Explanation:

Ransom E. Olds was the person who invented assembly line.

The assembly line method was the very first method to be used in automotive sector and was the prototype for which Henry Ford industries had developed his own. Henry Ford enhanced the design of assembly line through the use of a conveyor system's running platforms.

The assembly line has always been recognized as among the 20th century's greatest inventions. It so profoundly influenced the industrialized world that industries that didn't adopt the trend quickly became extinct and was one of the primary factors that helped to incorporate the automobile into American society.

A rock is thrown from the edge of the top of a 51 m tall building at some unknown angle above the horizontal. The rock strikes t

Xelga [282]

Answer:

The speed of projection is 34 m/s.

Explanation:

Height of building, h = 51 m

horizontal distance, d = 74 m

time, t = 8 s

Let the angle is A and the speed is u.

d = u cos A x t

74 = u cos A x 8

u cos A = 9.25 .... (1)

Use second equation of motion

$h = u sin A t - 0.5 gt^2\\\\-51 = u sinA \times 8 - 0.5\times 9.8\times8\times 8\\\\u sin A = 32.8 .... (2)$

Squaring and adding both the equations

$u^2 = 9.25^2 + 32.8^2 \\\\u = 34 m/s$

A certain organ pipe, open at both ends, produces a fundamental frequency of 288 Hz in air. Part A If the pipe is filled with he

alina1380 [7]

Answer:

773.25 Hz

Explanation:

Concept : In an open organ pipe in fundamental mode of vibration

wave length of wave λ = 2L

where L is length of the pipe

frequency = velocity of sound / λ

Given values: fundamental frequency = 288 Hz

fluid is air. velocity of sound = 340 m/s

⇒ 288 = 340/2L

⇒L = 59.02 cm

The point to be noted is if the pipe is filled with helium initially at the same temperature, there would be change in the sound velocity .Then, frequency of note produced will also be changed .

We know that velocity of sound is inversely proportional to square root of molar mass of gas

velocity of sound in air / velocity of sound in helium = Square root of (Molar mass of Helium/ molar mass of air)

$\frac{V_a}{V_{He}} = \sqrt{\frac{4}{28.8} } \\\frac{340}{V_{He}} =0.3725\\V_{He} =912.5 m/s$

Now, frequency = velocity of sound / λ

= 912.75 / (2 x 0.5902)

= 773.25 Hz

The length of a rectangle is four times its width. The perimeter of the rectangle is at most 130 cm. Which inequality models the

leva [86]

The answer would be the one where the left side is less than or equal to 130 because 130 has to be the greatest value and the value of the w's cannot exceed 130, but they can equal it

How far apart are the fringes in the center of the pattern on a screen 4.3 m away? Express your answer to two significant figure

attashe74 [19]

Answer:

d = $\frac{nLembda}{sin(theta)}$

Explanation:

This comes from diffrection pattern equation used to locate fringe pattern, i will explain every variable in it here.

n = order of fringe = 0 1 2 3 .. and negative integars as well.

d is sacing between slits.

Theta = angle at which light-Ray is directed towards fringe.

It appears that the distance between consectice fringes would same as the distance between two slits 'd'.

therefore calculating that distance should give us the distance between two fringe patters.

Note we don't use transversal seperation distance here.

How do atoms join together?

miv72 [106K]

Answer:

Atoms can be joined together by chemical bonds.

Explanation:

When atoms form bonds, they can achieve a stable electron arrangement. To achieve a stable electron arrangement atoms can lose, gain or share electrons. There are many different types of bonds that hold atoms together.
