area is the space bounded by certain lines, the SI unit of area is m²
area of rectangle =l×w×h
square=l²
The total number of orbitals in the n = 1 through 4 shells is only 1.
The relationship between the n value and the total number of orbitals is given as
Total number of orbitals = n²
Because there is only one way a sphere can be orientated in space, there is only one(1) orbital in the n = 1 shell.
An orbital has n² total orbitals for a given value of n.
Each atom's electron is given one of four quantum numbers, the primary quantum number (symbolized n), to describe the state of that electron. It is a discrete variable since the values are all natural numbers starting at 1.
The orbital's size is defined by the primary quantum number (n). For example, orbitals with n = 2 are larger than those with n = 1.
Electrons are drawn to the atom's nucleus because their electrical charges are in opposition to one another.
In order to excite an electron from an orbital where it is close to the nucleus (n = 1) to an orbital where it is distant from the nucleus (n = 2), energy must be absorbed.
Thus, the energy of an orbital is indirectly described by the primary quantum number.

Answer:
The time taken by the car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s is 0.84 seconds.
Explanation:
Given that,
Acceleration of the car, 
Initial speed of the car, u = 24.6 m/s
Final speed of the car, v = 26.8 m/s
We need to find the time taken by the car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s. The acceleration of an object is given by :
t = 0.84 seconds
So, the time taken by the car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s is 0.84 seconds. Hence, this is the required solution.
Answer:
A. Water would be a gas at room temperature, and
D. Ice would sink in water.
Explanation:
There are three types of intermolecular forces: London dispersion forces, dipole-dipole interactions, and hydrogen bonds. The relative strength of these forces depend on the size of the molecule. However, for small molecules like water (three atoms per molecule,) hydrogen bonds would be much stronger than the other two types of forces.
Without hydrogen bonds, water molecules would be held together only with dipole-dipole interactions and London dispersion forces. To get an idea of what that would be like, consider hydrochloric acid 
.
and water 
contain about the same number of electrons. The H-Cl bond in is polar, which allows for dipole-dipole interactions. However, only H-O, H-F, and H-N bonds allow for hydrogen bonding. As a result, there won't be any hydrogen bonding between molecules. Without hydrogen bonding, boils at well below 
under standard pressure. It is a gas at room temperature under standard pressure. That's about the same as what water molecules would behave (physically) without any hydrogen bonds between them.
Also because of hydrogen bonding, the density of ice (solid ) is typically greater than that of water (liquid .) When compared to water in its liquid state, there are more hydrogen bondings between molecules of water in its solid state. The hydrogen bonds hold the molecules together to form a lattice. Because of this structure due to hydrogen bondings, the molecules are farther apart than they are in the liquid states. As a result, the density of ice is typically smaller than that of water. That would likely not be the case if there was no hydrogen bondings between water molecules.
