Answer:
1) henry moseley established a periodic table that arranges the elements by atomic number.
2) the atomic number increases from left to right on the periodic table.
3) metalloids have the characteristics of both metals and nonmetals.
Henry Gwyn Jeffreys Moseley (1887–1915) proposed that the number of positive nuclear charges (protons) in atom is equal to its atomic number in the periodic table.
Metalloids create a "staircase" down the periodic table.
For example, germanium (symbol: Ge) is a lustrous, hard, grayish-white metalloid in the carbon group.
Explanation:
An action-reaction pair shows the direct relationship two objects have <u>directly</u> on each other. Therefore, the correct answer is C. The Moons gravity pulls on you, and your gravity pulls on the Moon because it is moon gravity-person person gravity-moon.
Choice A would be made correct if it was you pull on a drawer and the drawer pushes on you OR the table pushes on the ground and the ground pushes on the table.
Choice B would be made correct if it was a computer sits on a table and the table pushes up on the computer.
Choice D would be made correct if it was an eraser sits on a shelf and the shelf pushes up on the eraser OR the wall pushes on the shelf and the shelf pushes against the wall.
Hope this helps!!
Explanation:
The total energy of the system remains conserved. It just converts from one form of energy to another.
The battery of the cell phone contains chemicals. As the electricity is passed through the cell phone, the electrical energy is converted to chemical energy. As she notices that the phone is warm and after the battery has been fully charged and the student unplugs her cell phone, the phone vibrates when a message arrives, this shows the conversion of chemical energy to mechanical energy, thermal energy etc.
Hence, we can say that the correct option is (b).
