I think the two simple machines that make up a pair of hedge trimmers would be a lever and a spring.
Answer:
the atomic number is 52
Explanation:
atomic number = no of electrons present
Increases
Stays the same
s-orbitals
d-orbitals
p-orbitals
Explanation:
The trend in the electronic configuration on the periodic table follows a definite pattern because the arrangement of elements on the table is based on the periodic law.
The periodic law states that "The properties of elements are a function of their atomic number".
- Elements in the same horizontal period have increasing number of valence electrons.
- The number of valence electrons stays the same down a group.
- Groups 1 and 2 are known as the s-block and electrons are added to the s-orbitals for them.
- Groups 3 to 12 is the transition block and electrons the valence d-orbital.
- Groups 3 through 18 is the p-block where the valence shell is the p-orbital.

Use the formula for volume. V = lwh. Plug in the numbers for length,
width, and height. Now we have V = 4.0 x 2.0 x 1.0, which is 8.0. So the
volume of the block is 8.0 cm.
