Explanation:
The greatest concentration of atomic mass is in the nucleus because it is made up of protons and neutrons. The electrons surrounding the nucleus don't have as much mass as protons or neutrons.
Hopefully this helps...
The conservation of energy equation?
K1 + U1 = K2 + U2
Or the Kinetic energy equation?
KE = 1/2 mv²
Gravitational potential energy?
Ug = mgΔy
Elastic potential energy?
Ue = 1/2 kx²
Answer:
A. Sound waves can travel through and reflect off rock layers.
Explanation:
Reflection seismology is a process of "seeing" below the ground using artificial sources to create sound waves or the process of learning about rock layers beneath the surface of Earth using sound waves.
Sources on land, uses vibration trucks to shake the ground very powerfully to produce sound waves.
Thus, the sound waves will travel through the earth and reflect off rock layers having different acoustic properties. In order to record this reflections, we make use of a small instrument called geophones.
