Which statement about atmospheric pressure is false?
Vinil7 [7]

Answer:

D) With an increase in altitude, atmospheric pressure increases as well.

Explanation:

Generally when altitude increases, the value of pressure decreases. This shows that pressure is inversely proportional to altitude. For example, the higher the altitude, the lower the pressure and vice versa. At very high altitude, the number of molecules of air are smaller than the number of moles of air at very low altitude. Thus, the higher the altitude, the lower the atmospheric pressure and the lower the altitude, the higher the atmospheric pressure. Therefore, option (D) is false.

Molarity formula what is the molarity of a solution in which 3 moles of nacl is dissolved in 1.5 kg of water
Igoryamba
Molarity is..
1.5 kg H₂O = 1.5L H₂O
So...
\frac{moles}{volume} = molarity
\frac{3.0 mol}{1.5L} = molarity
2M = molarity

Kepler’s second law of planetary motion states which of the following?
aev [14]
Kepler stated three laws of planetary motion.

First law states that the pathway of a planet is an ellipse with the Sun at one of the foci.

Second law states that an imaginary line joining the Sun and a planet sweeps out equal areas during equal lengths of time.

Third law states that the square of the period of the orbit of a planet is directly proportional to the cube of the length of the distance from the Sun.

Therefore, the answer is that Kepler's second law of planetary motion states that planets cover the same area during equal time periods.
