Basically, this figure represents scattering of alpha particles by the atoms of a gold foil.
- Here, A represents that a few alpha particles are deflected through large angle. It shows that the nucleus of the atom is positively charged which repels the positively charged alpha particles and deflect them from their original path.
- B represents that most alpha particles pass straight through the gold foil without any deflection from their original path. The reason is that there is a lot of empty space in the atom.
- C represents that some alpha particles are deflected through small angles. The reason is same as that of A.

Answer:
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

hope this helps if not sorry :(
If its in the shape of a sphere its volume is 696.909703 or 697 cubic mm to the nearest cubed mm.
The answer is 600N because if its 600 and 0 its still going to be 600
Answer:
C. Reducing the air pressure allows the molecules to escape.
Explanation:
Lower air pressure can be found in the mountain or any high ground place. In this place, you will need less temperature to boil water or other liquid.
A liquid phase will change into gas when it reaches the vapor pressure of the surrounding air. At that point, the molecule can move freely as the gas phase. Since the atmospheric pressure is preventing the liquid to become gas, if the pressure is lower, the liquid can boil at a lower temperatures.
