Justify Equation 6.3 by integration. (b) Consider the thermal energy in an aquifer for which the rocks have a porosity 0.2, a density 3000 kg/ m3, and a specific heat 1000 J/kg-K, and for which the fluid is water.

Is this a question of an answer

When seismic waves hit a fault, the waves are reflected off the fault. seismograph can detect these reflected seismic waves. geologists then use these data to map the fault's length and depth

Gravity, from the center of mass of the box, extending downward normal force, from the floor under the box, extending upward, equal to gravity push force, acting at a point on the box, extending in the direction of motion friction, acting at any point on the box directly opposite the push, extending directly opposite to the motion
