-Dominant- [34]

Answer: Forensic science

In early 1800s, the professional investigators regularly attend court trial to answer questions related to physical evidence, which is described as forensic science. The study of physical evidence is a practical tool to assist police in conducting investigations by developing a sense of how the crime was committed. Therefore, the application of forensic science is a great help in solving crime.

PLZ HELP!<br> Which is NOT an example of a longitudinal wave?
LenaWriter [7]

The 1st example is NOT a longitudinal wave

Explanation:

Waves are periodic disturbance of the space that travel carrying energy but not matter.

Depending on their vibration, waves are classified into two types:

  • Transverse waves: in transverse waves, the vibration of the wave occurs in a direction perpendicular to the direction of propagation of the wave. Examples of transverse waves are electromagnetic waves.
  • Longitudinal waves: in longitudinal waves, the vibration of the wave occurs in a direction parallel to the direction of propagation of the wave (back  and forth), creating regions of higher particle density (compressions) and lower particle density (rarefactions). Examples of longitudinal waves are sound waves.

In  this problem we have four options given:

  1. The first picture represents a transverse wave, because the vibration of the robe is up and down, while the wave propagates on the left-right direction
  2. The second picture represents a sound wave, which is a longitudinal wave
  3. The 3rd picture represents a longitudinal wave, since the vibration of the slinky is back and forth along the direction of propagation
  4. The 4th picture also represents a sound wave, which is longitudinal

Therefore, the only wave which is not longitudinal is the one in the 1st picture.

A ships initial position is 25 km east of the origin. What is the ship’s final position if it sails at a constant velocity of 42
Evgen [1.6K]

Answer:

88km E

Explanation:

25 km is added already

then if we take the formula of speed(V)

V=d/t

and rearrange it to subject d (distance)

d= V x t

we get

d= 42km/h x 1.5hrs

we get

63 km

now if we add the already travelled 25 km to this additional distance

63km + 25km = 88km

Thus the final distance traversed by the ship from its origin is

88km E
