Sound is louder when a vibrating source is held to a sounding board because more surface is forced to vibrate, pushing more air.

True or False?
Physics
1 answer:
irina [24]3 years ago
5 0

Answer: True

Explanation:

A sounding board has the property of receiving a sound wave and transforming it into vibration of the air molecules inside it; resulting in amplification or modulation of sound.

In other words, when the sound waves pass through a sounding board, the resulting sound is louder (amplified) because its surface is forced to vibrate by the air molecules present within the mentioned sounding board.

Answer:

An aqueous stagnant layer that overlies the apical membrane and the subepithelial blood flow are potential barriers to the absorption of drugs that readily penetrate the absorbing cell of the epithelium. The apical, basal, and basement membranes are potential barriers to the absorption of less permeable drugs.

A hot-air balloon is floating above a straight road. To estimate their height above the ground, the balloonists simultaneously m
ki77a [65]
We know that
tan(∅) = y/x; where y will be the height of the balloon and x will be the distance from the milestone marker.
The marker that is further away will produce a smaller angle of depression.
tan(18) = height / x
x = height / tan(18)

The second marker is x + 1 miles away:
tan(16) = height / x + 1; substituting x:
tan(16) = height / (height/tan(18) + 1)
tan(16) x [(height / tan(18) + 1] = height
0.88h + 0.29 = h
h = 2.42 miles

Earthquakes and volcanic eruptions are examples of rapid events that are caused by the movement of Earth's _______. Mountain bui
andrew11 [14]

The correct answer is - C. Crustal plates, crustal plates.

The movement of the crustal plates of the Earth is the reason why the geologic processes are occurring on our planet. With their movement, the crustal plates manage to create lot of pressure, open up gaps for the magma from the mantle, as well as make adjustments deeper into the ground.

Because of the adjustments deep into the ground, or rather the crust, lot of force is released, manifested as strong and very quick vibrations, better known as earthquakes.

The gaps that are opening between the plates let the magma reach the surface, thus enabling the volcanic activities on the planet.

The pressure from the plates' collision makes the land lift up slowly, and over time a mountain range starts to form because of the continuous lifting up of the area.
