Lead emission since early 1980s have DECREASE DUE TO LEAD FREE GASOLINE. 
Lead is a natural occurring element that is found in small quantity in rocks and soils. Lead emission is an important environmental health issue because a very small quantity of lead can cause adverse effects on the nervous system of unborn babies and young children. Because of this, the government took all necessary measures to ensure that its emission was drastically reduced.

Answer: TRUE

Explanation:

Sound waves enter the OUTER EAR and travel through a narrow way up to the eardrum, where it vibrates.

The vibrations are sent to the bones of the MIDDLE EAR where they are amplified, and passed to a structure called COCHLEA in the INNER EAR.

Finally, it reaches the sensory cells that passes it to the auditory nerve that transmit the sound to the brain as electrical signals (neural messages) for proper interpretation.

Describe what will happen to the wave as it goes through the hole. what do we call this?​
kari74 [83]

Diffraction occurs when a wave moves through an opening in a barrier. This causes the wave to change direction and spread out.

Waves can behave in three different ways depending on the obstacles they encounter. They can reflect, refract or diffract. In diffraction, waves such as sound, light or water either bend around small objects that obstruct their passage or spread out as they travel through a gap in the barrier.

The degree of diffraction forms a direct relationship with wavelength. It generally increases as wavelength increases. Conversely, the amount of bending lessens as wavelength decreases. However, if the opening of the barrier is smaller than the wavelength, the effect of diffraction is not easily observed. Hope this helps.
