In a free fall object travels moredi what you select as an answer. ct travels more distance in first second of fall or the last second of fall .Explain In Atwood's machine the acceleration is given by:- M2-M1 a= M2+M1 9,M2> M1 What is the net force b) If 5g is transferred from M2 to M1 ( M2>M1) will the net force increase or decreas plain. a) If you push a wooden block of mass m on the horizontal table top and it does not move, frictional force is acting on the block. Draw a free body diagram for this. moves with velocity V considering the velocities j . explain w In hallistic pendulum a ball of mass m with velocity v hits a pendulum of mass M at

Explanation / Answer

Least Count = Pitch / Number of Divisions on the Circular scale

Pitch of the micrometer = 0.5 mm
No of Division = 100

Therefore , Least count = 0.5 / 100 = 0.005 mm

Least count of the micrometer screw = 0.005 mm
