A tsunami wave is different than a normal wave because it is caused by an sudden displacement in the ocean. a earth quake below the ocean floor, a landslide, or a meteorite impact. normal waves are caused by the wind, weather and tides, unlike tsunamis. the long wavelengths from the impact from a earthquake can make the wave slow down and increase the amount of water + height for the wave, making a larger impact wave, a tsunami

Answer:

tsunamis are waves created from A tsunami is a catastrophic ocean wave that is usually caused by a submarine earthquake, an underwater or coastal landslide, or the eruption of a volcano. Tsunamis can also result from the impact of a meteor or comet in a body of water. when one of these events happen all the water near the shore of it will drawn back toward where the tsunamis will form, the waves emerge into one and a tsunamis born, unlike normal waves the tsunami move very fast and they can get very big and more devastating.

a wave is caused by wind, The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules. Stronger winds cause larger waves and a lot of them are not as dangerous as tsunamis, however that's not always the case, since waves like  Rogue waves are big and powerful enough to sink ships, ocean liners, and even oil platforms, same with tsunamis.

At a rock concert, a dB meter registered 130 dB when placed 2.5 m in front of a loudspeaker on stage. (a) What was the power out
kipiarov [429]

Answer:

785.398 W

444.5698 m

Explanation:

I = Intensity of sound

r = Distance

The intensity of sound is given by

\beta=10log\frac{I}{I_0}\\\Rightarrow 130=10log\frac{I}{10^{-12}}\\\Rightarrow 13=log\frac{I}{10^{-12}}\\\Rightarrow 10^{13}=\frac{I}{10^{-12}}\\\Rightarrow I=10^{-12}\times 10^{13}\\\Rightarrow I=10\ W/m^2

Power

P=IA\\\Rightarrow P=I4\pi r^2\\\Rightarrow P=10\times 4\pi\times 2.5^2\\\Rightarrow P=785.398\ W

The power output of the speaker is 785.398 W

If \beta=85\ db

\beta=10log\frac{I}{I_0}\\\Rightarrow 85=10log\frac{I}{10^{-12}}\\\Rightarrow 8.5=log\frac{I}{10^{-12}}\\\Rightarrow 10^{8.5}=\frac{I}{10^{-12}}\\\Rightarrow I=10^{-12}\times 10^{8.5}\\\Rightarrow I=10^{-3.5}\ W/m^2

P=IA\\\Rightarrow P=I4\pi r^2\\\Rightarrow r=\sqrt{\frac{P}{I4\pi}}\\\Rightarrow r=\sqrt{\frac{785.398}{10^{-3.5}\times 4\pi}}\\\Rightarrow r=444.5698\ m

The distance would be 444.5698 m

An argon gas occupies 56.2 L at 760 torr. If the volume of gas dereases to 1/4 of the original volume ,calculate its final press
Elina [12.6K]

Answer:

3040 torr

Explanation:

Applying,

PV = P'V'..................... Equation 1

Where P = Initial Pressure, V = Initial volume, P' = Final pressure, V' = Final volume.

Make P' the subject of the equation

P' = PV/V'................. Equation 2

From the question,

Given: P = 760 torr, V = 56.2 L, V' = 56.2/4 = 14.05 L

Substitute these values into equation 2

P' = (56.2×760)/14.05

P' = 3040 torr

Tomtit [17]

Answer:

4 meter per second square is the acceleration

Explanation:

Force=mass x acceleration

8N= 2kg x acceleration

8N/2kg = acceleration

4 meter per second square is the acceleration.

According to kinetic theory, which two factors are important for a successful reaction to occur?
fgiga [73]

Answer:

Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. Molecules must collide with the proper orientation.

Explanation:

A collision that meets these two criteria, and that results in a chemical reaction, is known as a successful collision or an effective collision.
