    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

    A simple pendulum consists of a small metal ball (called bob) suspended by a long thread from a rigid support, such that the bob is free to swing back and forth.

    3Thank You

    Yogita Ingle 7 years, 2 months ago

    A simple pendulum is defined as an object that has a small mass (pendulum bob), which is suspended from a wire or string having negligible mass.  

    • Whenthe pendulum bob is displaced it oscillates on a plane about the vertical line through the support.
    • Simple pendulum can be set into oscillatory motion by pulling it to one side of equilibrium position and then releasing it.

    Atmospheric pressure is expressed in quite a number of units. 1) Atmosphere (atm) : Naturally the easiest. Ambient pressure = 1 atm. 2) Bar : Popular, yet non-SI unit. 1 atm = 1.01325 bar (source: google!) 3) Pascal : The SI unit of pressure, but not very popular in Earth sciences. 1 atm = 101.325 KPa (no wonder it’s unpopular) 4) Torr : Manometric unit of pressure (mm column of Hg). Quite old. Almost no significance today. 1 atm = 760 Torr 5) psi (pounds-per-square-inch): Also informal. Prevalent form of pressure measurement. However, not very popular in Earth sciences or meteorology. 1 atm = 14.6959 psi.

    1Thank You

    Yogita Ingle 7 years, 2 months ago

    Atmosphere is a mixture of different gases. All these gas molecules together constitute some weight. By virtue of this weight there is some pressure exerted by the atmosphere on all the objects. This pressure is known as atmospheric pressure.

    Units of Pressure:-

    1.SI unit: Pascal (Pa)

    • Pressure is always measured by taking sea level as the reference level. At sea level P=1.01*105 Pa.
    1. Atmosphere (atm)
      • Reference level is at sea level.
      • Pressure equivalent of 76cm of Hg column
      • 1atm=76cm of Hg column
      • 1atm=1.01*105 Pa

    A perfectly rigid body means no matter how much load you apply it is neither going to deform nor any shape change. The high school kinematics and dynamics we study inherently assumes that body is perfectly rigid and no amount of force is going to change its shape.
