Kepler’s 3rd Law of Periods: This law is known as the law of Periods. The square of the time period of the planet is directly proportional to the cube of the semimajor axis of its orbit. T² ∝ a³ That means the time ‘ t ‘ is directly proportional to the cube of the major axis. Let us derive the equation of Kepler’s 3rd law. Let us suppose, m = mass of the planet M = mass of the Sun v = velocity in the orbit So, there has to be a force of gravitation between the Sun and the planet. F = GmMr² Since it is moving in an elliptical orbit, there has to be a centripetal force. Fc = mv²r² Now, F = Fc ⇒ GMr = v² Also, v = circumferencetime = 2πrt Combining the above equations, we get ⇒ GMr = 4π²r²T² T² = 4π2r3)GM ⇒ T² ∝ r³

naaa,,, The more the amount of solute, the more negative is the value solute potential. So the solute potential of a solution is always negative due to the increase in the solute concentration in a solution.

Yakshi ? 6 years, 11 months ago

I think more no. Of solute molecules increases the solute potential....???

Yakshi ? 6 years, 11 months ago

Ohh thanks now i got it......?
Solute potential is always negative as more the solute molecules in the solution lesser the solute potential.

Resonance structures have two or more possible electron structures. Often, they are showed with dotted lines or two+ structures with an arrow between them. The electrons distribute themselves evenly between both configurations (probability-wise) so that what we end up is roughly an "average".

3. Larynx: It is a chamber situated in the region of neck. It is supported by four cartilages : thyroid is the largest and in the form of a broad ring incomplete dorsally, cricoid is a complete ring lying at the base of thyroid, a pair of arytenoids lying above the thyroid but in front of cricoid, and epiglottis situated behind the tongue that serves to cover the entrance to the trachea so that food particles may not enter into it. Larynx is also known as voice box since it helps in the production of sound. 4. Trachea: It is a tube starting from larynx running through the neck and the thoracic cavity. The trachea runs through the neck in front of the oesophagus. The trachea or windpipe is about 12 cm long and divided into two bronchi in the thoracic region. 5. Bronchi and bronchioles: The two bronchi enter into right and left lungs of either side. Inside the lungs they further branch into many smaller bronchioles with a diameter of about 1 mm. These bronchioles further divide into terminal and then into respiratory bronchioles. Each respiratory bronchiole divides into a number of alveolar ducts that further divide into atria, which swell up into air sacs or alveoli. 6. Lungs: A pair of conical shaped lungs is situated in the double walled sacs called pleural cavities. They are spongy and richly supplied with blood vessels and capillaries. They have about 300-400 millions of alveoli through which exchange of gases occur. Lungs have various bronchioles ending into alveoli where exchange of gases occurs. The alveoli are thin walled pouches the walls of which have epithelial linings supported by basement membrane. I hope my answers help U ☺☺☺☺

All mammals have lungs for the purpose of respiration. This is known as pulmonary respiration. The mammalian respiratory system consists of the nasal cavity, nasopharynx, larynx, trachea, bronchi, bronchioles and lungs. 1. Nasal cavity: It is a large cavity lying dorsal to the mouth and is lined by mucous secreting epithelium. The nasal cavity opens outside through a pair of external nostrils or nares. Bones and cartilages support the nasal cavity. The nasal cavity is divided into two parts by a nasal septum. The cavity opens inside into pharynx through two internal nostrils. Air while passing through the nasal cavity is filtered, and only the clean air free from dust particles and foreign substances enters the pharynx. The air also gets warmed and moistened in this chamber. It is important to note that air can also be inhaled through mouth directly, but this is not advisable because the air will not be filtered, warmed and moistened. This gradually will harm the respiratory system. 2. Nasopharynx: It is a chamber situated behind the nasal cavity. At the level of soft palate, it becomes continuous with the mouth cavity or oral pharynx. It also receives the openings of eustachian tubes on its lateral sides and is thus connected to the middle ear.
