The definition of theory says that a it is a hypothesis or group hypotheses. In your own words, explain why a theory is also a h

A hypothesis is a tentative and testable explanation, based on observation(s). A hypothesis can be supported or refuted through experimentation or more observation. A hypothesis can be disproven, but not proven to be true.

Answer:

A scientific theory is the in-depth explanation of a natural phenomenon occurring in nature. A theory is formed after the scientific method is followed which supports the theory. A good scientific theory is formed after a number of ideas are linked, tested and proved which are not just guesses.

Since a scientific theory is a well-substantiated and deeply explained idea which overcomes the limited explanation of a proposed hypothesis and unity of many ideas, hence, a theory can be also be known as a well-explained hypothesis.

A good example of scientific theory repeated many times is the "theory of relativity" proposed by Albert Einstein in 1915 which was tested and repeated in 1919 at the time of solar eclipse which was later repeated again by many scientists.

Y_Kistochka [10]

Answer:

See Explanation

Explanation:

a) We know that;

v = λf

Where;

λ = wavelength of the wave

f = frequency of the wave

v = velocity of the wave

So;

T = 2 * 2.10 s = 4.2 s

Hence f = 1/4.2 s

f = 0.24 Hz

The wavelength =  6.5 m

Hence;

v = 6.5 m * 0.24 Hz

v = 1.56 m/s

b)The amplitude of the wave is;

A =  0.600 m/2 = 0.300 m

c) Since the wave speed does not depend on the amplitude of the wave then the answer in (a) above remains the same

Where d = 0.30 m

A = 0.30 m/2 = 0.15 m

Bingel [31]

Answer:

Option 5.

Explanation:

Many of the properties of water like high specific heat, cohesion, high vaporization heat, etc can be contributed to the polar nature of water molecule.

Water being a polar molecule as it contains positively charged hydrogen and an electro-negative oxygen which results in uneven or non uniformity in sharing of electrons which leads to dipole formation and hence polarization of the molecule due to which it attracts its neighboring molecules.

This polar nature imparts the properties like cohesion, surface tension , adhesion, etc due to the presence of hydrogen bonds in water molecule.
