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.
Question 2:
<span><u>slow, steady evolution of a small isolated population</u></span><span>
This evolutionary theory suggests that a species slowly and continuously evolved over a long period of time. This selection and variation happens more gradually. It is hard to notice over a short period of time. The change is slow, constant and consistent. In punctuated equilibrium, the changes come in spurts. There are periods wherein a huge change occurs and there are also periods with very little change. The mutation is at random. Genetic drift is the change in the frequency of a gene variant due to a random sampling of organisms. </span>
The Mississippi and the Amazon are quite different in that <u>C) the </u><u>Amazon </u><u>is much </u><u>longer </u><u>than the </u><u>Mississippi</u><u>.</u>
The Amazon River:
- Is the second longest river in the world.
- Is longer than the Mississippi.
The Amazon river is measured to be a distance of 3,969 miles whilst the Mississippi is around 3,896 miles which means that the Amazon is longer than the Mississippi.
In conclusion, option C is correct.
