consider the mass of the earth and the mass of the sun. then consider the distance between the astronaut and the sun.
you will see that the force of the Earth's gravity is much greater due to the formula above as the very large distance from the sun
To find area you multiply its height by the width so 2x2 = 4 (what unit it is)
Answer: Debate and discussions on climate change are very important among scientists.
Explanation: Many scientific opinions have expressed in the form synthesis reports, by scientific bodies both national and international standing, and also by debate and surveys of opinion among climate scientists. The aim is to mitigate against climate change and creating awareness of the adverse effect on our enivornment.
