the earth revolves around the sun...that's how we have night and day
No.
NO. The gravity of Earth, in conjunction with the inertia of the satellite, keeps the satellite revolving around Earth. However, the satellite doesn't get any nearer to the Earth. So, according to the laws of physics, no work is done. (I'm ignoring the fact that satellites sometimes lose height and need to be "boosted" a bit to maintain their orbits. Also, I'm assuming that the satellite's orbit is circular. If the orbit is elliptical the answer is more or less the same, but a bit more complicated.)
Absolutely correct answer= "the four seasons"
The work done on a satellite in a circular orbit around Earth is zero because the gravitational force acting on the satellite is perpendicular to the direction of motion, so no work is done to maintain the orbit.
No because it stays in orbit and takes pictures of the ever changing earth.
Answer #1:YES======================Answer #2:No
The man who proposed the heliocentric model of the universe, with the Earth revolving around the Sun, was Nicolaus Copernicus, a Polish mathematician and astronomer. His work laid the foundation for modern astronomy.
The work done by the Earth on the space station is zero since the force of gravity is perpendicular to the motion of the space station. This means that there is no displacement in the direction of the force, and thus no work is done.
Revolving
Stephen Hawking was a proponent of the heliocentric model, which places the Sun at the center of the solar system with Earth and other planets orbiting around it. Geocentric model, on the other hand, places Earth at the center, with everything else revolving around it. Hawking's work and contributions to science were based on the heliocentric model.
the term "revolving door" in politics means "leaving government to work for an interest group". :DD
