sp2606 [1]

Answer:

1.98 rev/s

Explanation:

m  = mass attached to each hand = 5 kg

r_{i} = initial distance of masses in each hand = 1 m

r_{f} = final distance of masses in each hand = 0.1 m

I = moment of inertia of body = 5 kgm²

I_{i} = initial total moment of inertia = I + 2 mr_{i}^{2}

w_{i} = initial angular velocity = 1 rev/s

I_{f} = final total moment of inertia = I + 2 mr_{f}^{2}

w_{f} = final angular velocity = ?

Using conservation of angular momentum

I_{i} w_{i} = I_{f} w_{f}

(I + 2 mr_{i}^{2}) w_{i} = (I + 2 mr_{f}^{2}) w_{f}

(5 + 2 (5) (1)^{2}) (1) = (5 + 2 (5) (0.1)^{2}) w_{f}

w_{f} = 2.94 rev/s

Answer:

Explanation:

Geologists record the seismic waves and study how they travel through Earth. The speed of these seismic waves and the paths they take reveal how the planet is put together. Using data from seismic waves, geologists have learned that Earth's interior is made up of several layers.
