Answer:
Atoms are single neutral particles.
example: Ne, O
Molecules are neutral particles made of two or more atoms bonded together.
example:O2,HCl
Answer:
The force of the impact would be smaller
Explanation: Examples:
If the force is big then the time would be small (2500N of Force = 10 seconds)
If the force is small then the time would be big (250N of Force = 50 seconds)
Impulse/Collision -> [Ft] = [M (vf-vo)] <- Change in momentum
Answer:
Explanation:
Both the pizza rolls are on two circular paths having different radii because one of them is on the rim and another is near the central axis. Their angular velocity are equal . That means they rotate by same angle in equal period of time. So in Δt they make equal angles at the centre. Hence their angular displacements are equal.
But length of arc made by them in equal interval of time that is Δt are different. Ir is so because their speed are different . Speed v and angular speed ω are related to each other as follows.
v = ω r .
So for objects in motion on circular paths having different radii , v are different even if their ω are same.
length of arc l = v Δt
So length of arc will be proportional to their v which will be proportional to r if their ω are same .
Hence length of arc will be proportional to radius of circular path, ie their distance from the centre .
Answer:
Atoms form chemical bonds to satisfy the Octet rule and become Stable element.
Explanation:
- Every atom desires to achieve total eight valence electron in their outermost shell to become stable. This rule is known as octet rule.
- During the chemical reaction process, every element goes through the process of receiving or donating the element to complete the octet rule to become stable.
- The electronic configuration of element having eight electrons in its valence shell is the noble gases.
When playing a Pro Set, you would have to win 8 games in order to be the winner, leading with an advantage of two or more games.
