Buoyant force depends upon volume and density, since, saturated salt solution have higher density than the water. While two students will indeed exert gravitational forces upon each other, these forces are too small to be noticeable. D. Molecular mass only. It is denoted by R and expressed as energy per temperature increase per mole. When the volume of a sample of gas is doubled and the Kelvin temperature is cut in half, the pressure of a sample remains constant. Join the 2 Crores+ Student community now! Answered by | … A constant does not depend on anything, its a value. Its not a characteristic of a particular phenomena or define any process. Its simply a value which is fixed anywhere and anypart of the universe. Just as mass of a body is fixed, be it on the earth or be it in the moon or be it in some other galaxy. Question 5. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation. velocity of a gas depends upon. Universal Gravitation for Spherically Symmetric Bodies. It describes the strength of the gravitational forces that a massive object exerts at any location around it.

In the Sackur–Tetrode theory the constant depends only upon the mass of the gas particle. Watch Video in App. Maharashtra State Board HSC Science (General) 12th Board Exam. The Law of Universal Gravitation states that the gravitational force between two points of mass is proportional to the magnitudes of their masses and the inverse-square of their separation, [latex]\text{d}[/latex]: [latex]\displaystyle \text{F}=\frac{\text{GmM}}{\text{d}^2}[/latex] However, most objects are not point particles. The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. The ideal gas law has many implications that will be discussed below. The story of the gravitational constant, Big G: In 1686 Isaac Newton realized that the motion of the planets and the moon as well as that of a falling apple could be explained by his Law of Universal Gravitation, which states that any two objects attract each other with a force equal to the product of their masses divided by the square of their separation times a constant of proportionality.
