For earthquakes, there is a lapsed time between the arrival of the
p-wave and the s-wave, because the waves travel at different speeds. The length
of this period of time determine the
distance to the epicenter.
Earthquakes create seismic waves. P waves are faster than S
waves. As the P and S waves move out from an earthquake, the P waves get ahead
of the S waves. The distance of a seismic station from an earthquake can be
determined from the time difference between the time of arrival of the first P
wave and the first S wave.
Answer:
Mechanical energy = 145 Joules
Explanation:
Given the following data;
Kinetic energy = 115J
Gravitational Potential energy = 30J
To find the mechanical energy;
Mechanical energy = kinetic energy + gravitational potential energy
Substituting into the equation, we have
Mechanical energy = 115 + 30
<em>Mechanical energy = 145 Joules. </em>
Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;
<em>a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.</em>
<em>b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.</em>
