Scurvy and rickets are micronutrient deficiency diseases due to a lack of certain vitamins or minerals in the diet. Scurvy is caused by vitamin C deficiency and rickets by vitamin D.

<h3>What are proteins and carbohydrates?</h3>

  • Proteins and carbohydrates are the macronutrient in the body and are sources of energy. Proteins are made of amino acids linked together by the peptide bond and carbohydrates are made of carbon, oxygen, and hydrogen.

  • Breathing is a biological process that involves exhalation and inhalation, while respiration is a chemical process that occurs in body cells and tissues.

  • The cerebrum and cerebellum are the parts of the brain involved with different functions. The cerebrum of the forebrain is involved with mental, motor, and sensory functions, while the cerebellum is involved with posture, balance, and coordination.

  • The infectious disease gets transmitted to another person by viruses, bacteria, fungi, etc., and non-infectious are non-communicable disease that includes age, deficiency, etc.

Answer:

Explanation:

All substances have characteristic physical and chemical properties. Physical properties are those that can be observed with the senses without changing the identity of the substance. Chemical properties describe how a substance can be changed into a new substance. Physical and chemical properties, such as color, density, boiling point, solubility, conductivity, and flammability, A. are always different between substances. B. depend on the amount of the substance. C. do not depend on the amount of the substance. D. have the same values for all substances.

strojnjashka [21]

Answer:

Option d

The minimum angular separation between two objects that the Hubble Space Telescope can resolve is 4.8x10^{-8}rad.  

Explanation:

The resulting image in a telescope that will be gotten from an object is a diffraction pattern instead of a perfect point (point spread function (PSF)).

That diffraction pattern is gotten because the light encounters different obstacles on its path inside the telescope (interacts with the walls and edges of the instrument).

 

The diffraction pattern is composed by a central disk, called Airy disk, and diffraction rings.    

 

The angular resolution is defined as the minimal separation at which two sources can be resolved one for another, or in other words, when the distance between the two diffraction pattern maxima is greater than the radius of the Airy disk.

The angular resolution can be determined in analytical way by means of the Rayleigh criterion.          

\theta = 1.22\frac{\lambda}{D}  (1)

Where \lambda is the wavelength and D is the diameter of the telescope.

Notice that it is necessary to express the wavelength in the same units than the diameter.

\lambda = 95nm \cdot \frac{1x10^{-9}m}{1nm} ⇒ 9.5x10^{-8}m

Finally, equation 1 can be used.

\theta = 1.22(\frac{9.5x10^{-8}m}{2.4m})

\theta = 4.8x10^{-8}rad              

Hence, the minimum angular separation between two objects that the Hubble Space Telescope can resolve is 4.8x10^{-8}rad.
