Draw the graph showing the variation of force of friction with the applied force. |
| Answer» Apne ye attachment kaise share kiya .Please tell me. Yogita Ingle.<br>This is for static friction.<br>The Graph plotted for the friction and the Force applied on it is attached in the attachment.From the Attachment, We can see there is a small kink at the top which means after the static friction has been reached a maximum value with the increment in the force applied on it, there is a little decrease in the friction which is just the kink.Also, we can see that the line is making an angle of 45° with the x-axis. After some time the Force of the friction become constant with the increase in force there is no effect of the Friction, since it became the constant.<br>Mujhe kuch nahi hua h .tumhe kya parashani h.<br>Kya hua sis.....ji | |

Give the factors on which the static frictional force depends upon |
| Answer» Depends on Area of contact<br>\u200b\u200b\u200b\u200bStatic friction is a force that keeps object at rest. It must be overcome to start moving the object.Factors on which the static firctional force depends:1) Force exerted by the body on the surface.2) Contact surface if they were rough, then friction between their surface is more and vice versa. | |

Define 1 redian |
| Answer» The radian, denoted by the symbol, is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics. The length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it subtends; one radian is degrees or just under 57.3° | |

what is parallax method? with example |
| Answer» Parallax is the displacement or the change in the apparent position of the object when viewed from two different points of view. The two points of view have their own line of sights and parallax is measured as half of the angle between the two lines of sights.When you are traveling in a vehicle and you look around as you are moving, you will see that objects in the distances appear to move more slowly than the objects closer to you. This is the effect of parallax. Nearby objects have a larger parallax than the distant objects, so the parallax can be used to determine distances.The phenomenon of parallax, when combined with triangulation, will yield the location of the object with considerable accuracy. Astronomers regularly use the parallax method to measure the distances of the closer stars. | |
| 2884. |
Define Angular displacement...... |
| Answer» Angular displacement\xa0is defined as “the angle in radians (degrees, revolutions) through which a point or line has been rotated in a specified sense about a specified axis”. It is the angle of the\xa0movement\xa0of a body in a\xa0circular\xa0path.\xa0Angular displacement is measured in units of radians. Two pi radians equals 360 degrees. The angular displacement is not a\xa0length\xa0(not measured in\xa0meters\xa0or feet), so an angular displacement is different than a linear displacement. | |
| 2885. |
Tell about rotation motion |
| Answer» Thanks<br>The\xa0motion\xa0of a rigid body which takes place in such a way that all of its particles move in circles about an axis with a common angular velocity; also, the\xa0rotation\xa0of a particle about a fixed point in space.\xa0Rotation around a fixed axis or about a fixed axis of revolution or motion with respect to a fixed axis of rotation is a special case of rotational motion. The fixed-axis hypothesis excludes the possibility of an axis changing its orientation and cannot describe such phenomena as wobbling or precession. | |

What is frame of reference. Explain in detail with example |
| Answer» Simply- origin<br>When a clock is put in the Cartesian coordinate system and origin supposed to be a reference object then such Cartesian coordinate system is known as frame of reference<br>The point of intersection of these three axes is called origin (O) and serves as the reference point.This coordinate system along with a time constitutes a frame of reference<br>Frame of ReferenceIn order to know the change in position of an object, a reference point is required. Point O in the figure is the\xa0reference point or Origin\xa0and together with three axes, this system is called the\xa0coordinate system. A coordinate system with time frame is called\xa0frame of reference.\tObjects changing positions with time with respect to the frame of reference are in motion while those which do not change position are at rest.\tFor a moving car, for the frame of reference outside the car, it appears moving. While for the frame of reference inside the car, the car appears stationary.<br>frame of reference can be defined as an observer with a clock at origin. e.g put a pen in front of you close your on eye and see the tip of pen and then repeat it with other eye then two frames are formed. | |

Differentiate angle of repose and angle of friction and give relation between them |
| Answer» Angle of Friction beween any two surface in contact is defined as the angle which the resultantof the force of limiting friction Flim\xa0and normal reaction N makes with the direction of normal reaction Nas shown in figure. It is marked in the figure as\xa0θ.The value of angle of friction depends on the material and nature of surfaces in contact.\xa0It can be seen from figure, tanθ = AC/OA = Flim\xa0/ N =\xa0μ , where\xa0μ is coefficient of limiting friction--------------------------The angle of repose or angle of sliding α is defined as the minimum angle of inclination of a planewith the horizontal such that a body placed on the plane just begins to slide down.Its value depends on the material and nature of the surface in contact.\xa0from the figure it can be seen that, f =mg sinα ...............(1)N = mg cosα ....................(2)hence we get, f / N = tan\xa0α =\xa0μ | |
