Why hammers with long handels preferred |
|
Answer» Ha bhai agar hammer ka handle chota hoga to we will need to provide more effective force to provide any change.. Moment if force depends on two factors - magnitude of force and and perpendicular distance of the line of action of the force and axis of rotation. Hence long handels means more perpendicular distance hence more force would be exerted |

Is escape velocity and escape speed both are same?? |
|
Answer» The correct term is ‘escape speed’. While others argue that you must be traveling in a certain direction in order to escape the gravitational pull of the primary, they neglect to say that the term ‘escape velocity’ is almost never used along with a direction in which the object is moving. If you want to use the term ‘velocity’, then you must give a direction. If you don’t, then you are simply adding to the obfuscation that already exists between these terms. On a moon or another body with negligible atmosphere, you can move in almost any direction you like at the escape speed and still escape the body’s gravity. The only requirement on your direction is that you don’t end up hitting the body itself. It is not the velocity that is limiting you; it is the speed. These two words are so conflated in popular culture already; it’s time to de-conflate them. But Priya Dharshini, you have described Escape velocity...what about escape speed? If I m wrong then correct me I think they both are same....bcoz speed also depends on magnitude ....and escape velocity also says that at what magnitude we throw anything so it goes outside the earth field ... Escape velocity is the minimum vertical speed required to over come the gravitational pull of the Earth and to leave its orbit. Escape velocity for the Earth is relatively constant and is approximately 7 miles/s. |

What are the advantages of Dimension? Mainly five. |
|
Answer» Thank you 3.Defining dimentionless constants or units that would make the physical effect to be studied easier.For e.g. Prandtl number, Reynolds number. This is a major implication of dimentional analysis in highly dynamic systems.4.Reducing the number of experiments to be conducted. When a dimentionless quantity is formulated, the combination of experiments required for describing in them will be less when compared to the large number of participant variables in correlation. Conversion from one units to anotherPreliminary test for validity of equationCorrelation of various parameters in an experiment to understand the relationship between them to form an empirical relationship.

Answer» Ha bhai dekhe your logic was great but koi nahi by the way koun sa subject hai tumhara bio,maths And ya I had solved ur thief wala question ? ??hehe sry 4 that... Mujhe lagta Hai ki Mera logic logo ko samajh aayega ki nhi... ?☺️ Aman bhai tumhara bas ek hi disadvantage hai ki tum last me jake please correct me likh dete ho....kya hai aanswer sahi hai fir bhi aisa mat kar bhai humlog ka confidence ka to dhajiya hi udd ja raha hai I think carriage will not move.. Bcoz person will also become the part of the system..... Don\'t know it correctly, if wrong then correct me |

Why bicycle in motion doesn\'t fall but bicycle fall as soon as it comes to rest? |
| Answer» If the bicycle is at rest, it will be acted upon by downward force ( ,where is mass and is acceleration due to gravity). If it is affected just by this force, it should have stood without falling, because there is no force which pulls it to either side to make it fall. This is the reason why it fall in rest or while slowing down. When u r riding it u exert force by paddling the cycle by ur legs . The force gets balanced hence it will not fall during riding | |

What is translational equilibrium and rotational equilibrium |
| Answer» An object is in translational equilibrium when the sum of all the external forces acting on the object equals zero. This also means an object is in translational equilibrium when it is experiencing zero overall acceleration. Therefore, it is either not moving or moving at a constant velocity.Rotational equilibrium an object is in rotational equilibrium when the sum of all the external torques acting on it equals zero. In rotational equilibrium, an object either will not be moving or moving at a constant angular velocity. This must mean the object is experiencing zero angular acceleration. | |

What is collisions? |
|
Answer» When two bodies collide to each other and exert relatively strong force to each other .....this is termed as collision...? In simple word :- The process of transfer of momentum btw two bodies is termed as Collision The meeting of particles or of bodies in which each exerts a force upon the other, causing the exchange of energy or momentum. |

Please Explain examples of inertia of motion? |
|
Answer» One\'s body movement to the side when a car makes a sharp turn. Tightening of seat belts in a car when it stops quickly. A ball rolling down a hill will continue to roll unless friction or another force stops it. When a bus starts suddenly we tends to fall bachward due to inertia of motion |

Examples of gravitational force |
|
Answer» attractions between table and chair in a room The attraction between any two particle by virtue of their masses is referred as gravitational force. It is universal force. The gravitational force is the force of mutual attraction between any two objects by virtue of their masses. It is a universal force. Every object experiences this force due to every other object in the universe. All objects on the earth, for example, experience the force of gravity due to the earth. In particular, gravity governs the motion of the moon and artificial satellites around the earth, motion of the earth and planets around the sun, and, of course, the motion of bodies falling to the earth. It plays a key role in the large-scale phenomena of the universe, such as formation and evolution of stars, galaxies and galactic clusters. |
