Why we can not reach the speed of light |
| Answer» 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. | |

What is Bernoulli\'s therom |
| Answer» 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 or we can say that 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. | |

Sir please explain me rotatry motion |
|
Answer» The type of motion of an object in which it\'s particle moves in circular orbits with same angular velocity but different linear speed is called rotational motion.And the axis along which particle revolve in circular orbits is called axis of rotation. A rotation motion is a motion that takes place around a fixed axis. A worm drive is an example of rotational motion. Both the worm and the worm gear—is rotating on its own axis.Rotatary Motion of a planets on it\'s axis. |

What is surface tention? |
|
Answer» The force acting at 90 degree along 1cm of length Surface Tension: The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface. This forms a surface "film" which makes it more difficult to move an object through the surface than to move it when it is completely submersed. Surface tension is typically measured in dynes/cm. |
