NO. although the arrangement of the atoms will change, the total number stays constant.
Answer:
Explanation:
tangential acceleration at = 3.1 m / s²
angular acceleration = tangential accn / radius
= 3.1 / r , r is radius of the cylinder .
IF N₁ be no of rotation in time t
θ = 1/2 α t² , α is angular acceleration , θ is angle in radian covered in time t
2π N₁ = 1/2 (3.1 / r ) x 2.9²
N₁ = 2.0757 / r
similarly we can calculate
2πN₂ = 1/2 (3.1 / r ) x 10²
N₂ = 24.68 / r
N₂ / N₁ = 11.89

Answer: 1) Boils</h3>
The less air pushing down on the water effectively allows the water to boil easier. Think of the water molecules as a bunch of marbles bouncing around in a box with a lid. The less air pressure means the lid is easier to open from the force exerted by the bouncing marbles, allowing those particles to escape and turn into gas.
So in short, if you are in the mountains, then it'll take less time to cook food because water comes to a boil faster.
S = ?
U = 0
V = ?
A = 9.81
T = 2
we tryna find s
lets use s = ut + (at^2)/2
ut cancels out since u = 0
(at^2)/2 = (9.81 x 2^2)/2
= 19.62m
True is the answer to this question I think.
