    When oil drop is carefully placed on the surface of water, it weakness/breaks surface tension at that particular point(it act as impurity); the greater surface tension on the other side of the oil drop pulls it leading to formation of oil patch. Oil drop also spread(to oil patch) due to greater adheRead more

Oil drop also spread(to oil patch) due to greater adhesive force between oil and water molecules than cohesive between water molecules

    Initial k.e = ½*20*4*4 = 160j Final k.e = 2*160 = 320j Final Velocity = √(2*320)÷20 = √32 m/s = 5.66m/s Ft = m(v-u) t = 20(√32-4)÷5 t = 6.64s

    Initial k.e = ½*20*4*4
    = 160j

    Final k.e = 2*160
    = 320j

    Final Velocity = √(2*320)÷20
    = √32 m/s
    = 5.66m/s

    Ft = m(v-u)

    t = 20(√32-4)÷5
    t = 6.64s

    From the concept of floating, archimede's idea, any object displaces its own weight in the fluid in which it floats, so the reason is simple in that; a good portion of the interior of the boat is air (unlike a cube of steel, which is solid throughout). The average density of a boat ( the combinationRead more

    From the concept of floating, archimede’s idea, any object displaces its own weight in the fluid in which it floats, so the reason is simple in that; a good portion of the interior of the boat is air (unlike a cube of steel, which is solid throughout). The average density of a boat ( the combination of the steel and the air ) is very light compared to the average density of water while average density of solid steel is greater than average density of water. So very little of the boat actually has to submerge into the water before it has displaced the weight of the boat. Thus the boat floats while a solid steel sinks.
