Native Americans, otherwise called American Indians, Indigenous Americans and different terms, are the indigenous people groups of the United States, aside from Hawaii. There are more than 500 governmentally perceived clans inside the US, about portion of which are related with Indian reservations.

The overarching hypothesis recommends that individuals moved from Eurasia crosswise over Beringia, a land connect that associated Siberia to introduce day Alaska amid the Ice Age, and afterward spread southward all through the Americas over the resulting ages

Gas cloud 1is likely to form a star . Gas cloud 2 is not . Based on this information, match the given conditions with each cloud

kondaur [170]

Answer:

1. It spreads with a greater volume and less concentration of elements.
Its temperature stays well below the 14 million Kelvin.
It has hydrogen atoms that retain there electrons.
2. Its volume shrinks and the density increase die to the gravity
Its temperature stays above the 14 million kelvin
Hydrogen atoms shed there electron.

Explanation:

As the star is born within the clouds of dust and is scattered throughout most galaxies. The Orion Nebula is shown in the image that has a turbulence layer of clouds made of gases. These clouds tend to have temperatures of 100 Kelvin thus commonly called the HI clouds.

3. A space vehicle is traveling at 4300 km/h relative to Earth when the exhausted rocket motor (mass 4m) is disengaged and sent

kvv77 [185]

Answer: Vce= 4234.4km/hr or 1180m/s

Explanation:

Mass of rocket motor Mr= 4m

Mass of control module Mc= m

Initial velocity of spaceship relative to earth Vs= 4300km/hr

Final velocity of command module relative to the rocket motor Vrc = 82km/hr

Total mass of spaceship M= 4m+m= 5m

Using law of conservation of momentum;

MVs= MrVre + McVce eqn1

Vre = Vrc+Vce eqn2

Where Vce is velocity of control room relative to the earth and Vre is velocity of rocket motor relative to the earth

Substituting eqn2 to eqn1, we have.

MVs= Mr(Vrc+Vce) +McVce

MVs= MrVrc+MrVce+McVce

Making Vce the subject of formula.

Vce = (MVs-MrVrc)/(Mc+Mr)

Substituting the values we have,

Vce = (5m×4300km/hr - 4m×82km/hr)/ (m+4m)

Vce = 21172m/5m

Vce= 4234.4km/hr or 1180m/s
