    High School Find Force Req'd to Move Object: Weight & Calc Mu=F/Normal Reaction

    when we say a weight of 50 kg is kept on a table, then is it 50 kg ? and force applied vertically down is 50x9.81 kgf?In earlier days this Newton unit was not there , it is confusing.pl help.

    High School Find Force Req'd to Move Object: Weight & Calc Mu=F/Normal Reaction

    I want to know the fundamentals of finding the force reqd for moving a stationary object such as a car or a segway (which has got two wheels). Also let me know in a formula mu = F/ NORMAL REACTION, WHAT IS THE VALUE OF A WEIGHT HAS TO BE TAKEN? meaning if weight of a person standing on a...

    Bullet Hits Disc: Velocity of Inelastic Collision

    yes there is a diagram it shows, a circle with radius r, centre O, says mass M, THE ARROW TOUCHING THE CIRCLE PERIPHERY TANGENTIALLY . WITH VELOCITY v AND MASS m I thought the text was quite sufficient. Now nothing more to share

    Find value of resistance to get max power in circuit

    Thank you Sir. Actually the power is required from the whole circuit and not from the unknown resistsnce. Will you please help to get the answer for value of unknown resistance for getting max power?

    Find value of resistance to get max power in circuit

    SGT Sir, Can you please calculate and show how to find out value of R by derivative method? Hammie Sir, This seems to be a different approach.What is impedence?Please explain your method to find value of "resistance.
