The heart was the most important organ to the Egyptians.
Explanation:
When the Egyptians mummified their leaders, they did this to prepare then for the afterlife. Because of this, personal items and other objects of value are found in the tombs. In the case of the heart, the Egyptians considered it to the organ that the deceased would need in the afterlife. Rather than associating intelligence with the brain, the ancient Egyptians believed that the control center of the human body was the heart.
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.
Answer:
A. Reforestation makes the forest renewable, so the company has a stable supply of timber.
Explanation:
If a company uses timber in order to produce paper, it can go either way for the environment, but also for the business itself.
If the company is not reforesting, than it will constantly cut down new trees, with much higher rate than what they can reforest the cut down area, so eventually there will be no trees, so the environment will be destroyed, and the business will be left without its basic material.
If the company uses the method of reforestation though it is a different story. If for every tree that is cut, there is another one that is planted on its place, the forest will constantly be in good shape. Also, the timber in this manner will be a renewable resource, as its replenishing will be at roughly the same rate as the cutting down of the trees. The environment will stay in good condition, and the business will constantly have its basic material in order to operate.
