Describe how particles that make up an object change when the objects temperature increases

The motions of the particles that make up an object change when the objects temperatures increases because if the objects temperatures increases, the particles begin to move faster so the kinetic energy of the particles go really fast while the potential energy particles only increase when they go farther apart.

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

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
