Answer: Option [A]The speed of rotation of the earth is the highest along the Equator. As every part of earth takes a frill round with in 24 hours, the equator being the largest circle of latitude 0o, the speed is greater at the equator due to crossing the maximum distance per hour then at the Arctic circle.
Answer: Option [C]The correct answer is Venus. Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days. Its day lasts longer than its orbit. It orbits the Sun every 224.65 Earth days, so a day is nearly 20 Earth days longer than its year.
Answer: Option [A]Comets revolve around Sun. Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion. Like all orbiting bodies, comets follow Kepler's Laws - the closer they are to the Sun, the faster they move.
Answer: Option [B]The hottest planet is Venus. Venus is the hottest planet in the solar system, the second planet from the sun. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.
Answer: Option [B]The correct answer is Jupiter and Saturn. In order of their distance from the sun. They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
