East Germany lagged behind in technology

MatroZZZ [7]

Answer:

C. West Germany

Explanation:

What are industries located near harbours where raw materials are imported called?<br>

Alona [7]

The industries located near harbors where raw materials are imported called iron and steel industries.

The industry is the institution of productive corporations or organizations that produce or deliver items, offerings, or assets of income. In economics, industries are generally classified as primary, secondary, tertiary, and quaternary; secondary industries are in addition labeled as heavy and light.

In macroeconomics, an enterprise is a branch of a financial system that produces a closely-associated set of raw substances, goods, or offerings. as an example, one would possibly seek advice from the wood enterprise or the coverage industry.

The definition of an industry is any large-scale business hobby or a sort of efficient manufacture or change. An example of an industry is the coal mining business.

. If the fastest passenger aircraft can fly 0.45 km/s (1000 mph), how long would it take to reach the sun? The galactic center?

nadezda [96]

Answer:

The passenger aircraft would take 10.542 years to reach the Sun from the Earth.

The passenger aircraft would take $1.733\times 10^{10}$ years to reach the gallactic center.

Explanation:

The distance to the sun from the Earth is approximately equal to $1.496\times 10^{8}\,km$ , if the passenger travels at constant speed, then the time needed to reach the sun is calculated by the following kinematic formula:

$\Delta t = \frac{s}{v}$ (1)

Where:

$s$ - Travelled distance, measured in kilometers.

$v$ - Speed of the passenger aircraft, measured in kilometers per second.

$\Delta t$ - Travelling time, measured in seconds.

If we know that $s = 1.496\times 10^{8}\,km$ and $v = 0.45\,\frac{km}{s}$ , then the travelling time is:

$\Delta t = \frac{1.496\times 10^{8}\,km}{0.45\,\frac{km}{h} }$

$\Delta t = 3.324\times 10^{8}\,s$

$\Delta t = 3847.736\,days$

$\Delta t = 10.542\,years$

The passenger aircraft would take 10.542 years to reach the Sun from the Earth.

The distance between the Earth and the galactic center is approximately equal to $2.460\times 10^{17}\,km$ . If the passenger travels at constant speed and if we know that $s = 2.460\times 10^{17}\,km$ and $v = 0.45\,\frac{km}{s}$ , then the travelling time is:

$\Delta t = \frac{2.460\times 10^{17}\,km}{0.45\,\frac{km}{s} }$

$\Delta t = 5.467\times 10^{17}\,s$

$\Delta t = 6.327\times 10^{12}\,days$

$\Delta t = 1.733\times 10^{10}\,years$

The passenger aircraft would take $1.733\times 10^{10}$ years to reach the gallactic center.
