An experimenter measures the length of a rod. In the cases listed, all motions are with respect to the lab and parallel to the length of the rod.

(a) If the car is moving on straight road

a– (ii); b– (i); c– (iii).

The wheel of a moving bicycle depicts circular as well as rectilinear motion whereas a blade of a moving electric fan shows only circular motion.

(d)1/2 mw2l. Explanation:  Since the rod rotates on the horizontal surface, the horizontal component of the force applied by the clamp is the centripetal force = mω²r = mω²(l/2) = ½mω²l.

(c) Both A and B are true

(c) the length will decrease (d) the mass will increase.

(a) The density continuously increases from left to right (b) The density continuously decreases from left to right Explanation:  Assume the parts of the rod on left and right from the middle as...

The correct answer is b. i-P; ii-M; iii-N; iv-O

vector B = (7.0i – 3.0j) × 10–3T vector a = acceleration = (---i + 7j) × 10–6m/s2 Let the gap be x. Since vector B and vector a are always perpendicular vector B...

(d) Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Tectonic plates are able to move because the Earth’s lithosphere...
