Answer:
The applied torque is 3.84 N-m.
Explanation:
Given that,
Moment of inertia of the wheel is 
Initial speed of the wheel is 0 (at rest)
Final angular speed is 25 rad/s
Time, t = 13 s
The relation between moment of inertia and torque is given by :

So, the applied torque is 3.84 N-m.
Most waves approach the shore at an angle. However, they bend to be nearly parallel to the shore as they approach it because when a wave reaches a beach or coastline, it releases a burst of energy that generates a current, which runs parallel to the shoreline.
- Most waves approach shore at an angle. As each one arrives, it pushes water along the shore, creating what is known as a longshore current within the surf zone.
- Waves approach the coast at an angle because of the direction of prevailing wind.
- The part of the wave in shallow water slows down, while the part of the wave in deeper water moves at the same speed.
- Thus when wave reaches a beach or coastline, it releases a burst of energy that generates a current, which runs parallel to the shoreline.

Answer:
Nature of Sound Waves Sound is a wave that is created by <u>perturbations</u> and propagated through a <u>medium</u> from one location to another. Type of Wave: <u>longitudinal wave</u><u>.</u> A sound wave consists of a repeating pattern of high-pressure and low-pressure regions moving through a medium Sound needs a <u>medium of propagation</u> and a <u>disturbance.</u> Like any wave, the speed of a sound wave refers to how fast the disturbance is passed from particle to particle.
