Answer: Rotation cause by the earths orbit and gravity
Explanation:
Answer:

Explanation:
Given
The data in the table
Required
Follow the steps appended to the question;
Step 1: Calculate the Mean or Average
Mean = Summation of lengths divided by number of teams;



Step 2: Get The Range



Step 3: Divide Range by 2



Step 4: Determine the Precision

Substitute 2.70 for Average and 0.1 for Approximate Range

The objects that are rubbed together will create charges among themselves due to friction.
(1) The balloon rubbed with a wool cloth will be charged.
(2) If she comb near a small, uncharged object nothing will change.
(3) This is a scientific investigation because it does not involved a step by step process to answer a scientific query.
Answer:
B. Write the chemical equation using formulas and symbols.
D. Count the atoms in each substance in the reactants and products,
Explanation:
When balancing chemical equation, it implies that the law of conservation of matter be strictly adhered to.
By so doing, the number of atoms on both sides of the reaction must be the same. Number of atoms in the products and reactants must have the same value.
- It is always a good approach to first write the chemical equation of the reaction.
- This will give an overview of the reacting species and the products being formed.
- Then, go on to count the number atoms in the reactants and product sides of the expression.
- Then balance it using any of the method of balancing chemical equations.
Adhesion is responsible for a meniscus and this has to do in part with water's fairly high surface tension. Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus. They'll travel up the glass as far as water's cohesive forces will allow them, until gravity prevents them from going further. Cohesion is an intermolecular attraction between like molecules (other water molecules in this case).
