Statement1: |
When a diver dives, the rotational kinetic energy of the diver increases during several somersaults |
Statement2: |
When diver pulls his limbs, the moment of inertia decreases and on account of conservation of angular momentum his angular speed increases |
a) |
Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1 |
b) |
Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1 |
c) |
Statement 1 is True, Statement 2 is False |
d) |
Statement 1 is False, Statement 2 is True |
