The bigger Mass takes more Force to accelerate to the ground. The smaller Mass takes less Force to accelerate toward the ground. Coincidentally gravity exerts more force on the bigger mass and less force on the smaller Mass. The result is that all objects fall with the same acceleration. All objects reach the same speed after the same falling time. And all dropped objects hit the ground at the same time. We've known this for about 300 years.
Let's assume that the pressure given is 771 torr.
Answer:
747.44 torr
Explanation:
The eudiometer tube is a setup that collects gas in a liquid (generally water). After the thermal equilibrium, the gas becomes in equilibrium with the vapor of water above the liquid.
By Dalton's law, the total pressure of a mixture is the sum of the partial pressure of its components. The partial pressure is the pressure that the gas would have at the same conditions if it was alone. So, the pressure of the dry gas is its partial pressure.
The total pressure is the barometric pressure, and the partial pressure of the water vapor at 20°C is 23.56 torr (the value can be found at a thermodynamic table). So, the pressure of the dry gas (P) is:
771 = 23.56 + P
P = 771 - 23.56
P = 747.44 torr
Autonomic, but I don’t know why! Research this if you can.
Answer:
it is long.
Explanation:
I know the answer but I don't know how to explain it
Moving clouds. The doppler effect is specifically used to measure motion.
