B: scientists assume an animal was a meat eater because of the teeth in its fossil C: scientists assume an animal could climb trees because of its hand structure D:scientists predict a volcano will erupt in the near future because of current volcanic activity
A. 5
B. 3
C. 7
D. 4
Answer:
Option B
3
Explanation:
The two dimensions have the following significant numbers
4.56- 3 significant numbers
5.668- 4 significant figures
When responding, we give area as per the most precise number given hence the smallest (most precise) significant figures in these two numbers is 3. Therefore, the area will be given to 3 significant figures ie
4.56*5.668=25.84608 square meters
Area=25.8 square meters
A refracting telescope is a type of optical telescope that uses a lens as its objective to form an image.
Astronomers use a telescope to observe distant things. Curved mirrors are used by the majority of telescopes, including all large telescopes, to collect and concentrate light from the night sky.
Refracting telescopes have been used for centuries and are still commonly used today, especially for viewing bright objects such as the Moon and planets.
However, they have some limitations compared to other types of telescopes, such as difficulty in making large lenses without distortion and the tendency to produce chromatic aberration, which can cause images to appear blurred or discolored.
Despite these limitations, refracting telescopes remain popular among amateur astronomers and are still used in many scientific applications.
