  • uniform velocity

    Q

    Here
    u = initial velocity = 36 km/hr
    v = Final velocity = 0 km/hr
    s = Distance traveled = 10m = 10/1000 km = 0.01 km
    We can use the equation of motion i.e. v2 = u2 + 2as
    (36)^2 + 2 x a x 0.01 = 0
    acceleration  = a = -1296/0.02 = -64800 km/sq hr

    For calculating the time (t), we will use v = u + at
    36 = 0 -64800 x t
    t = -36/64800 = 0.00055 hr = 2 seconds

  • Value of g

    Q

    Acceleration due to gravity on the surface of earth g = GM/r2,

    where r is the radius of the earth, M the mass of the earth and G the universal gravitational constant.

    In the above expression for g, G and M are constant. But r varies due to the shape of the earth. We know that the shape of the earth is not a perfect sphere. It is flattened at the poles and bulged at the equator. So the polar radius is smaller than the equitorial radius. Hence g is slightly more at the poles than at the equator. 

    Thus the value of g on earth is maximum at poles and decreases as we go from poles to the equator and is minimum at the equator. also g decreses as we increase or decrease the distance of a body from the centre of the earth. 
    Also the value of g decreases as we go above the sea level and again decreses deep iside the earth.

  • Monera and Protista

    Q

    Kingdom Monera includes ONLY prokaryotic organisms.
    e.g.Cyanobacteria [Blue Green Algae]

    Kingdom Protista includes unicellular eukaryotic organisms.
    e.g, Amoeba, Paramocium, Plasmodium, Euglena etc.

    These kingdoms were made by Robert Whittaker in 1969.
    Initially the organism were classified in 4 kingdoms only. The 5th kingdom i.e Kingdom Fungi was included later in 1973.

  • matter

    Q

    the type of energy that is in motion,i.e., the energy possessed by a body when it is in motion is called kinetic enegy. It's measured in joules(J).

    A
  • what is kineating energy

    Q

    The energy possessed by an object due to its motion is called kinetic energy.

         KE = ½*mv2

     Where, m = mass of an object
               V = velocity of an object
