At the macroscopic scale, kinetic energy would be present when .

objects visible to the eye are moving
subatomic particles are held together via bonds
subatomic particles are moving
objects visible to the eye are stationary

At the macroscopic scale, kinetic energy would be present when objects visible to the eye are moving

Explanation:

At the macroscopic scale, kinetic energy would be present when objects visible to the eye are moving

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

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
