Answer:
Encouraging your preschooler’s creative play
For your preschooler, time, materials and space to be creative are very important.
Preschoolers like to be spontaneous in their creative play, so it’s good to follow your child’s lead. But there’ll also be times when your child wants you to be more involved in her creative activities. By being actively involved, you can develop your child’s skills and understanding.
Answer:
specialist focus in one very specific thing, generalist focus and many things, they are like a jack of all trades
Answer:
(a) Increases
(b) Increases
(c) Increases
(d) Increases
(e) Decreases
Explanation:
The tensile modulus of a semi-crystalline polymer depends on the given factors as:
(a) Molecular Weight:
It increases with the increase in the molecular weight of the polymer.
(b) Degree of crystallinity:
Tensile strength of the semi-crystalline polymer increases with the increase in the degree of crystallinity of the polymer.
(c) Deformation by drawing:
The deformation by drawing in the polymer results in the finely oriented chain structure of the polymer with the greater inter chain secondary bonding structure resulting in the increase in the tensile strength of the polymer.
(d) Annealing of an undeformed material:
This also results in an increase in the tensile strength of the material.
(e) Annealing of a drawn material:
A semi crystalline material which is drawn when annealed results in the decreased tensile strength of the material.
Answer:

Explanation:
From the concept of Hooke's Law,

where;



Recall:




Thus, the stress in the pipe at the maximum allowable contraction = 264.6 Mpa
