Answer:
The buoyant force is a result of pressure exerted by the fluid. The fluid pushes on all sides of an immersed object, but as pressure increases with depth, the push is stronger on the bottom surface of the object than in the top
Explanation:
Answer:
a)Two adjacent crests
Explanation:
Transverse wave is a moving wave that
in which the point of oscillation is at right angle to the direction of the wave. The particle of the medium of transverse wave usually vibrate at right angle to the wave's direction in up and down movement. Wavelength can be measured in the direction the wave is going can defined as the distance between two successive crest of the particular wave. It can be calculated as Wavelength= velocity/ frequency. Which means where there is higher frequency of the wave, then there will be shorter wavelength.
Hence, transverse wave wavelength can be measured as the distance between Two adjacent crests.

<h2>None of these forces contribute for these vibrations </h2>
Explanation:
The atoms or molecules of the solid substance vibrate at zero degree absolute even , due to kinetic energy of the constituent atoms or molecules .
According to Kelvin , the kinetic energy of these particles should become zero at absolute zero .
But it is found by actual calculations that the kinetic energy of constituent atoms or molecules does not become zero .
Thus all the above forces are not considered as the main cause of these vibration .
Answer:
Arrival times of P and S waves
Explanation:
Seismological recording station has a seismometer that senses that motion in the ground, a clock that records time and a data recorded.
The distance between beginning of the first P wave and the first S wave will give you the time the waves are apart.This time value will be used to find the distance between the seismograph and the epicenter of earthquake and you mark it.This is corresponding distance in km to the time in seconds obtained before.You then find the amplitude of the strongest wave and mark it on the right side of chart.Amplitude is the height on paper of the strongest wave.Using a ruler join the amplitude point and the point where you marked the distance to epicenter.This line will cross the magnitude chart at a point which represents the magnitude of the Earthquake.
Answer:
a
Explanation:
<em>a_c</em><em> </em><em>=</em><em> </em><em>v</em><em>_t</em><em>^</em><em>2</em><em>/</em><em>r</em>
<em>a_c</em><em> </em><em>=</em><em> </em>(0.5)^2/0.03
<em>a_c</em><em> </em><em>=</em><em> </em>8.33 m/s^2
