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.
In Ptolemy's earth-centered model for the
solar system, Venus's phase is never full as viewed from earth because it
always lies between earth and the sun. In reality, as Galileo first recognized,
Venus is full.
<span>Venus is closer to the Sun than Earth. That
is why we cannot see the full Venus. However, Venus is full (whenever it is on the opposite side
of the Sun from Earth). From Earth, Venus's phases range only between new and
crescent.</span>
