Answer:
The true statement is that different gases with the same mass and temperature always have the same average kinetic energy. This is one of the postulates of the kinetic theory of matter.
If we two objects A and B, they will have mass mA and mB and velocity vA and vB respectively. If K.E = 1/2mv^2 . Then it follows that
1/2mAvA = 1/2mBvB. Since the mass is the same it means the velocity of the two objects should be the same so that they have the same average kinetic energy.
Answer:
The real observations are:
Moon rises in east, sets in west each day.
stars circle daily around north or south celestial pole
Positions of nearby stars shift slightly back and forth each year.
A distance galaxy rises in east, sets in west each day.
We sometimes see a crescent Jupiter.
Explanation:
Mercury it can seen from the Earth but no it phases.
Moon is seen in all parts of the Earth, the only difference is that in north pole the stars moves parallel to the horizon.
By the rotation of Earth the relative position of stars changes a little bit.
In the north pole a galaxy can be observed and in the south pole 2 galaxies.
Jupiter is one of the planets that can be seen from Earth in some seasons and it changes the position due to the rotation of planets around the sun.
A planet beyond Saturn is not possible to be observed from Earth just with the naked eye.
the capital of iran is Tehran or Teheran.
Answer:
Cylindrical map projections
Explanation:
Cylindrical map projections are used for portraying the Earth. Cylindrical map projections are rectangles, but are called cylindrical because they can be rolled up and their edges mapped in a tube, or cylinder. They have straight coordinate lines with horizontal parallels crossing meridians at right angles. All meridians are equally spaced and the scale is consistent along each parallel. The only factor that distinguishes different cylindrical map projections from one another is the scale used when spacing the parallel lines on the map.
Cylindrical map projections are great for comparing latitudes to each other and are useful for teaching and visualizing the world as a whole, by determining continents, languages, etc but really aren’t the most accurate way of visualizing how the world really looks in its entirety.
The answer would be A) Ganymede
