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.

beks73 [17]

Answer:

I belive that the 2000 kg will be going faster then the 1000kg

Explanation:

Because it is 2x as heavy as the other car which means it most likely would hit the car and keep going because it can hit it so hard that the car dosent hit effected

A car moving at 44 km/ h skids 16 m with locked brakes. How far will the car skid with locked brakes at 110km/ h
svp [43]

Answer:

100 m

Explanation:

44 km/h = 12.2 m/s

110 km/h = 30.6 m/s

Given:

Δx = 16 m

v₀ = 12.2 m/s

v = 0 m/s

Find: a

v² = v₀² + 2aΔx

(0 m/s)² = (12.2 m/s)² + 2a (16 m)

a = -4.67 m/s²

Given:

v₀ = 30.6 m/s

v = 0 m/s

a = -4.67 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (30.6 m/s)² + 2 (-4.67 m/s²) Δx

Δx = 100 m

The specific heat of copper is 0.385 J/g•°C. Which equation would you use to calculate the amount of heat needed to raise the te
Pavlova-9 [17]

Answer:

Q = 0.75 g x 0.897 J/g•°C x 22°C

Explanation:

The amount of heat needed to raise the temperature of a substance is given by the equation

Q=m C \Delta T

where

m is the mass of the substance

C is the specific heat capacity

\Delta T is the increase in temperature of the substance

In this problem, the mass of the aluminium is m=0.75 g. The specific heat of aluminium is C=0.897 J/g•°C, while the increase in temperature is

\Delta T=29^{\circ}-7^{\circ}=22 ^{\circ}

So, the equation becomes

Q = 0.75 g x 0.897 J/g•°C x 22°C

A small metal sphere has a mass of 0.11 g and a charge of -21.0 nC . It is 10 cm directly above an identical sphere with the sam
GrogVix [38]

Answer:

A. the magnitude of the force between the spheres is 3.97 x 10⁻⁴ N

B. the magnitude of its initial acceleration is 5.83 m/s²

Explanation:

given information:

metal sphere's mass, m = 0.1 g = 1 x 10⁻⁴ kg

charge, q = -21 nC = -2.1 x 10⁻⁸

r = 10 cm = 0.1 m

What is the magnitude of the force between the spheres?

F₁₂ = k q₁q₂/r²

     = ( 9 x 10⁹) (-2.1 x 10⁻⁸)²/(0.1)²

     = 3.97 x 10⁻⁴ N

If the upper sphere is released, it will begin to fall. What is the magnitude of its initial acceleration?

mg - F₁₂ = ma

a = g - (F₁₂/m)

   = 9.8 - (3.97 x 10⁻⁴/1 x 10⁻⁴)

   = 5.83 m/s²
