difference between gravity and acceleration due to gravity |
|
Answer» No gravity is a force of attraction but acc due to gravity is acceleration caused by force of gravity There is no net difference Only one difference is that this cant be negative and direction is towards earth core on the other hand simple acc can be in any direction |

| 7516. |
earth is continously pulling moon towards its center . why does not moon fall on the eartg |
|
Answer» As moon exerts two types of forces, centrifugal force and centripetal force just like electrons revolve around nucleus of an atom...and also according to newton\'s third law every action has equal and opposite reaction to counter.. Therefore moon does not fall on the earth. Because Earth has greater attracting capacity than moon. |

What Is modulus of rigidity? Explain |
| Answer» Modulus is a constant of elasticity given by Hooke\'s Law, which says stress is directly proportional to strain, within the elastic limit.Modulus of rigidity is one among three elastic constants. It\'s associated with change in shape of the body.Like every modulus it\'s too equivalent to the ratio of stress and strain. But as per definition, since it\'s the modulus of change in shape, therefore, it\'s precisely expressed by the ratio of shearing stress and shearing strain.We know shearing stress is F÷A and shearing strain is theta ( I would like to consider it β) | |

| 7522. |
Kepler\'s laws |
| Answer» Kepler\'s LawsJohannes Kepler, working with data painstakingly collected by Tycho Brahe without the aid of a telescope, developed three laws which described the motion of the planets across the sky.1. The Law of Orbits: All planets move in elliptical orbits, with the sun at one focus.2. The Law of Areas: A line that connects a planet to the sun sweeps out equal areas in equal times.3. The Law of Periods: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.Kepler\'s laws were derived for orbits around the sun, but they apply to satellite orbits as well. | |

Bernoulli theorem |
| Answer» Bernoulli’s theorem: 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. | |

What is the applications of Archimedes principle? |
| Answer» 1. To find the volume of a body - : Let W1 and W2 be the weights of body in air and water respectively. If V is volume of body, then from Archimedes principle W1 - W2 = V p g Whereas, p = rho [ loss of weight of body In water = upthrust ] .2. Specific gravity of material of a Solid w.r.t water Specific gravity of body = weight of body in air /weight of equal volume of water = weight of body in air / upthrust = weight of body in air / loss of weight of body In water S. G. = W1 / W1 - W2 3. Condition of flotation of body. | |
