Is taking coaching of chemistry and physics necessary |
| Answer» Agar aapko school. Me sab samajh me Aa Jaata h then aako coaching ki jarurat nahi Phir aap youtube se or selfstudy se hi bhaut achche marks la sakte ho... Or agar sab kuch samajh nahi Aa raha to aapko coaching le leni chahiye..... Kyuki Phir aap youtube se ya selfstudy karte to aapke sabhi consepts achche se clear nahi ho peyenge.. Or in future ye problem creat karega.... Hope it will help u... ☺️<br>Not important to take coaching ;Try on you tube<br>bro. if you can do self study by own then it doesn\'t<br>Yes phele investment karo tabhi future accha hoga | |

How you find the area of displacement in graph of triangle and rectangle??? |
| Answer» I understand that if the velocity is constant (acceleration=0) throughout the course of motion (where graph shows a rectangle) then it would simply be like playing with equation:(1). velocity=displacement/time(2). displacement=velocity × time =area of rectangle =Velocity-axis × time-axis,putting the value of velocity and time, then getting out the displacement.@diti ur sweet sister...????? | |

Show that impulse of a variable force is equal to area enclosed by force time curve |
| Answer» A\xa0variable force\xa0is a force whose magnitude or direction or both vary during the displacement of a body on which it acts or a\xa0force\xa0whose\xa0direction\xa0or\xa0magnitude\xa0or\xa0both\xa0change\xa0with\xa0time.\xa0The graphical representation is given as:Consider a small displacement element\xa0{tex}\\Delta s{/tex}\xa0under force F, which is represented by a strip KLMN. As the displacement {tex}\\Delta{/tex}s is extremely small, hence force F for entire strip KLMN may be taken as constant.Therefore,\xa0Work done during elementary expansion will be equal to{tex}\\Delta W =F\\Delta x{/tex}= area of strip KLMN ....................................(A)Total work done by the variable force can be calculated by dividing the whole path into such elementary parts and in each case the work done will be equal to area of small shaded strips like KLMN. Therefore, total work done for a given displacement is given by:W = {tex}\\sum \\Delta W=\\sum{/tex} area of various strips = total area under F-s graph .......................................(B)Thus, the work done by a variable force is given by the area under F-s curve. | |

What are Newton\'s Three Laws of Motion? |
| Answer» See the ncert book or hcv u will find the solutions.<br>Yes Yash??<br>Aditi..it is you..??<br>My fb id is (Tidal vishwa) photo of audi car in road<br>Newton\'s Third law of Motion States that:Action and reaction forces are simultaneous forces. There is no cause-effect relation betweenaction and reaction. Any of the two mutual forces can be called action and the other reaction.Action and reaction act on different bodies and so they cannot be cancelled out. The internalaction and reaction forces between different parts of a body do, however, sum to zero.<br>Bye........ .....<br>Newtonís second law of motion :The rate of change of momentum of a body is proportional to the applied force and takesplace in the direction in which the force acts. Thuswhere F is the net external force on the body and a its acceleration. We set the constant ofproportionality k = 1 in SI units. ThenThe SI unit of force is newton : 1N = 1 Kg m .(a) The second law is consistent with the First Law (F = 0 implies a = 0)<br>Me toppr??<br>1) the body remains constant in that state which is continous occured untill the external force required to change state. 2) the momentum is directly proportional to the applied force. 3) every action is equal and opposite reaction.<br>Not topper...ur topper<br>Oh topper pura pdh rhi hai??<br>Newtonís first law of motion is the same law rephrased thus:ìEverybody continues to be in its state of rest or of uniform motion in a straight line, unlesscompelled by some external force to act otherwiseî. In simple terms, the First Law is “Ifexternal force on a body is zero, its acceleration is zero”<br>Im telling laws...ok<br>Laws bata do bhai<br>Equation hi bataye hai behen or bhai<br>????<br>Ye 3 equations hai bhai<br>Newton three laws of motion are 1)v=u+at2)s=ut+1/2at^3)v^=u^-2as. | |

Applications of Newton laws of motion |
| Answer» The three laws of motion formulated by Newton are described below\tLaw of inertia: According to this law a body at rest will remain at rest and a body in motion will remain in motion at the same speed and in the same direction unless acted upon by an external force.\tLaw of acceleration: According to this law, A change in motion is directly proportional to the force producing it and inversely proportional to its mass. If two unequal forces are applied to objects of equal mass, the object that has greater force applied will move faster. Conversely, if two equal forces are applied to objects of different masses, the lighter mass will travel at a faster speed.eg. In hammer throw, a thrower who is stronger will throw the hammer farther than a thrower who is less strong.\tLaw of reaction: According to this law ‘For every action there is an equal and opposite reaction.’<br>Vedantu\'s Abhishek Sir is the Best???? | |

Derive an expression for gravitational potential energy of an object? |
| Answer» We know that every object on the surface of the Earth is attracted by the Earth.So,if an object has a mass\'m\',it will experience a force that is called the weight of the object which acts vertically downwards.To move this object upward from \'a\' to\'b\' through a distance \'h\', we must apply a force \'f\' upward were F=MgW=Fh, but as F=Mg,W=mgh -------(1)This work done on the object which changes its position is called the Gravitational Potential Energy. Then:Ep=w-------(2)From (1) & (2), we get:Ep=mgh | |
