Answer:
<h3>The statement is true.</h3>
Explanation:
- The Multiple Nuclei Model developed by Chauncey Harris and Edward Ullman in 1945. They were eminent geographers who described the importance of a city's layout. Their model of city layout consisted of nine different sections which all had separate functions.
- According to the their model, cities do not have one center which contributes all of the growth, but rather have numerous centers of development based on specific urban needs or activities.
- They termed these developing centers as a nucleus and as cities began to grow rapidly, they annexed formerly outlying and independent townships that had been communities in their own right.
The correct answer is its temperature. The clump of colored fluid at the bottom of the lava lamp rises to the top because the clump being the heavier liquid will absorb the heat and it will expand, making it less dense and it starts to rise. Once it rises, it cools down, making it denser and heavier.
Answer:
equivalence principle. Particles follow geodesics that are extremal paths in spacetime. These paths are the same for any mass m so long as this test mass is small m << M for M the mass of a central mass that defines a gravity field. If the spacetime curvature is due to a gravity wave or some other physics, the curvature of this field R is such that R >> 8πGm^2. If this test mass is sufficiently large it has its own appreciable curvature and this results in a highly complex problem similar to the 3-body problem in Newtonian mechanics.
I have though been thinking about this a bit differently. The equivalence principle states that the freely falling frame is equivalent to a frame in flat spacetime far removed from any gravity field. I have been thinking of this according to quantum field theory. A freely falling frame is one which has a vacuum equivalent to a quantum vacuum in flat spacetime. The geodesic the frame falls under is one which preserves this vacuum.
This may be extended to massive particles and massless particles. A massless particle is on a null geodesic and is then on a “null frame.” These frames are then projective varieties over massless quantum fields in that vacuum. These massless fields all have transverse modes, but no longitudinal modes. A massive particle has a longitudinal mode, and the vacuum modes have dispersion as a result. This is due to the presence of the Higgs field.
An accelerated frame is one which has a vacuum equivalent to a particular vacuum near a black hole. Depending on the acceleration parameter this can be a different vacuum. In this way aspects of spacetime physics can be thought according to quantum mechanical or quantum field properties. Spacetime is probably an emergent phenomenon of quantum physics.
Explanation:
The answer from the given choices is "campaign".
A campaign refers to an arranged arrangement of exercises that individuals complete over some undefined time frame with a specific end goal to accomplish something, for example, social or political change.If somebody battles for something, they do an arranged arrangement of exercises over some undefined time frame so as to accomplish their point.
