A sound wave is a longitudinal wave caused by vibrations and carried through a substance. The particles of the substance, such as air particles, vibrate back and forth along the path that the sound waves travel. Sound is transmitted through the vibrations and collisions of the particles.

The tension in the rope securing the upper pulley and the force that must be applied to keep the system in equilibrium ​
chubhunter [2.5K]

Answer:

Explanation:

In a frictionless system with no acceleration, the tension in the rope must be F along its entire length

FBD analysis of the lower pulley has two upward acting tension vectors F and one downward acting weight vector W

2F = W

F = W/2

FBD analysis of the upper pulley has one upward acting support vector T and three downward acting tension vectors F

T = 3F

T = 3(W/2)

T = 1.5W

An ice skater spins at 2.5 rev/s when his arms are extended.He draws his arms in and spins at 6.0 rev/s. By what factor doeshis
Amiraneli [1.4K]

To solve this problem we will apply the concept related to Angular momentum. Said conservation momentum says that its initial state must be equal to that of the final state, that is,

L_f = L_i

\omega_f I_f = \omega_i I_i

Here,

I = Moment of Inertia

\omega = Angular velocity

Rearranging to find the ratio between the moment of inertia we have,

\frac{I_f}{I_i} =\frac{\omega_i}{\omega_f}

Replacing,

\frac{I_f}{I_i}= \frac{2.5}{6.0}

\frac{I_f}{I_i} = 0.42

Therefore the correct option is C.
