    Yes if two identical ball collide to each other in frictionless surface among ehich one is in rest and other one is moving with velocity v collisions takes place after collisions their state changes among them selves (body which was at rest start moving with velocity v and ball which was moving comes to rest.

    With increase in speed of liquid decrease in pressure of liquid

    0Thank You

    Amar Kumar 8 years, 4 months ago

    Bernoulli’s theorem states that whenever there is an increase in the speed of the liquid, there is a simultaneous decrease in the potential energy of the fluid .There is a decrease in the pressure of the fluid.

    Basically, it is a principle of conservation of energy in the case of ideal fluids. If the fluid flows horizontally such that there is no change in the gravitational potential energy of the fluid then increase in velocity of the fluid results in a decrease in pressure of the fluid and vice versa.

    The shape of water drop is spherical because water drop always tend to acquire minimum surface area due to to surface tension where the droplets of water are pulled into a spherical shape by the cohesive forces of the surface layer.

    As objects travel faster and faster, they get heavier and heavier , the heavier they get, the harder it is to achieve acceleration, so you never get to the speed of light. A photon actually has no mass .If it had mass, it couldn't travel at the speed of light.

    Particles that have mass require energy to accelerate them. The closer to the speed of light you get a particle, the more energy is required to go faster. This is because the particles themselves get more massive in proportion to the increased velocity.
