finlep [7]4 years ago

Well, the unit of measurement would be the Hertz (after Heinrich H) Hz. But, that doesn't by itself, cover the harmonic content of pitch. Does middle C on a piano sound the same as it does on a trumpet or a violin ? Answer is prob not. Reason is that apart from C (about 256Hz) there are harmonics. The harmonics are also in Hz, and spectrum analysis is one way of seeing the "signatures" of different sound sources of the same "pitch" but different sources. Tuning forks sort of work sort of similarly sort of ...

Are the units of the formula ma = mv2/2 dimensionally consistent? Select the single best answer.
Vesnalui [34]

To solve the problem we will simply perform equivalence between both expressions. We will proceed to place your units and develop your internal operations in case there is any. From there we will compare and look at its consistency

ma = \text{Mass}\times \text{Acceleration}

ma = kg \cdot \frac{m}{s^2}

At the same time we have that

\frac{1}{2}mv^2 = \text{Mass}\times \text{Velocity}^2

\frac{1}{2}mv^2 = kg ( \frac{m}{s})^2

\frac{1}{2}mv^2 = kg \cdot \frac{m^2}{s^2}

Therefore there is not have same units and both are not consistent and the correct answer is B.

Humans can see several thousand shades of color but have cone photoreceptors that are sensitive to only three (perhaps four) wav
kipiarov [429]

Answer:

B. Color perception is achieved by activation of various combinations between the tree cone types.

Explanation:

Human eye have only three photo receptor ( three wavelength) but they can see several thousands of shades of color because color perception is gained by combination of these three wave length cone types ( RED, BLUE AND GREEN) into various combinations. Our retina have two types of cell:- cone cells and cylindrical cells. Cone cells are responsible for the identification of color.
