it is size of of particles because it does not matter about the size in a closed container
Explanation:
It is given that,
The ramp is tilted upwards at 25 degrees and Paul is pulling a large crate up the ramp with a rope that angles 10° above the ramp.
Total angle with respect to ramp is 35 degrees.
If Paul pulls with a force of 550 N.
The horizontal component of the force is given by :



The vertical component of the force is given by :



Hence, this is the required solution.
The awnser would be True. Hope I helped!
NO. although the arrangement of the atoms will change, the total number stays constant.
