Is there ice on the moon?

Geography
1 answer:
k0ka [10]3 years ago

Liquid water cannot persist at the moon's surface, and water vapor is decomposed by sunlight, with hydrogen quickly lost to outer space. However, scientists have since the 1960s conjectured that water ice could survive in cold, permanently shadowed craters at the Moon's poles.

following independence from the soviet union in the 1990s , the new leaders of central asia tried to?
Hoochie [10]

The leaders of Central Asia tried to gain full power of the countries in this region when they gained independence.

Once the countries of Central Asia, popularly called the Stans, gained independence from the Soviet Union, the new leaders quickly tried to establish themselves as absolute leaders in their respective countries. The methods were actually very similar to those used in the Soviet Union, which was weird as they tried to get out of that political system.

The leaders of Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan, and Tajikistan, all continued to rule in a socialist manner, and the leaders that got power when they got independence are still in power.

While Kazakhstan is somewhat changing its direction gradually and becomes more modern country little by little, the likes of Uzbekistan and Turkmenistan are very similar to North Korea in many ways.

What is the predominant climate of South America
PolarNik [594]

South America is a continent that has a variety of climates, but the predominant one is the tropical climate.

The tropical climates are climates that appear on and in close proximity tot he Equator, and they are not monotone, but instead differ from one another. From the tropical climates that dominate the South American continent, the most widespread are the tropical rainforest and the tropical grasslands, which account for most of the tropical climates, with the tropical semiarid and tropical arid climates occupying much smaller areas on the continent, mostly alongside the Pacific coastline.

The Amazon rainforest is the trademark of South America, and it is the biggest tropical rainforest in the world, occupying huge portion of the northern half of the continent, with the tropical grasslands occupying large ares both north and south of the Amazon.

. 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.
