Will the friction increase or decrease if we increase the weight of the object in motionon a surface and why? |
|
Answer» tion:When a body is moving over a horizontal surface, it PRESSES down against the surface with a force equal to its weight, i.e., to the PULL of gravity upon it; an increase in the weight of the body CAUSES an increase in the amount of resistance offered to the relative MOTION of all the surfaces in contact.Hence friction will increase . |

Prove the second equation of motion graphically and define the slope of the graph |
|
Answer» Proof of the second equation of motion graphically is as follows,Let us consider a BODY which is moving with the initial velocity vi.Then the final velocity of the body is vf with the time t in sec.The distance traveled =S, then the acceleration of the body is indicated as a.That is, Initial velocity =viFinal velocity = vfTime TAKEN =tAcceleration=aDistance=SSo now, let us consider the speed of the body by OA which as initial velocity as vi and OC the speed of the body OC at final velocity vfThen the slope of the graph AB will REPRESENT acceleration of the body with a.S=area of OABCS= area of rectangle OADC+ area of triangle ABDThen S=(vi)(t)+1/2(AD)(BD)By substitution we GET the above expression to be as,\bold{S=(v i)(t)+1 / 2 a t^{2}}S=(vi)(t)+1/2at 2 |

Answer» A dipole of dipole MOMENT p is placed in a NON uniform electric field along x axis. electric field is increasing at the rate of 1v/m then the force on dipole is...Answer : force on dipole = p explanation : given, A dipole of dipole moment p is placed in a non-unifrom electric field along x - axis. Let US CONSIDER that E(x) is electric field along x-axis. now, electric field is increasing at the rate of 1 V/m . i.e., dE(x)/dx = 1V/m.we know, force due to dipole is given by, F = dipole moment × electric field gradient = p × dE(x)/dx = p × 1 = p Hence, force on the dipole should be p ✔ |
