    1. Most of the alpha particles passed through the gold foil without getting deflected.
    2. Very few particles were deflected from their path by 180o indicating that the whole mass of the atom is present in its centre in a very small volume.
    3. Few particles were deflected at small angles from their path and very few were deflected from their path by 180o indicating that the positive charge of the atom occupies very little space and is located at the centre.

    The cells that you observed in the above activity are the basic building units of the onion bulb. The cells of onion peel are linear or rectangular in shape. All the cells are firmly bound together. Like onion, all organisms are made up of cells. Some organisms are made up of one cell while others are made up of many cells.

    Chandru M.Chandru 5 years, 5 months ago

    The atom, as described by Ernest Rutherford, has a tiny, massive core called the nucleus. The nucleus has a positive charge. Electrons are particles with a negative charge. Electrons orbit the nucleus. The empty space between the nucleus and the electrons takes up most of the volume of the atom

    Potential energy is the work done to take a body to a certain height. For a body with mass m, h is the distance to which it is raised and g is the gravitational force acting on the body, then work done W is given as:

    W = force * displacement

    W = mg * h

    ∴ W = mgh

    As the work done is equal to mgh which is gained by the object, potential energy Ep is given as:

    Ep = mgh

    Shorter the orbit of the planet around the sun, shorter the time taken to complete one revolution. According to Kepler’s law of periods, the square of the time period of revolution (of a planet around the sun in an elliptical orbit is directly proportional to the cube of its semi-major axis).

    Law of conservation of momentum states that

    For two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed

    Sometimes we see water droplets on the outer surface of the glass containing ice-cold water this is because the water vapour presents in air, on coming in contact with the cold glass of water, loses energy and gets converted to liquid state, which we see as water droplets.
