When a sound wave travels through air, how is this air affected by its passage

Sound is a mechanical wave <span>that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. If a sound wave is moving from left to right through air, then particles of air will be displaced both rightward and leftward as the energy of the sound wave passes through it. The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. This is what characterizes sound waves in air as longitudinal waves.</span><span>

What is the netforce of the dog ​thanks!
kakasveta [241]

Answer:

5 Newtons Up and 5 Newtons Right

Explanation:

Treat each force vector as a value and choose the upward and rightward directions to be positive. Downward and Leftward forces will be considered "negative". For the vertical net force we have a positive 10 N upwards and a negative 5 N downwards. The net force in the vertical will be 5 N upwards. In the horizontal we have 10 N to the right and 5 N to the left. The net force in the horizontal will be 5 N to the Right.

It is easier if you split the motion into horizontal and vertical components.

A plane is flying with an airspeed of 190 miles per hour and heading 150°. The wind currents are running at 30 miles per hour at
OverLord2011 [107]

Answer:

Vg=200mile/hr

\theta=153 \textdegree

Explanation:

From the question we are told that:

Plane airspeed v_p=190mil/h

Plane direction \angle=150 \textdegree

Wind current speed V_w=30mil/h

Wind direction \angle=150 \textdegree

Generally the vector form of the forces is mathematically given by

For plane

\angle Q_p=90-150 \textdegree

V_p=170(cos60 \textdegree ,sin60 \textdegree)

V_p=(85,-147.224)

For wind

\angle Q_w=90-170 \textdegree

V_w=30(cos-80 \textdegree ,sin-80 \textdegree)

V_w=(5.2,-29.54)

Generally the equation for resultant force is mathematically given by

v_r=V_a+V_w

v_r=(85,-147.224)+(5.2,-29.54)

v_r=(90.21,-176.76)

v_r=198.45\angle -63

Therefore ground speed

V_g=198.5miles/hr

Vg=200mile/hr

Direction

\theta=(90+63)=153 \textdegree

\theta=153 \textdegree
