Question 3plasticity refers to the: a. fact that many academic fields contribute data to the science of development. b.ability of human traits to be molded during development. c.universals and specifics of human development in many cultural settings. d.vast array of contexts in which development occurs.

B.ability of human traits to be molded during development.

Explanation:

Plasticity:

 1.When pressure is applied then some deformation occurs and to retain this deformation is known as plasticity.

2. It is the capacity of molding

Plasticity refers to the ability of human traits to be molded during development.

So the option B is correct.

B.ability of human traits to be molded during development.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
