Explanation:
The acceleration g varies by about 1/2 of 1 percent with position on Earth's surface, from about 9.78 metres per second per second at the Equator to approximately 9.83 metres per second per second at the poles.
Answer:
(B) sound/kinetic
(E) Gravitational/kinetic
(F) mechanical/sound
Explanation:
(B) the useful energy transfer is sound but a by product of that is kinetic or mechanical energy because of the vibrations needed to make sound
(E) the useful energy transfer is Gravitational potential but a by product of that is kinetic or mechanical energy
(F) the useful energy transfer is kinetic or mechanical energy but the byproduct is noise and occasionally heat
Geocentric Theory
In astronomy, the geocentric model is a superseded description of the Universe with Earth at the center. Under the geocentric model, the Sun, Moon, stars, and planets all orbited Earth
Heliocentric Theory
Heliocentrism is the astronomical model in which the Earth and planets revolve around the Sun at the center of the Solar System. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center
G-Theory is the earth is the center of the universe.
H-Theory is the sun is the center of the universe.
Answer:
Explanation:
1. Many buyers and sellers participate in the market.
2. Sellers offer identical products.
3. Buyers and sellers are well informed about products.
4. Sellers are able to enter and exit the market freely.
The mind boggles at the spectacle ... a 150-kg lady weighs about 330 pounds, and has the courage and the audacity to not only go to the beach, but to go out and float in the water, hoping that there are no wise little kids around, getting ready to yell to each other "Thar she blows, Cap'n !".
But we're only here to do the math, whether or not it has any physical significance in the real world.
This problem is really not that mysterious.
Since the star of this unlikely scenario is just barely floating, her weight must be equal to the weight of an equal volume of water. In other words, her average density (arrghhh, I can't take much more of this) is equal to the density of water.
Officially, 1 kg is the mass of fresh water that occupies a volume of 1 liter, so this relationship also very nearly describes the relationship between our heroine's mass and volume.
Her volume is very nearly 150 liters, or 0.15 cubic meter, and no further rounding is necessary, in more ways than one.
I would stay and convert that to some more familiar 'customary' units for you, honest I would. But I've been quite overcome by my visualizations of this whole matter, and I really must make a quick trip to the rail, immediately.
