Answer:

Explanation:
Given:
- moment of inertia of the skater with extended arms,

- moment of inertia of the the skater with pulled-in arms,

- angular velocity of the skater with extended arms,

<u>Using the law of conservation of angular momentum:</u>



Answer:

Explanation:
given data:
density of water \rho = 1 gm/cm^3 = 1000 kg/m^3
height of water = 20 cm =0.2 m
Pressure p = 1.01300*10^5 Pa
pressure at bottom



= 1.01300*10^5 - 1000*0.2*9.8
= 99340 Pa
h_[fluid} = 0.307m
