This effect is explained by increased chain entanglements at higher molecular weights. Increasing the degree of crystallinity of a semicrystalline polymer leads to an enhancement of the tensile strength. Deformation by drawing increases the tensile strength of a semicrystalline polymer.
Answer:
a
Explanation:
you will find out that an object that has more weight requires more energy to move than the one with less weight
Explanation:
When an object slows down, its acceleration is opposite to the direction of its motion. This is known as deceleration.
I don’t understand what are you trying to do ?
The frictional force is always act in opposite direction of motion. if wheels is moving in +x axis or right then the f force is act in -x or left
