A warmer climate is produced because of the gulf stream which begins at the tip of Florida and flows up all the way to NW Europe.
What is Pluto is changing exactly <span />
It's the only star in the sky (visible from the northern hemisphere) that never seems to move. It stays at almost exactly the same point in the sky, while the other stars all circle around it once a day.
When the planet is closest to the Sun, speed v and kinetic energy are the highest, and gravitational potential energy is the lowest. When the planet moves farther away, the speed and kinetic energy decrease, and the gravitational potential energy increases.
Answer:
v / √5
Explanation:
Centripetal acceleration = acceleration due to gravity
v² / r = GM / r²
v² = GM / r
If the radius is increased to 5r:
u² = GM / (5r)
u² = v² / 5
u = v / √5
