This question involves the concepts of wave speed, wavelength, and frequency.
The frequency of the wave in seawater will be "2.68 Hz".
<h3>FREQUENCY</h3>
The relationship between speed, wavelength, and frequency of the wave can be given by the following formula:
Here, the wavelength of the wave is a constant property. Therefore,
where,
- v₁ = speed of the wave in the rock = 3950 m/s
- v₂ = speed of the wave in the seawater = 1500 m/s
- λ = wavelength = 560 m
- f₁ = frequency of the wave in the rock =
- f₂ = frequency of the wave in the seawaater = ?
Therefore,
f₂ = 2.68 Hz

Answer:
A. A potential energy function can be specified for a conservative force.
TRUE
because there is no loss of energy in conservative type of forces.
B. A nonconservative force permits a two-way conversion between kinetic and potential energies.
FALSE
It is not true because energy is not conserved in non-conservative forces.
C. The work done by a nonconservative force depends on the path taken.
TRUE
It depends on total path length while in conservative it only depends on initial and final state
D. A potential energy function can be specified for a nonconservative force.
FALSE
Since energy is not stored in non-conservative forces so it is not defined for non conservative forces
E. A conservative force permits a two-way conversion between kinetic and potential energies.
TRUE
Work done against conservative forces is stored in form of potential energy so it is possible to have two way conversion.
F. The work done by a conservative force depends on the path taken.
FALSE
Conservative force work depends only on initial and final state
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.
Answer:
in 90 seconds It'll travel 450m At constant speed of 5m/s
The capacitance is defined as the maximum charge stored in a capacitor, Q, divided by the voltage applied, V:
The capacitor is initially charged with the battery of 108 V, so the the initial charge on the capacitor can be found by re-arranging the previous formula:
