Answer:
a one rotation of the planet on its axis
Explanation:
The two types of motion that planets undergo are;
1) rotation of the planet about its axis
2) revolution of the planet around the sun.
In every planet there are days as shown in the image attached to the question. However, the length of day in each planet is determined by the time required for the planet to complete one rotation on its axis.
It takes the earth 1 earth day (24 hours) to complete rotation on its axis.

Answer:</h3>
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
<h3>
Explanation:</h3>
We are required to complete the chemical equation given;
strontium carbonate + sulfuric acid → ??
- We know that, carbonates reacts with acids to form a salt, water and carbon dioxide.
- Strontium carbonate reacts with sulfuric acid to form strontium sulfate, water and carbon dioxide.
- Therefore, the equation for the reaction is;
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
- The equation is balanced as the number of atoms of each element are equal on both sides of the equation.
Answer:
Earth is the only planet in the solar system with large quantities of surface water, and with water comes all the things that dissolve in it, including salt.

Answer:
Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms. All species of animals, land plants and most fungi are multicellular, as are many algae, whereas a few organisms are partially uni- and partially multicellular, like slime molds and social amoebae such as the genus Dictyostelium.

The atomic radius increases as we go down a group/family on a periodic table.
Explanation:
"Atomic radius" is defined as the "one-half of the distance" between the "nuclei of two atoms". While moving down the group in a periodic table there is an "increase in quantum number n" which allows the valence electrons to occupy on higher levels. This shows that the valence electrons move away from the nucleus, which makes them to be loosely held. Thus, atomic radius is large.
Similarly while moving across the periodic table from "left to right" the atomic radius gradually decreases.
