Explanation :

Sound waves are the longitudinal waves. In longitudinal waves, the particles of the wave move parallel to the direction of propagation of waves.

It moves in the form of compression and rarefaction. When the particles are compact in a space the compression occurs while when they far apart form each other rarefaction occurs.

So, the correct option is (b) " Sound waves are longitudinal waves".

If the car went 30 km west in 25 min. and then 40 km east in 35 min., what would be its total displacement?
ozzi
Displacement only contain the length of movement and the direction of that movement
So you can pretty much disregard the speed.

30 to the west than 40 to the east

The displacement will be 10 km to the east

Reil [10]

Complete question

A cannon with a muzzle velocity of 500. meters per second fires a cannonball at an angle of 30.° above the horizontal. What is the vertical component of the cannonball's velocity as it leaves the cannon?

A   0.0 m/s

B    250. m/s

C   433 m/s

D    500. m/s

Answer:

The correct option is  C

Explanation:

From the question we are told that

   The velocity is  v  = 500 \ m/s

    The angle is  \theta = 30^o

   

Generally the vertical component of the canon ball is mathematically represented as  

          v_y = v * cos (30 )

=>       v_y = 500 * cos (30 )

=>       v_y = 433 \ m/s
