Asteroid A has a mass of 7.80×1020 kilograms (kg), and asteroid B has a mass of 3.70×1018 kg. Assuming that the same force was a
PtichkaEL [24]

Answer:

The ratio of asteroid-A’s acceleration to asteroid-B’s acceleration is 37:7800.

Explanation:

Mass of asteroid-A = m =7.80\times 10^{20} kg

Mass of asteroid-B = m' = 3.70\times 10^{18} kg

As we know , Force = mass × Acceleration

1) Force on an asteroid-A

F = m\times a

where , a is the acceleration due to force applied on asteroid-A

2) Force on an  asteroid-B

F' = m'\times a'

where , a' is the acceleration due to the force applied on asteroid-B

Same force is exerted on the both the asteroids say F.

F = F'

m\times a=m'\times a'

\frac{a}{a'}=\frac{3.70\times 10^{18} kg}{7.80\times 10^{20} kg}=\frac{37}{7800}

The ratio of asteroid-A’s acceleration to asteroid-B’s acceleration is 37:7800.

This is because this approach has a holistic behavior, so it is able to optimize all the digital, administrative, organizational and technical components of a company, together with all sectors, taking into account all aspects of the company. Therefore, any analysis shows highly complete results, and can provide a good view of what the institution intends to do and what is being done so that all objectives are achieved.
