Answer:
A) First we need to decompose the vector A in x-axis and y-axis:
And also we have for vector B:
To find A + B:
B)
Answer:
E=-1.51 eV.
Explanation:
The nth level energy of a hydrogen atom is defined by the formula,
Given in the question, the hydrogen atom is in the 3p state.
Then energy of n=3 state is,
Therefore, energy of the hydrogen atom in the 3p state is -1.51 eV.
Now, the value of L can be calculated as,
For 3p state, l=1
Therefore, the value of L of a hydrogen atom in 3p state is .

Answer:
Compound.
Explanation:
A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.
Answer:
distance between the charges is 5.12 × 10⁶ m
Explanation:
charges q₁ = -130.0 C
q₂ = 180 C
force between the charges = 8 N
force between two charge
value of K =8.975 × 10⁹ N.m²/C²
r = 5.12 × 10⁶ m
hence, distance between the charges is 5.12 × 10⁶ m.
