The first satellite to capture a photograph of Earth from space was Explorer 1, launched on January 31, 1958. This and subsequent space missions like the Apollo program expanded our visual understanding and perception of our planet.
The first satellite to give us a photograph of the Earth from space was Explorer 1, launched on January 31, 1958. Prior to Explorer 1, the Soviet Union had launched Sputnik 1 in October 1957, but Explorer 1 was the first satellite to provide us with images of Earth from space. This marked a significant moment in human history, altering our perception of the planet.
Later on, the Apollo program further improved our visual understanding of Earth, with the Apollo 17 mission capturing the 'Blue Marble' - one of the rare full disk images of the Earth in sunlight. Such images underscored our perception of Earth as a small, yet interconnected and strikingly beautiful, celestial body floating in the vastness of space.

Answer: The velocity of the ball the ball after collision is 5.5 m/s.
Explanation:
John hitting the bottle which is at rest means this is an Elastic collision.
Mass of the ball=
Velocity of ball before collision =
Velocity of ball after collision =
Mass of the bottle=
Velocity of bottle before collision = (bottle is at at rest)
Velocity of bottle after collision =
The velocity of the ball the ball after collision is 5.5 m/s.
