g = - GM/r^2 so we have:
-G * M / r^2 and -G * 2 * M / (r * 3)^2
Cleaning up the equation since we don’t need the negatives or G since they are constant in both equations:
M / r^2 and 2 * M / (r * 3)^2
We’ll set M to 1 and r to 1 so we get:
1 / 1^2 and 2 * 1(1 * 3)^2
1 and 2 / 3^2 would be equivalent to 1 and 2/9.
Therefore, for every 1 kg on Earth, you would weigh 0.2222 kg on the new planet.
C. Few valuable natural resources
Option A , angle 3 is the correct answer
Answer:
People live close to volcanoes because Geothermal energy can be harnessed by using the steam from underground which has been heated by the Earth's magma.Apart from the volcano itself, hot springs and geysers can also bring in the tourists. This creates many jobs for people in the tourism industry.
