Stretching a rubber band is a physical change.
a rubber band is still rubber because if u stretch it it wont change
To make a catapult, a rubber band and a small stick that is V-shaped is required. The rubber band should then be tied on either side of the V-shaped stick to make the catapult.
It is expressing a change in the value of something as a percentage of its original value. So, if the original value (V) changes to the new value (W) then the change is W - V. Then, the relative change is (W - V)/V and the percentage change is 100*(W - V)/V = 100*(W/V - 1)
Yes - it's still a rubber band.
Actually, I believe you mean the wiper rubber blade. It will state at the back of any good replacement blade on how to change it. Most dealers themselves would do it for you. Let us know if this helps.

Yes, a flat tire is considered a physical change because the rubber material in the tire is simply being compressed and there is no change in the chemical composition of the rubber.
Stretching a rubber is a physical change because the rubber's molecules are simply being rearranged without any new substances being formed. Chemical changes involve the creation of new substances with different chemical properties.
