bernoulis theorem states that total energy of steady or terbulant flow is always contsant.... that is (pressure energy + kinetic energy + potential energy= constant) here anew kind of energy that is pressure energy is always present in fluid (you may have learnt in gas laws PV=nRT here PV is the pressure energy) hence we can say that for a steady flow..
PV+1/2mv^2+mgh=constant.... dividing both sides by V what do we get is the bernuolis theorem...

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
deviation (a) at 40 latitude, (b) at the poles, and (c) at the equator

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
