Answer:

Choose the answer that best completes this sentence: The Moon may have contributed to the evolution of life from its gravitational pull.

Explanation:

The gravitational pull between the Earth and the Moon contributed with the evolution of life due to tides.

Remember that tides are formed as a consequence of the differentiation of gravity due to the Moon across to the Earth sphere, that allows the presence of currents in the sea, which avoid the water to stagnate and loss its nutrients for life in it.

However, it is known that life starts in the sea.

The International Space Station has a mass of 1.8 × 105 kg. A 70.0-kg astronaut inside the station pushes off one wall of the st

Aleonysh [2.5K]

Answer:

$a = 5.83 \times 10^{-4} m/s^2$

Explanation:

Since the system is in international space station

so here we can say that net force on the system is zero here

so Force by the astronaut on the space station = Force due to space station on boy

so here we know that

mass of boy = 70 kg

acceleration of boy = $1.50 m/s^2$

now we know that

$F = ma$

$F = 70(1.50) = 105 N$

now for the space station will be same as above force

$F = ma$

$105 = 1.8 \times 10^5 (a)$

$a = \frac{105}{1.8 \times 10^5}$

$a = 5.83 \times 10^{-4} m/s^2$
