CForce Y is responsible for wearing and tearing of tyres of vehicles.
DWe can walk only on those surfaces which offer no Y.

Ritu took two bimetallic strips, I and II (of equal size, length and breadth) made up of metals P and Q; and Q and R, respectively as shown here.
She subjected each bimetallic strip to heating for same time period. The given diagram shows her experiment.

Which of the following cannot be inferred from the above experiment?

AMetal P expands more as compared to metals Q and R on heating for the same time period.
BMetal R contracts more as compared to metals P and Q on heating for the same time period.
CThe ascending order of expansion of these metals when subjected to heating is R < Q < P.
DBoth B and C

Ans 2:

Class : Class 8
D is also correct the player experiences random motion and because he is running after a ball which is in random motion so he is in random motion too. he also experiences oscillatory motion because while he is running his legs ags are going up and down to the extreme points which are the properties of oscillatory motion.

Ans 3:

Ans 4:

Class : Class 6
Ans A also is correct as the motion of the soldiers is uniform that is it is periodic. The motion of the hands is also oscillatory which is periodic
