I have no idea
sorry
good luck thooooo!!
Answer: The amount of movement of the particles depends on the amount of <u>force</u> acting on them and their relationship to other atoms.
Explanation:
The inter-atomic force determines the inter-atomic distance which governs the amount of movement of the particles.
For example in solids, the inter-atomic force is stronger and hence, the distance between any atoms is very very small which restricts the movement of the particles. On the other hand, in case of liquids and gases, the inter-atomic forces are not very strong and there is more distance between the atoms which allows free movement of particles.
Electron
3-4-6
proton
1-5-7
neutron
2-5-7
Because Helium fusion in a shell outside the core generates enough thermal pressure to push the upper layers outward.
Answer:
A person climbs a set of stairs
Explanation:
Potential energy is said to be possessed by an object due to its position. As the height from the ground level increase, the potential energy increases. It is calculated by the below formula as :
P = mgh
Out of the given options, the option that illustrates an increase in potential energy is option (b) i.e. a person climbs a set of stairs. As he steps one stair, its position from ground increases. It means its potential energy increases.
