The statement which describes the location of an earthquake’s epicenter is: D. It is located at the point where circles intersect on a map.

An earthquake can be defined as a sudden, natural shaking of the ground, as a result of movements within the Earth's crust and upper mantle (lithosphere) that typically creates seismic waves.

A seismograph refers to an instrument that is designed and developed for detecting, monitoring and recording the direction, duration and magnitude (intensity) of an earthquake in a geographical location on planet Earth.

An epicenter is the point on the surface of planet Earth, which is perpendicular to the hypocenter (focus) and it indicates where the seismic waves from an earthquake are most intense.

On a map, an earthquake’s epicenter is located at the point where the three (3) circles intersect because earthquake are generally shallow.

It is located at the point where circles intersect on a map.

Explanation:

The name 'EPICENTER' was formed by a seismologist from Ireland can Robert Mallet.

An epicenter of an earthquake can be defined as the exact point in the center where as earthquake originated from.

An epicenter of an earthquake can also be defined as the point that is located directly above the focal point of an earthquake.

In other to be able to accurately determine the exact place where an earthquake happens, seismologist try to find out the distance of the earthquake from at least three seismic recording stations. The distance of the earthquake is obtained from a an equipment used by seismologist called seismograph. After obtaining the values if this distance, circles with the right radius are then drawn around each station. The point where the three circles meet or intersect shows us the earthquake's epicenter.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge, $v = \dfrac{e_p}{q}$ then the following gives us the potential difference, $\delta v = v_b - v_a$ $\begin{aligned} \delta v & = \dfrac{e_p_b}{q} - \dfrac{e_p_a}{q} \\ & = \dfrac{\delta e_p}{q} \end{aligned}$ the formula $\delta v = \delta e_p / q$ may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get $\delta e_p = q\delta v$ using q = 8.00 × 10⁻¹⁹ c and δv = 2.00 v, we get $\begin{aligned} \delta e_p & = (8.00\times10^{-19} \text{ c})(2.00\text{ v}) \\ & = 1.60\times 10^{-18}\text{ j} \end{aligned}$ the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?
