The statements which describe the principles of the big bang theory include:
Big bang theory was postulated by Georges Lemaître and he is regarded as
the father of this principle. This principle talks about how the universe was
formed.
He proposed that the universe was formed from a single point which then
began expanding and stretching to accommodate more components.

Answer:
doppler effect
Explanation:
When the relative motion of two bodies results in the wavelength becoming shorter this means that the bodies are getting closer. This is known as blue shift.
When the relative motion of two bodies results in the wavelength becoming longer this means that the bodies are getting farther. This is known as red shift.
Collectively this phenomenon is known as the Doppler effect.
Sound can be best described as a mechanical wave and a disturbance in matter that is transmitted from its source outward. This disturbance can move in the form of periodic waves or longitudinal waves. The speed, frequency, and wavelength of a sound are interconnected and sound requires a medium to propagate.
Sound is best described as a mechanical wave, a type of disturbance in matter that is transmitted from its source outward. This movement can be in the form of periodic or longitudinal waves, implying that they move matter back and forth in the direction of the wave's motion. The speed of sound, its frequency, and its wavelength are interconnected, and this is described mathematically by the relationship v = fλ. This relationship shows that the velocity of sound (v) equates to the frequency (f) multiplied by the wavelength (λ).
Sound waves can be both audible and inaudible, originating from various sources, ranging from musical instruments to vocal voices to explosive bangs like a sonic boom. Also, to note is that sound is interpreted through our sense of hearing, and different frequencies and intensities create different sounds. Sound also has the ability to travel through different mediums, including solids, liquids, and gases, with varying speeds.
On a microscopic level, sound can be seen as synchronized oscillation of atoms. This type of motion is more organized than the thermal motion of the atoms. The behavior of sound waves is significantly different from light waves, as sound requires a medium to propagate, while light can travel in a vacuum.

Answer:
Water is non-polar molecule False
Water is polar molecule because the electronegativity of Oxygen is much greater than electronegativity of hydrogen and it has also a bend shape that is why it is polar molecule.
Explanation:
I hope this will help you :)
False. Water is a polar molecule.
Water (H2O) consists of two hydrogen atoms and one oxygen atom. The oxygen atom has a higher electronegativity, meaning it attracts electrons more strongly than hydrogen.
As a result, the shared electrons in the covalent bonds between hydrogen and oxygen are pulled closer to the oxygen atom, creating an uneven distribution of charge.
This leads to a partial negative charge (δ-) on the oxygen atom and partial positive charges (δ+) on the hydrogen atoms, making water a polar molecule.
