it made possible to build rail lines at competitive cost and spread transportation. Steel also facilitated the construction of ships, skyscrapers and larger bridges.
Steel displaced iron because it was stronger and cheaper
Although the Second Industrial Revolution happened just a few years after the first Industrial Revolution, it was as big of a leap forward as its predecessor. If you are reading this now, surely you can't imagine a world without electricity! But at the time of the Second Industrial Revolution, this was the norm.
Faraday started playing with the idea of electricity. Then, a few years later, Edison and Swan perfected their design of a lightbulb which was practical for home use.
This, in addition to the appearance of the first efficient commercial electrical generators in the 1870s, made public electricity possible.
Swan took his incandescent lightbulbs to England. The English used Swan's lightbulbs to light Mosley Street in Newcastle upon Tyne. So, this was the first electrical street lighting installation in the world. Then, Swan gifted the Savoy Theatre in London with 1,200 of his lightbulbs. Thus making it the first public building to be lit entirely by electricity.
Mosley Street and the Savoy Theatre set the stage for the first large-scale power station. It was located at the Holborn Viaduct in London. Then followed the power station at Pearl Street in New York. Afterwards, Sebastian de Ferranti thought of "stepping down" high-voltage alternating current. De Ferranti's idea enabled the assembly line and mass production.

Answer:

Step-by-step explanation:
−5x + y = −3
3x − 8y = 24
Answer:
x = 0
y = -3
Step-by-step explanation:
-5x + y = -3 --------------(I)
3x - 8y = 24 ------------(II)
Multiply the equation (I) by 8
(I)*8 - 40x + 8y = -24
(II) 3x - 8y = 24 {Add and y will be eliminated}
-37x = 0
x = 0
Plugin x = 0 in equation(I)
-5*0 + y = -3
0 + y = -3
y = -3
Answer:
- 5x + y =-3 ......1
3x -8y = 24.........2
eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3
-40 x +8 y =-24 ...........3
3 x - 8y = 24 ......... 2
·································
-37 x +0 = 0
··························
x =0
put x = 0 in equation 2
3 x -8 y =24
3×0 -8 y = 24
0 -8 y=24
-y =24÷8
-y =3
y = -3
ans ;
x = 0
y = -3

hello again
Step-by-step explanation:
the radius of the circle is 6mm
for having the circumference we need diameter
for having diameter we should multiply in 2
so:
[tex]d = 2r \\ \\ d = 2 \times 6 = 12mm \\ v = \pi \: d \\ v = 12\pi \: mm[/tex]
i hope this is the answer
A number raised to the power of 4 is equal to 625. Determine the number
Answer:
Step-by-step explanation:
[tex]n^4=625\\ \\ \sqrt[4]{n^4}=\sqrt[4]{625}\\ \\ n=5[/tex]
Answer:
5
Step-by-step explanation:
i started big the broke it down:
25*25=625 so that didnt work
so i went to 15
15*15=225*15=3375 and that also didnt work
so i went to 5
5*5=25*5=125*5=625

Which of the following is a correct method to verify that two functions
are INVERSES of each other?
the graphs of the functions are a reflection across the line y = -x.
the graphs of the functions are a reflections across the y axis.
the graphs of the functions are a reflection across the line, y = x.
O The correct or complete answer is not in any of the choices.
Answer:
C) the graphs of the function are a reflection across the line, y = x
Step-by-step explanation:
Inverse functions have graphs that are reflections over the line y = x and thus have reversed ordered pairs.
HOPE THIS HELPS!!!! <33333
-Silver
When that two functions are INVERSES of each other then
The graphs of the functions are a reflection across the line y = x
Option C
Given :
The two functions that are inverse to each other
When two functions are inverse to each other then
the domain of function f is the range of inverse function
The range of function f is the domain of inverse function
x values of function f = y values of inverse function
y values of function f = x values of inverse function
Hence we can say that the graph of function are reflection across y=x
The graphs of the functions are a reflection across the line y = x

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of length to width 5 to 3, what is the value of x
Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:
[tex]\frac{L}{W}=\frac{5}{3}[/tex]
Where:
L represents the new length W represents the new widthNow, we know that each dimension is reduced by x inches, it means:
[tex]L=18-x[/tex]
[tex]W=12-x[/tex]
Then, we will have:
[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]
Finally, we just need to solve it for x.
[tex]3(18-x)=5(12-x)[/tex]
[tex]5x-3x=60-54[/tex]
[tex]2x=6[/tex]
[tex]x=3[/tex]
Therefore, the value of x = 3.
I hope it helps you!

A meal that cost $50 had a 20% tip and 5% sales tax. How could you calculate your final total bill?
Answer:
$57.50
Step-by-step explanation:
find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5
