Yes, all waves can be distorted, deflected, or changed
<span>Waves are a means by which energy travels. Many different particles move in waves. </span>All waves can be changed through interference with waves of similar wavelengths.
Answer:
D).happens when soil is weakened by water and seismic waves
Explanation:
Liquefaction is a phenomenon in which the strength of the soil weakens due to the earthquake or any other load. The solid behaves like a liquid. Liquefaction of soil below structures cause lot of damage during Earthquakes.The soil looses stiffness due to seismic waves and water.
Thus, the correct option is D.
The answers are; air, fuel, back, forward
The jet engine utilizes the principle that for every action force there is an equal reaction force in the opposite direction. When the exhaust from the combustion in the engine is ejected with great force backwards, the reaction force pushes the plane forward with an equivalent force.
Answer:
4 seconds
Explanation:
Average acceleration is change in velocity over change in time:
a = Δv / Δt
Δt = Δv / a
Δt = (15 m/s - 5 m/s) / 2.5 m/s²
Δt = 4 s
That statement may be considered true. 'Specific gravity' is the ratio of
the density of a substance to the density of a reference substance. The
reference substance is nearly always water, and the ratio of the density
of water to the density of water is obviously ' 1'. So there you are.
