In this position, his rotational inertia is 2.0 kg m2. During the spin, the dancer pulls the arms close to his body. In this position, his rotational inertia is 1.0 kg m2. Ignore friction with the air or with the floor. If the dancer’s final angular velocity is 5.0 rev/min, what was his initial angular velocity with the arms extended?

Question: The charge of a body is a measure of the imbalance between the number of protons (positive charge) and electrons (negative charge). A body can either lose or gain electrons, leading to a net positive or negative charge, respectively. The formula to calculate the charge () of a body is: ;  where is the charge of electron and is the number of electrons. If a body has 5 x 1018  extra electrons, calculate the charge (Q)  on the body?

Question:  You are asked to test an underground pipe with clean water steadily flowing through. The pipe starts with a large cross sectional area of 450 cm2 and after few meters the presence of debris creates a constriction reducing the pipe cross sectional area to 250 cm2. You are able to check the water speed at the 450 cm2 area and you measure 5 m/s.  Assuming that the water flow is steady, what do you expect to be the water speed at the constriction?
