Answer:
For each second the position increased by 10 m
Answer:
Object A has the greater volume by 1.6 cm³.
Explanation:
Density = mass / volume
Solving for volume:
Volume = mass / density
For object A:
V = 12 g / (3 g/cm³)
V = 4 cm³
For object B:
V = 12 g / (5 g/cm³)
V = 2.4 cm³
Object A has the greater volume by 1.6 cm³.
Answer:
exactly 5.88 J
Explanation:
Let's calculate the initial total mechanical energy of the vase when it starts its fall, from a height of 0.750 m. At that moment, the vase does not have kinetic energy, but only potential energy. So, its total mechanical energy is given by:
When the vase falls and reach the position at 0.500 m, part of this energy has been converted into kinetic energy, However, the total mechanical energy is constant, because there are no frictional effects: therefore, the total mechanical energy at 0.500 m above the floor is still equal to the initial total mechanical energy, 5.88 J.
Explanation:
Seismic refraction is the bending of the seismic waves as they pass geological layers of the earth due to different densities. This is especially true for Primary waves because they can pass through all the layers of the earth both liquid and solid.
Seismic reflectivity is the bouncing back of seismic waves at a boundary of geological layers due to different densities or subsurface formation. This is especially true for secondary waves that are unable to pass through liquid layers of the earth like the outer core and mantle. When they reach the boundary of these layers they bounce back towards the earth's surface.
These properties of P and S waves are used to ‘auscultate’ the epicenter of an earthquake by triangulation.
