Suppose the earth suddenly came to halt and ceased revolving around the sun. The gravitational force would then pull it directly
to the sun. What would be the earth's speed as it crashed?
1 answer:
Answer:
613373.65233 m/s
Explanation:
M = Mass of Sun = 
m = Mass of Earth
v = Velocity of Earth
r = Distance between Earth and Sun = 
= Radius of Earth = 
= Radius of Sun = 
In this system it is assumed that the potential and kinetic energies are conserved

The velocity of Earth would be 613373.65233 m/s

The answer is 22.1925 I hope you get right let me know I got my answer because I multiply it all together.
The worm is the invertebrate. All the other animals are vertebrates.
X-component of a projectile in flight =
(initial x-component)
plus
(initial horizontal component of velocity) x (flight time so far)
C. Because they are in the same group, so they have the same number of valence (outer) electrons
