An object with a height of 0.3 meter is placed at a distance of 0.4 meter from a concave spherical mirror. An image with a heigh
Sophie [7]

We can use the magnification equation for this problem.

Magnification equation:

<em>hi/h0 = di/d0</em>

Where in <em>hi </em>: image size, <em>h0</em> : object size, <em>di </em>: image distance, <em>d0 </em>: object distance from mirror

So plugging in the given variables we will have the corresponding equation

0.1 m / 0.3 m = <em>di / </em>0.4 m

<em>di</em> = 0.1333333m

The generated image of the object is located 0.13 meters or 13 cm away from the mirror

4. describe three ways carbon dioxide was removed from the Earth's atmosphere.

Answer: Forests: Photosynthisis helps clear carbon dioxide naturally, Soils naturally store carbon, but agricultural soils are running a big deficit due to intensive use. Because agricultural land is so expansive, Bio-energy with Carbon Capture and Storage (BECCS) is another way to use photosynthesis to combat climate change. However, it is far more complicated than planting trees or managing soils — and it doesn’t always work for the climate.

5. Explain why there is now 21% Oxygen in the Earth's atomosphere compaired to little or no Oxygen in the Earth's atmosphere 4.5 billion years ago.

Answer: cientists believe that the Earth was formed about 4.5 billion years ago. Its early atmosphere was probably formed from the gases given out by volcanoes. It is believed that there was intense volcanic activity for the first billion years of the Earth's existence.The early atmosphere was probably mostly carbon dioxide, with little or no oxygen. There were smaller proportions of water vapour, ammonia and methane. As the Earth cooled down, most of the water vapour condensed and formed the oceans.

  • Fossils are the preserved remains of organisms that lived several years ago.
  • Fossils are usually found in sedimentary rocks and thick layers of ice in temperate and polar regions.
  • Body fossils are the remains of the body parts of an organism that has been preserved. They can be skeletal parts, teeth, eggs e.t.c
