Galaxies are spread around each other with an average of a few mega-parsec apart(which is a unit of length to measure large distances to astronomical objects). At a distance of about 2.5 million light years, the Andromeda galaxy) which happens to be the closest spiral galaxy to the Milky Way.


The galaxies are so far apart because space keeps expanding.

Propose 4 reasons why society should support scientific research (use an example to support each of your reasons).
Andrei [34K]

Answer:

Scientific research can promote the raise of the productivity of the society.Which means it can help people produce more goods in a much shorter time and better quality.

From the perspective of a country, if scientific research will not be supported, that country will face a highly pressure and threaten from other counties due to the technology advancement.Technology development will largely determine the military and economic power of a country.

From personally view,our next generation need to be good educated with support.A large part of the area will focus on scientific research,so if we want our children to perform better than us and create a better future.We need to support the scientific research.Nowadays, the AI technology is a very good example that society should support the scientific research. In the long run, we not only benefit from the progress and facility,but we can harvest from the investment into the AI scientific research.

Not the least,scientific research will help human being to know the unknown things in the society,that deep understanding will contribute ourselves to get better way to get along with the new environment and new world.

The rms speed of the molecules in 1.3 g of hydrogen gas is 1600 m/s.
yulyashka [42]

Answer:

Explanation:

1.3  g = 1.3 / 2 = .65 moles of hydrogen .

.65 moles = 6.02 x 10²³  x .65 molecules

Translational kinetic energy of one molecule = 1/2 mc² where c is rms speed = 1/2 x 2 x 1.67 x 10⁻²⁷ x ( 1600 )² = 42752 x 10⁻²⁵ J

Translational kinetic energy of .65  moles = 6.02 x 10²³  x .65 x 42752 x 10⁻²⁵ J

= 1673 J  approx .

B )  Total thermal energy and total translational kinetic energy are same so

Thermal energy of gas = 1673 J

C )  Net content of thermal energy = 1673 + 500 - 2000 = 173 J  

If c be the rms speed

  1/2 x 2 x 1.67 x 10⁻²⁷ x .65 x  6.02 x 10²³ c² =  173

6.534 x 10⁻⁴ c² = 173

c² = 264769

c = 514.56 m /s

Ede4ka [16]

Answer:

72 m

Explanation:

Given:

v₀ = 0 m/s

v = 60 m/s

a = 25 m/s²

Find: Δx

v² = v₀² + 2aΔx

(60 m/s)² = (0 m/s)² + 2 (25 m/s²) Δx

Δx = 72 m
