Chemical reactions happen when you breathe, eat, drink, etc. Chemical reactions make you go through puberty, chemical reactions makes things enjoyable, or sad. Chemical reactions happen in batteries, cellphones, computers, vehicles.
<span>Chemical reactions are everywhere and too numerous for me to think about all the possibilities.</span>

Answer:
Explanation:
angular momentum of the putty about the point of rotation
= mvR where m is mass , v is velocity of the putty and R is perpendicular distance between line of velocity and point of rotation .
= .045 x 4.23 x 2/3 x .95 cos46
= .0837 units
moment of inertia of rod = ml² / 3 , m is mass of rod and l is length
= 2.95 x .95² / 3
I₁ = .8874 units
moment of inertia of rod + putty
I₁ + mr²
m is mass of putty and r is distance where it sticks
I₂ = .8874 + .045 x (2 x .95 / 3)²
I₂ = .905
Applying conservation of angular momentum
angular momentum of putty = final angular momentum of rod+ putty
.0837 = .905 ω
ω is final angular velocity of rod + putty
ω = .092 rad /s .
A car traveling in a straight line at a constant speed has a constant velocity, but if the car turns around a curve in the road then the velocity changes, even if the speed stays the same. Or a car that is changing in speed, even if it continues in the same direction, has a changing velocity.
