    Yogita Ingle 4 years, 1 month ago

    A plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons.

    Specifically, plasma is ionized gas. That is gas that has been given an electrical charge by being stripped of electrons. Such ionized gas is the most abundant observable form of matter in the universe, being the main ingredient in stars and nebulas.

    The universal law of gravitation states that every object in the universe attracts each other object with a force which is directly proportional to the product of their masses and indirectly proportional to the square of distance between them.

    To calculate the value of g, we should put the values of G, M and R in Eq. (9), namely, universal gravitational constant,
    G = 6.7 × 10–11 N m2 kg-2, mass of the earth,
    M = 6 × 1024 kg, and radius of the earth,
    R = 6.4 × 106 m.

     g=G M/R2

      6.7 10-11 N m2 kg-2 6 1024 kg / (6.4 106 m)2  = 9.8 m s–2.

    Thus, the value of acceleration due to gravity of the earth, g = 9.8 m s–2.

    Therefore the solution=75+x
    15% (75+x)=75
    75+x=75*100/15
