Explain newton 2nd law is real law |
| Answer» Which states that there will be no acceleration in the body if no external force is applied on it.This means that a body in rest will remain at rest and a body in uniform motion will remain in uniform motion which is also stated in Newton\'s 1st law. ... Therefore,2nd law of motion is a real law of motion. | |

Deduce a relation between one light year and one parsec. |
| Answer» Light year is the distance travelled by light in one year. And a parsec is defined as the distance at which one astronomical unit subtends an angle of one arcsecond,[1] which corresponds to 648000/π astronomical units. One parsec is equal to about 3.26 light-years (30 trillion km or 19 trillion miles) in length. | |

Explain centrifugal forcr. |
|
Answer» Tendency of an object following a curved path to fly away from the center of curvature. Might be described as “lack of centripetal force.” No; centrifugal force is the inertia of motion. The direction of centrifugal force is the radius of the circle, from the center towards the object. It is equal to centripetal force in magnitude but opp.in direction |

Impulse is a scalar quantity or vector quantity?? |
|
Answer» Vector Since force is a vector quantity, impulse is also a vector in the same direction. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the same direction. thus it can be concluded that impulse is a vector quantity |
|
| 9419. |
Centrifugal force |
|
Answer» Centrifugal force is the pseudo force which act on an object due to its tendency to regain straight line motion. It is directed away fron center. The force acting towards center is called centrifugal force Centrifugal force directs the body to the centre of the path |

Why gravitational force is conservative?? |
| Answer» A conservative force is a force with the property that the work done in moving a particle between two points is independent of the path taken. The gravitational force is conservative because the work done by the gravitational force on an object depends only on its change in height. | |

What are concurrent forces |
|
Answer» Thax both of u The forces which act at a same point is known concurrent forces If two or more forces act on a point, i.e. line of action through one common point, they are called concurrent forces. Concurrent means meeting at a point.If all the forces are passing through a single point then those forces are called as concurrent forces. |

Why does a body lose weight at the centre of the earth ? |
|
Answer» Wt of the value of g becomes 0 at centre of earth hence body loses wt usney toh mass ki puchi he nhi... but yaa mass doesn\'t change coz it is constant. Wieght zero hai par mass ni hai weight of the body is 0 at the centre of the earth coz there g becomes zero |

what is hydrostatic pressure |
| Answer» The hydrostatic pressure is the pressure exerted by a fluid at equilibrium at any point of time due to force of gravity. Firstly solid objects do not change their shape on the application of pressure which is obviously not the case with fluids. Fluid pressure can be caused by gravity, acceleration or forces when in a closed container. If we consider the layer of water on the top of a bottle, the pressure exerted by the layer of water acts on the container at the sides, the surface of air on top and the layer of water at the bottom. As we move down from the top of the bottle to the bottom, the pressure exerted by the top layer on the bottom adds up. Due to this phenomenon, the fluid at the bottom of the container experiences more pressure that the fluid which is above it. | |

all 3 newton\'s law of motion define |
|
Answer» According to 1st law of motion :- "A body continue in the position of rest or the uniform motion along a straight line . unless external force act on it."According to 2nd law of motion :-" the rate of change of linear momentum is directly proportional to the applide force "According to 3rd law of motion :-"For every action there are equal nd opposite reaction . action nd reaction act on the diff.bodies" Hope it help u a lot☺☺☺☺☺☺☺ 1.if a body is in inertia until or unless any external force is applied.2.the momentum remains constant until and unless any extenal force is applied.3.every action has equal and opposite reaction. |

What is strain? |
|
Answer» When we deal it in physics Stress is The deforming force acting per unit area normal to the surface of the body is normal stress . And so on. strain has dimension of force per unit area, or often, force per unit length. The fractional deformation produced in the body by the external deforming forces is called strain. |
