That is false. A GPS cant tell latitude and longitude
Answer:
2.The density of air increases and thendecreases as the sound wave passes.
Explanation:
Sound waves are mechanical waves, which consist of oscillation of the particles in the medium where the wave is transmitted through.
Sound waves are also longitudinal waves, which means that the direction of oscillations of the particles of the medium occurs in a direction parallel to the direction of motion of the wave (so, essentially back and forth).
Due to the nature of longitudinal waves, they create alternating regions of the medium where the density of particles are higher and lower. The former are called compressions, while the latter are called rarefactions.
Therefore, when a sound wave travels through the air, the density of one region of air continuously changes: compression first (high density), rarefaction then (lower density), then compression again, etc..
The answer would be C. Lightning occurs when the negative charges from clouds attract towards the positive charges on the ground. These two charges attract and cause the spark of lightning. Hope this helps.
1.2 percent of 155 million is 1,860,000. Divide that by 12 (for twelve months of the year) and get 155,000. That's the answer. 155,000.
