The escape velocity at the surface of Earth is approximately 11 km/s. What is the mass, in units of ME (the mass of the Earth),

SVETLANKA909090 [29]

Answer:11 km/s

Explanation:

Given

Escape velocity at the surface of earth is 11 km/s

Escape velocity is given by

$V_e=\sqrt{\frac{2GM}{R}}$

Escape velocity at the surface of earth

$11=\sqrt{\frac{2GM}{R}}$ --------------------1

If Escape velocity is three times and the radius is also the three times

$V_e_2=\sqrt{\frac{2G(3M)}{3R}}$

$V_e_2=\sqrt{\frac{2GM}{R}}=V_e$

i.e. $V_e_2=11 km/s$

The air also contained a small amount of argon

AysviL [449]

The argon molecules become solid when the temperature decrease from 20C to -190 C.

<h3>What changes occur in argon?</h3>

The changes in arrangement and movement of the particles of the argon occurs as the temperature of the air decreased because the argon gas begins to freeze. The freezing point of argon is -189 Celsius so when the temperature decrease from 20C to -190 C, the argon molecules becomes solid.

So we can conclude that the argon molecules become solid when the temperature decrease from 20C to -190 C.

Why are SI units helpful for describing objects? A. They are the standard used by scientists worldwide. B. They are more accurat

Ganezh [65]

They are the standard system used by scientists worldwide, and
officially by almost all nations of the world. So if you describe a
measurement in terms of SI units, there's less chance that you'll
need to explain the measurement to anyone who reads it ...
most scientists and common people worldwide will understand
what your number means.
