Correct option A
The wave speed remains constant.So if the frequency increases then wavelength increases and if frequency decreases then wavelength increases to maintain the constant wave speed.

<span>The correct answer to
the question that is stated above is obviously letter b, false.
</span>Seismic waves travel along the Earth’s surface.They are <span>waves of </span>energy<span> that travel through the </span>Earth<span>'s layers. These waves are a result of an </span>earthquake <span>, </span>volcanic<span> eruptions, magma movement and large </span>landslides.
The answer is A because the lighter or heavier the liquid is (in this case it depends) it flows up.
Answer:
The speed decreases and the frequency remains the same.

Answer:
K = 1800 kJ
Explanation:
Given that,
The speed of the object, v = 30 m/s
Mass of the object, m = 4000 kg
We need to find the kinetic energy of the object. The formula for the kinetic energy is given by :
So, the required kinetic energy is equal to 1800 kJ.
