What is the escape velocity on the Venus ? Venus' mass 4.90*10^ 24 kg and radius is 6.86 * 10 ^ 6 * m
gtnhenbr [62]

The escape velocity on Venus is 9761 m/s

Explanation:

The escape velocity from a planet is the speed that an object on the surface of that planet must have in order to completely escape the gravitational field of the planet.

Mathematically, it is calculated as

v=\sqrt{\frac{2GM}{R}}

where

G is the gravitational constant

M is the mass of the planet

R is the radius of the planet

For Venus, we have:

M=4.90\cdot 10^{24}kg is the mass

R=6.86\cdot 10^6 m is the radius

Substituting, we find the escape velocity on Venus:

v=\sqrt{\frac{2(6.67\cdot 10^{-11})(4.90\cdot 10^{24})}{6.86\cdot 10^6}}=9761 m/s

BRAINLYIST ASAPPP write and claim evidence and reasoning statement that explains why mercury and Venus do not have any moons
umka2103 [35]

answer:They are too close to the sun!

Explanation:Because Mercury is so close to the Sun and its gravity, it wouldn't be able to hold on to its own moon. Any moon would most likely crash into Mercury or maybe go into orbit around the Sun and eventually get pulled into it.Same with Venus!
