A wire of length 150cm and area of cross section equal to 1mm stretched by a weight of 3 kg. Find the increase in length.
Young's modulus of the material of the wire = 2x10' N/m (g

Why are graphs useful when interpreting data

What is the angular momentum of the bar about the axle?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
